8" Rewindable Permanent Magnet Motors
8" Rewindable Permanent Magnet Motors
The 8" Synchronous rewindable motor is characterized by up to 8% (system up to 11 %) efficiency. The submersible motor’s permanent magnet equipped rotor eliminates rotor losses thus significantly reducing motor current and heat rise. In many cases, reduced motor current equals less drop cable cross sectional area further reducing overall installation cost. Excellent partial-load efficiency of permanent magnet motors allows the entire power range to be covered with only a few different motor sizes, thus offering important stock-keeping advantages.
A special diaphragm ensures pressure compensation inside the motor. The Sandfighter® SiC seal system is standard. For applications in aggressive media, motors made of 316SS and 904L are available.
