IE4 Highly Efficient Permanent Magnet Synchronous Motor

The IE4 motors lie in the IE4 class of the international efficiency standard. The output of the IE4 motors is 2.2kW to 230kW. The poles for the IE4 motors are 2, 4, 6, and 8. The speed range of the IE4 motors is from 750rpm to 3600rpm.A permanent-magnet synchronous motor (PMSM) uses permanent magnets embedded in the steel rotor to create a constant magnetic field. The stator carries windings connected to an AC supply to produce a rotating magnetic field (as in an asynchronous motor).
