Energy savings through PM technology in pivot irrigation systems


2023 07 Tecnopompe EN

In Italy, three well systems were equipped with permanent magnet motors to achieve long-term energy savings. 

For two pivot irrigation systems, G.N. Tecnopompe from Castel Mella / Lombardy Italy installed three pumping systems with permanent magnet motors. The pump systems feed pivot irrigation systems which were set up to reduce water consumption as much as possible in order to counteract the climatic and structural problems related to energy and water consumption. Especially in Italy, the importance of this issue is constantly growing. Therefore, it was all the more important for the customer to focus on energy efficiency and sustainability also in the selection of the pumping system.

In addition to drilling the three wells, G.N. Tecnopompe also took care of the complete installation and setup of the system.

To create an energy-efficient, sustainable solution, the decision was made to use Franklin Electric permanent magnet motors, which are characterised by very high efficiencies.

By using Franklin Electric‘s 37 kW permanent magnet motors in combination with powerful pumps, savings of at least 7 kW can be achieved at full power.

It quickly became apparent that high savings could be achieved when using a coordinated system with permanent magnet motor and frequency converter.

Both the energy consumption and the water consumption could be reduced considerably. Due to the savings achieved, a considerable part of the investment can already be amortised in the procurement year.

Applications at a glance:

  • Franklin Electric 6" Permanent magnet motor
  • submersible pump
  • DrivE-Tech Variable Frequency converter

Energy savings through permanent magnet technology

In all industrial sectors and markets, energy consumption is becoming a decisive criterion when selecting new systems and modernising existing ones. When pumping water from boreholes or tanks, this is also becoming one of the most important aspects along with optimal dimensioning and the reliability and quality of the system. Since the energy consumption of a pump system accounts for up to 90 % of the total life cycle costs, the operating costs can be reduced considerably.

Franklin Electric has developed the High Efficiency Pump System, which enables energy savings of up to 21 %. The key factor for energy savings and superior efficiency is the permanent magnet technology of the motor. Instead of a short-circuit induction type rotor, the high efficiency motor contains a permanent magnet rotor design with buried magnets with significantly improved efficiency and overall lower energy consumption compared to a standard induction motor. The Permanent Magnet Motor design eliminates electrical rotor losses resulting in lower motor amps, improved partial load behavior and reduced temperature heat rise.

Franklin Electric offers permanent magnet motors in a package with ideally matched components to further optimise efficiency and energy savings. This so-called High Efficiency System includes the PM motor, a submersible pump, a frequency converter and additional components such as a suitable output filter and, if necessary, a flow switch.

Numerous installations worldwide impressively demonstrate the success of this system, where great savings could be achieved. In most cases, the system pays for itself in less than 2 years.

HES supplies monks on Mount Athos with solar-powered drinking water


2023 07 Mount Athos EN

Solar-powered drinking water supply

On Mount Athos in the Agio Oros region of north-eastern Greece, a new 4" High efficiency solar pumping system of Franklin Electric supplies an Orthodox monastic community with drinking water from a well. The particular challenge was that the area has no connection to the electricity grid. It was therefore decided to use a solar application to pump the necessary water from the 50-metre-deep well.

Fluida Pumps and pump equipment from Bulgaria took on this project and explored the possibilities. Looking for the best efficiency at a flow rate of 2 to 5 m³/h, they quickly decided on the High Efficiency pumping system of Franklin Electric. As the area has no connection to the electricity grid, a solar application had to be installed. A system with 10 solar modules was installed for this purpose.

4" High Efficiency Solar pumping system

  • 4" submersible pump VS 4/14
  • 4" permanent magnet PM motor 1.1 kW / 220V / 100 Hz / 4000N
  • Solar Variable Frequency converter DrivE-Tech MINI Solar 2.011 MP

Another difficulty with the installation was that the area also has no internet access. So it was not possible to control and set up the system remotely. All data was coordinated in advance with the Franklin Electric support team so that the installation could take place smoothly on site.

Coordination with the customer was also difficult, because the monk was only available once a day at 6 a.m. to clarify open questions. Today, the well produces water reliably and supplies the monks with water every day.


