This submersible motor features permanent-magnet technology

The new Pleuger PMM6 is a submersible electric motor that utilizes permanent-magnet technology. This electric, three-phase induction motor is an alternative to asynchronous designs, providing lower thermal losses and higher efficiency at both full and partial loads, says the company. Also featuring a large, air-gap configuration, the Pleuger PMM6 is currently available in a 150-mm motor size with a power output of 5–45 kW. Additional sizes are planned for future release. Operated in conjunction with variable-frequency drives, the motor runs at synchronous speed with no rotor losses, which allows pumps to run efficiently under variable flow conditions. — Flowserve Corp., Irving, Tex.
