EFFECT OF DIFFERENT MAGNET MATERIALS ON THE PERFORMANCE OF SURFACE MOUNTED DIRECT DRIVE PMSM
AbstractIn the present study, a 5.5 kW, 22 pole direct drive surface mounted PM synchronous motor (PMSM) has been designed, analyzed and optimized. After an initial design stage, a 3D model of the generator has been created for the finite element analysis. Cogging torque, output power, efficiency and maximum output power parameters have been analyzed for various material of PM magnets (Alnico, Ceramic, SmCo, NdFeB), which can be produced easily by rareearth elements. In the performed analyzes, the best efficiency and the maximum output power value has been obtained on the N50m type magnet material. Furthermore, the lowest cogging torque has been obtained with an Alnico5 type magnet material.