Voltage boost and reduction of solar modules

Solar applications are about converting sunlight into electricity. The most important value is the so-called solar radiation (measured in W/m²). This number tells you how much energy you can get from the actual sunlight. The solar radiation depends on your location and changes with the time of day, with the weather conditions and also during the year. Each day you only have a certain window of time where you have enough sunlight to keep your system running at full speed. So the solar system must be carefully sized to achieve the desired system performance. In addition to solar irradiance, this will depend heavily on the number of solar panels and how well your solar drive controls motor and pump. The MVPT algorithm of the High Efficiency system maximizes system performance.

So, when operating a pump with solar energy, it is important to generate sufficient electrical power, but even more important is sufficient voltage. The pump speed and thus the system performance is determined by the electrical voltage. To generate enough voltage, you need to connect enough solar panels in series. This will generate the voltage level needed to operate at full speed.

But if weather conditions change, the voltage can drop, causing the system to immediately reduce pump speed to keep running. This reduces the amount of water pumped, but not just linearly. Due to pump affinity laws, the pump head or pressure is reduced squared, which then leads to a further reduction in water flow as you run at a different pump operating point.

So, if you haven’t sized your system carefully, or if you’re using low efficiency components, you run the risk of running in what’s called a dead head situation. The pump is still operating, but it’s not generating enough head to overcome a certain level, and the result is that water flow stops. With the lower energy consumption of the High Efficiency System, you have an additional safety reserve that allows you to pump more water, or longer.

Franklin Electric has further enhanced this feature on its smaller 4” systems by adding a solar frequency inverter to provide an advanced voltage boost function. This voltage boost feature makes it possible to size your system based on power rather than voltage, saving you up to 50% on solar panels compared to a standard system without the voltage boost feature. The bottom line is that you need fewer solar modules, which reduces the initial investment and installation cost, and you also save on solar module mounting.


FNC End-suction Centrifugal pump supplies water to three fountains in Hilden town park


2024 04 FN Pumps Hilden EN


A Franklin Electric FNC Close-coupled End suction Centrifugal pump with extended shaft supplies water to the fountains in the Hilden municipal park.

FNC End suction pump

The well maintenance department of BPK Brunnen- und Pumpen-Service GmbH in Moers/Germany replaced a standard centrifugal pump that supplies water to three fountains in the Hilden town pond.

When it came to selecting the right pump, the decision was made in favour of the powerful FNC 80-160/110 pump with 11 kW, which achieves flow rates of up to 156 m³/h (50 Hz) and heads of up to 28 m (50 Hz). In addition to the required performance parameters, criteria such as high quality and durability and corrosion resistance were also decisive in the selection of the pump.

Another fountain in the Hilden city park is currently being equipped with a submersible pump from Franklin Electric, which achieves a delivery rate of up to 144 m³/h and a delivery head of up to 578 m.

The renovation of the fountains was part of an inner city project that also included the upgrading of the centrally located city park with its pond. The fountains of the water body does not only look beautiful and please visitors, but  also is important for the circulation and aeration of the water body.

How a Franklin Electric 6" pump system brought the Bardolino fountain back into operation


2022-03 Header Bardolino EN

The Seaman’s Fountain of Bardolino in Italy is working again after two years, thanks to the Franklin Electric pump system, consisting of a 6" pump with a 6" encapsulated motor.

Pressure boosting for water games

The musical fountain of Bardolino on the shores of Lake Garda, designed in 2001, was finally back to bubble again after two years of standstill, thanks to a visual and technical redesign by a local company. The new system consists of a 6" pump system from Franklin Electric, which was provided by the company Idroagrifer in Pastrengo (VR). Idroagrifer is a Franklin Electric distributor of borehole systems in the Veneto and Trentino Alto Adige area.

In this type of ornamental fountain, the pump system pushes the water through jet nozzles. This increases the pressure and the fountains reach the desired height.

The 6" systems from Franklin Electric consist of a 6" encapsulated submersible motor and a 6" Stainless steel submersible pump, which are characterised by high reliability and durability.

Reliability and robustness

Franklin Electric‘s submersible motors allow power ratings up to 45 kW and are equipped with hermetically sealed windings. This anti-tracking system provides mechanical support, isolates the winding in the stator and ensures rapid heat dissipation.
The motors are equipped with the SandFighter® sealing system with SiC/SiC mechanical seal and sand protection as standard. The hydrodynamic liquid-lubricated radial bearings and heavy-duty Kingsbury type thrust bearing also ensure 100% maintenance-free operation.

