Core Loss Reduction of an Interior Permanent-Magnet Synchronous Motor Using Amorphous Stator Core

The core losses of an interior permanent-magnet synchronous motor (PMSM) have been reduced by about 50% using an amorphous magnetic material (AMM) stator core instead of a nonoriented (NO) steel stator core. Numerical calculation and experimental tests data have been compared to evaluate the reliabi...

Description
Summary:The core losses of an interior permanent-magnet synchronous motor (PMSM) have been reduced by about 50% using an amorphous magnetic material (AMM) stator core instead of a nonoriented (NO) steel stator core. Numerical calculation and experimental tests data have been compared to evaluate the reliability of the results. The AMM stator core has been realized using the latest improvements in manufacturing technologies.
