Optimum Design of a Three-Phase Permanent Magnet Synchronous Motor for industrial applications

Permanent Magnet Synchronous Motors (PMSMs) have been widely used in many industrial applications. In This paper a new method for multi objective optimal design of a permanent magnet synchronous motor (PMSMs) with surface mounted permanent magnet rotor is presented to achieve maximum efficiency and power density using a Bees algorithm for industrial applications. The objective function is a combination of power density and efficiency to be maximized simultaneously. A particular optimal machine is chosen and its performances are validated with FE analysis. The design optimization results in a motor with great improvement regarding the original motor.