The 6" submersible pumps of the VS series are made of Stainless steel and guarantee a long service life. Thanks to the proven components, this pump can withstand the toughest environments. It is suitable for flow rates up to 80 m³/h. The maximum permissible sand quantity for this series of submersible pumps is 100 g/m³.

The water installation is dedicated to Saint Alberti, a navy engine mechanic who went on board the submarine Topazio during the Second World War, which did not return to base in 1943 after a war mission.
Today, the sprinkler fountain, whose play of lights is reminiscent of the Italian colours, delights both tourists and locals walking along one of the most famous shores of Lake Garda. And thanks to the durable Franklin Electric integrated products, it will continue to do so for many years to come.

Why EH / EV pumps are ideal for increasing water pressure in irrigation systems


2022-02 USE CASE_Fertirrigation header_EN

Approx. 30 multistage pumps of the EH (horizontal) and EV (vertical) series have been installed in various irrigation systems in Veneto (Italy) for pressure delivery in the distribution of water-fertiliser mixtures in distribution channels.


Requirements for irrigation systems constantly increasing

In cooperation with Irrigazione Gastaldelli, who organises the installation of irrigation systems, Franklin Electric
supplied about 30 multistage pumps to 10 local agri-food companies in Rovigo, Verona, Padua and Ferrara. Both for fruit growing (pears and blueberries) and for vegetable cultivation in greenhouses and in the ground, the ideal
suitability of Franklin Electric’s pump systems was demonstrated.

Fertiliser irrigation technology is becoming increasingly common in agriculture as it maximises the management of raw materials such as water and water-soluble fertilisers, and reduces the risks associated with water shortages. Advanced technologies can optimise the fertiliser irrigation process enormously. However, this requires high precision in dosing and scheduling of the system to distribute the necessary nutrients to the plants in a targeted manner.

The advantages of fertiliser irrigation lie in the reduced manpower requirements due to the automated processes,
in the reduced impact on the soil due to tillage without use of agricultural equipments and in the better distribution of the fertiliser. In addition, there are fewer scattering losses with nutrient-water solutions, as drip irrigation precisely targets the root of the plant. However, this technique also has disadvantages, as it can only be used for irrigated crops and it is always necessary to use a technologically advanced and therefore often expensive system compared to traditional methods.


Avoidance of corrosion, unnecessary repairs and downtime

Because the technical demands on the irrigation systems (greenhouse or ground) are high, all parts of the system
must meet the highest quality standards in terms of performance, materials and flexibility.
For this reason, Franklin Electric‘s multistage pumps are the first choice for these systems. The Stainless steel construction ensures good resistance to the highly corrosive fertilisers and long-term reliability, avoiding unnecessary system downtime due to component replacement.

The excellent performances and the wide range of flow rates, up to 29 m³/h for the horizontal EH series and up to
115 m³/h for the vertical EV series, allow pressure modulation to meet the requirements of any system. Appropriate water pressure is needed to ensure the necessary mixing of water and fertiliser, and thus the supply and growth of the plants.
Franklin Electric‘s multistage pumps can ensure this high pressure and thus distribute the perfectly composed solution with micro-sprinklers in the right amount over the entire extent of the plant. This guarantees each seedling the necessary nutrient supply.


Flexibility for all needs

The pressure booster pumps must transport the water-fertiliser solution from the tanks into the system. The space
available to place the pumps and the distances that have to be covered when transporting the liquid to the plant
vary greatly. Franklin Electric therefore offers a wide range of pumps to provide the optimum solution for each application. The horizontal multistage pumps make it possible to save space at height, while the vertical multistage pumps are suitable for applications with little usable installation space.

In addition, Franklin Electric offers a wide range of accessories, from pressure vessels to shut-off valves and special designs such as self-priming horizontal pumps or vertical high-pressure pumps connected in series.
Last but not least, the DrivE-Tech and Drive-Tech MINI frequency converters optimise the operation of the pumps
through state-of-the-art electronic technology.

How the EV and EH DTm booster sets ensure water supply at the historic Thruxton race track


2022 02 Evpluseh Thruxton Race Court

The historic Thruxton race track located in the south of the UK has been equipped with new water boosting sets powered by Franklin Electric, high quality pumps and smart controls offer a reliable solution with efficiencies in mind.

