The new RPM XE motor platform can provide substantial energy savings and performance for most centrifugal load applications. It achieves efficiency performance two to four efficiency bands above NEMA Premium efficient levels (IE3) by utilizing a hybrid motor design. That design exceeds premium efficiency performance on sine wave power while meeting IE3 as a combined motor and drive package. The motor starts like a traditional design B induction motor and pulls into true synchronous speed and operates as a true synchronous machine. Laminated finned frame construction also contributes to power density and enhanced thermal performance by providing greater heat dissipation, which results in cooler operation and longer motor life. The operating temperature is lower than typical B and F rise temperatures found in the traditional cast iron or steel band induction motors.
