The PMS motor offers considerably improved efficiency over induction motors, even under partial load conditions; and extremely high efficiency under rated operating conditions. They also have considerably higher power density, which, for geared motors, yields higher system efficiency with minimal installation volume – and also reduced weight.
PMS motor drives can produce higher torques for the same installation volume as conventional induction motors, allowing a smaller motor size to be specified for some applications.
Bauer's PMS motors are available in ventilated and non-ventilated configurations across the power range from 0.55kW to 15kW. They operate on 380V to 500 V power supplies, and are rated for inverter duty, offering an extended speed range with constant torque.