Increased requirements on pressure and flow

As the Thruxton racecourse site has grown over the years, the owners found that the water system struggled to maintain required flow and pressure.

Henry Gill of HG Water was therefore approached to design a new booster system for the historic racecourse‘s water supply that could keep up with the increased water demand.

The complete water booster packages were supplied by KGN Pillinger, a British water booster manufacturer. Richard Sharp (Business Development Manager) says that when it came to selecting the components, it was quickly clear that Franklin Electric‘s E-Tech product would be chosen, as the quality and competitive price of the Franklin Electric installation allowed KGN to build high quality equipment within the customer‘s budget.


Booster systems supply the racetrack

The installation is based on a booster set made by two vertical multistage EV10 pumps, each one equipped with DrivE-Tech 2.030 frequency converters, coupled in parallel via manifolds, shut-off valves and check valves. The DrivE-Tech frequency converters modulate the operating frequency in order to maintain a constant set value.

The system is complemented by an EH Dtm multistage horizontal pump, consisting of an EH 5/5T6 pump and the DrivE-Tech MINI integrated frequency converter.

Overall, the project includes new storage tanks, kiosks and booster pumps, as well as the variable-speed controls to feed the different areas of the site. The old piping was re-routed to the new kiosks, and thanks to the additional storage tank, sufficient water can now be distributed even during peak periods.


> The vertical multistage pumps from Franklin Electric offer high levels of efficiencies within a robust design and when used with the DrivE-Tech variable speed controls the increased demands can now be met. <  (Henry Gill of HG Water)

Energy savings for geothermal heating systems with HES


 Headline Geothermal Installation HES UK

With the right components, the efficiency of a heating system with well installation can be increased and energy costs sustainably reduced. Geoquip Water Solutions in the UK recommends the combination with the High Efficiency System from Franklin Electric.

The increasing demand for renewable energies is causing the increasing numbers of geothermal heating systems in both the commercial and private sectors. Savings of up to 80 % compared to conventional fossil fuels and the reduction of CO2 emissions are among the advantages. In addition, there are various possibilities of financial subsidies from the legislators.

In addition to systems with geothermal probes and geothermal collectors, there is the option of operating a heating system with a well system. The two wells, the so-called suction and absorption wells, transport groundwater to the surface and use the heat of the groundwater as an energy supplier for water-water heat pumps, which extract the heat from the groundwater to heat rooms and process and drinking water in the house.

Since groundwater is an important resource for plants and living organisms, it must be recirculated. The pump in the suction well pumps the groundwater to the surface. After the thermal energy has been recovered in the heat exchanger, the now colder water is pumped back into the ground water via the absorption well. When positioning the two wells, it is important to consider the flow direction of the groundwater.


Immense savings potential through the right borehole pump

With geothermal heating systems, special care must be taken at the planning stage, because the potential savings over the lifetime of such a system are immense if the system is correctly dimensioned from the outset. The cost of purchasing and installing a typical geothermal heat pump system in an average house in the UK is around 14,000 to 19,000 pounds. A multiple of this costs the energy that is invested over the entire life of the system. It is therefore worthwhile to design the system ideally in order to achieve the maximum benefit.

The first thing to do is to make sure that the most efficient geothermal heat pump is used for operation, which also applies to the extraction pump in an open-loop system. This may sound obvious, but it makes no sense to have a „green“ geothermal heating system if the source pump is working around the clock and consuming far more electricity than necessary to move the water in the loop.

Therefore, the selection of the right components in particular is crucial. In an open-circuit system, the borehole pump is an important component of this. If the right pump for the job is not chosen here, the system cannot run effectively.


Permanent magnet technology as the key to outstanding efficiency

The key factor in these energy savings is the efficiency of the motor‘s permanent magnet technology. Instead of a short-circuit induction rotor, Franklin Electric uses a permanent magnet rotor design with integrated magnets. The total electrical rotor losses of a motor are eliminated, resulting in a significant improvement in efficiency. In addition, the PM motor has lower heat generation and requires less current to run at the same pump load. A frequency converter is required to operate a PM motor.


Remote control via App

The system is available in the sizes 4" 6", 8" and 10". Included are a submersible motor, a submersible pump, a frequency converter and the matching output filter.

The 4" system also offers the ability to remotely control and monitor system performance in real time using an App. Franklin Electric‘s support team can also access the system in this way to assist with problems or setting new parameters.


