Permanent magnet technology in submersible motors

Franklin Electric is the Pioneer in Permanent magnet technology in submersible motors. For more than 10 years, our High Efficiency systems with PM technology have been achieving efficiencies up to 94 % and have proven around the globe.

The key factor for the superior efficiency is the permanent magnet rotor design with buried magnets. Thanks to the excellent partial load behavior and less temperature heat rise, outstanding improvements in the motor efficiency are achieved. The total rotor losses of a permanent magnet motor are eliminated. The synchronous motor requires lower Amps to run at the same pump load.

The synchronous motor has less temperature heat rise. The synchronous motor has a lower weight and a reduced length compared to an asynchronous motor.

Perfectly matching components guarantee first-class performance and efficiency. A setup wizard guides step-by-step through the drive settings, making setup easy. The operation with a variable frequency drive significantly improves the efficiency and allows to set up and control the system remotely.
