Abstract :
Reduction of permanent magnet materials is of interest to many designers as cost of rare earth increasing. In the paper, it is studied 20 % reduction of magnet size by optimizing shape of the magnets in Interior Permanent Magnet Synchronous Motor (IPMSM) and the aims to maintain the high efficiency map over the operating region. Finally, the Finite Element Method (FEM) Simulation result is verified by the testing.