For Geoquip Water Solutions, the HES is the most energy-efficient solution

Mike Deed, Managing Director of Geoquip Water Solutions, has more than 30 years’ experience in the water treatment and solutions sector. He works with strategic partners to ensure customers receive the maximum benefit from their investment. He believes that the most energy efficient solution on the market is the High Efficiency Borehole System (HES), designed and manufactured by Franklin Electric.

» Here, Franklin Electric has set new standards in energy efficiency, because unlike most systems on the market, this system is not equipped with an - usually less energy-efficient - asynchronous motor, but uses an asynchronous NEMA standard permanent magnet motor, which has achieved motor energy savings of up to 21 % compared to standard asynchronous motors in numerous installations worldwide.«

The HES selection and sizing tool provided on the Franklin Electric website helps to select the right system. This tool can also be used to compare energy savings based on runtime and current energy prices. Systems typically pay for themselves within the first two years.

As with all things, being armed with the right information and components makes a difference. Given the long-term benefits that can be achieved through geothermal systems, it is definitely worth investing in the best.


This is how the thermal heat is obtained

The water-to-water heat pump transfers the thermal energy to a special refrigerant. This is initially liquid and evaporates when it absorbs the thermal energy. It then flows through a scroll compressor, which in turn increases the pressure and temperature of the medium. In the process, the steam is passed through two interlocking spirals. As one of the spirals moves eccentrically in circles, several gas spaces are created between the spirals, which become smaller and smaller towards the inside of the component, thus causing the pressure to rise. In the middle of the scroll compressor, the gases are finally pressed into the connected pipe. Here, the transported energy is transferred to the heating water. The refrigerant vapour cools down and liquefies again.

The efficiency of the system depends on the temperature difference between the design temperature of the heating system and the temperature of the environmental heat source. The groundwater is about 10 °C all year round. The compressor therefore does not have to use as much energy to raise the temperature, which makes the system very energy efficient.

How vineyards are irrigated with cost-saving using the 4" Solar HES


2021 03 Vineyard Spain HES4 Solar EN

In Spain, a vineyard is irrigated using the 4" Solar High Efficiency System. The customer’s initial skepticism quickly turned into enthusiasm about the enormous cost savings and the excellent support during commissioning.


Solar system for irrigation

The 4" High Efficiency System was installed in a customer‘s vineyards in central Spain for irrigation. The system consists of the following components:

  • 4" Encapsulated permanent magnet Solar motor 3 kW, 220 V
  • 4" submersible pump VS4
  • Variable frequency drive DrivE-Tech 3.030 Solar MP
  • flow switch

 The system was connected to 2 x 9 PV panels of 275 watts each.


Cost reduction through the HES

The local Franklin distributor Likitech assisted the customer during selecting the right system and commissioning. The customer was initially skeptical about using Franklin Electric‘s High Efficiency System because he had been using a competitor‘s system. However, knowing the high quality of other Franklin products, he was finally convinced. Also the promise that Franklin Electric‘s Technical Service would provide remote support during the commissioning of the system and would also assist the customer with any future problems, made the customer trust in Franklin. Ultimately, he is thrilled with the results, as the system is operating even more efficiently and cost-saving than expected. Franklin Electric is setting new standards with its High Efficiency Systems (HES) up to 250 kW, achieving energy savings of up to 21% compared to systems with asynchronous motors.

While it is also the combination of perfectly matched components, the decisive factor in the energy savings is the highly efficient permanent magnet motor technology, which almost completely reduces rotor losses and thus significantly motor current and heat rise. In many cases, reduced motor current equals less drop cable cross sectional area further reducing overall installation cost.

And in the case of solar systems, the MPPT algorithm and integrated voltage boosting (up to 2.2 kW) ensure that the number of solar modules can be significantly reduced, as the system output is maximized accordingly.

How plants are irrigated from a well on Paros with the 4" Solar HES


1200 X 630 Px Solar HES On Paros Greece

A farm irrigates its crops with water from a 100-meter-deep well. This is pumped with the help of a 4-inch solar well system from Franklin Electric and solar energy from 9 solar panels.

Solar system for watering plants from a water tank

A farm on the island of Paros in Greece installed Franklin Electric‘s 4-inch High Efficiency System (HES) to pump water from a well application into a water tank for crop irrigation. The water is pumped from a depth of approximately 100 meters. 

Installed is a Solar High Efficiency System with the following components:

  • Encapsulated 4" Solar motor 200 V three-phase 2.2 kW with permanent magnet technology
  • 4" submersible pump VS2/20
  • Frequency converter Drive-Tech MINI Solar 2.015 MP
  • Level switch for the water tank

Energy savings of up to 20%

Franklin Electric is setting new standards in energy savings and efficiencies with its High Efficiency systems. Compared to standard asynchronous motors, savings of up to 20% have been achieved in the numerous systems already installed worldwide. It is the combination of perfectly matched components and their control: motor, pump, frequency converter and, if necessary, output filter harmonize perfectly from a technical point of view. First and foremost, however, it is due to the highly efficient permanent magnet motor. The technology eliminates rotor losses and thus significantly reduces current and self-heating. In many cases, the current reduction achieved leads to smaller cable cross-sections, which in turn has a positive effect on overall costs.

Setting up the system remotely

Even though the commissioning of the system is very intuitive thanks to the Franklin Electric app solution, it sometimes takes a bit of intuition and experience to find the right settings.
It‘s a good thing that Franklin Electric customers can rely on the assistance of the Technical Support in such cases! Since the system can even be controlled remotely via the mobile app, the customer was helped quickly.

In this application example, the system was commissioned in bad weather, not the best starting conditions for a solar system. However, Franklin‘s experts were able to adjust the parameters so that the motor turned and water was pumped despite the bad weather conditions. When the sun came out, the system ran optimally and pumped about 2.0 m³/hour. water, so that the water tank filled up quickly.

How the EH Dtm booster system controls flow and pressure on a poultry farm


1200 X 630 Px Poultry Farm UK EN

A poultry farm in England implements Franklin Electric’s EH Dtm multistage horizontal pump to reliably control and incrementally increase low flow and pressure to best suit the drinking water needs of young birds.

Control of flow and pressure

When raising chicks, it is enormously important to provide the animals with as much fresh water as they need, and this varies enormously as the animals grow. The biggest challenge here, especially during the growth period from two-day-old chicks to 34-day maturity, is controlling the flow of potable water to the production units. The pumps are typically installed in large on-site water storage tanks, from where the water is routed through the necessary filtration systems and drinking lines to the animals.

At the same time, the requirements for the new system were very high. Initially, the young animals require only very small, slow amounts of water, but the demand gradually increases, so the system had to be able to gradually increase the flow and pressure. As more and more emphasis is being placed on the energy balance of the systems when making new purchases, the new systems not only had to meet the high demands, but also be optimized in terms of energy by reducing energy consumption and increasing the efficiency of the system.

Pressure boosting system with 24/7 monitoring

Agri Management Solutions (AMS) in Hereford, England, provides water and irrigation services to poultry farmers. Working with Franklin Electric and its strategic partner Geoquip Water Solutions, the company‘s exacting requirements were met in full by installing a state-of-the-art booster system from Franklin Electric.

The EH Series multistage booster pumps are designed to meet all pressure boosting requirements. The stainless steel construction provides high performance in a variety of applications. The EH Series is offered in five flow rates and various power sizes (single-phase or three-phase) for a wide variety of applications.

The EH Series multistage vertical pumps are combined with the new Drive-Tech MINI inverter to increase the energy savings potential of these pumping systems. The Drive-Tech MINI uses innovative technology that ideally combines efficiency, ease of use, innovation and safety. In addition, the inverter enables 24/7 monitoring and control, which can even be done remotely via Bluetooth if desired.

Efficiencies increased, costs reduced

Ellis Whittal-Williams of AMS has worked with Franklin Electric and its strategic partner Geoquip Water Solutions and is thrilled. He says the units are completely reliable and also save a tremendous amount of money. Field reports show that the system saves an average of 40% energy compared to conventional speed control systems.

>> It is important to have a system that can handle a demand for very small, slow amounts of water when the birds are very young and allow them to gradually increase flow and pressure as the demand increases.  When the sun comes up and the birds wake up, the demand for water is higher. With the Drive-Tech MINI, we can run the pump constantly instead of stopping and starting it several times an hour. The pressure remains constant, resulting in smoother operation with less wear and tear and higher energy efficiency. <<
