Study of Optimal Design of Surface Permanent Magnet Motors

Akira YAMAMOTO


Permanent magnet motors are used for various purposes because of their high performance and compactness. However, the performance that is required of them is different for each application, and there are times when they must simultaneously serve in multiple capacities. While there are some reports on the optimization of a motor's design for its required performance, it is necessary to demonstrate the basic principles of motor design, and particularly the effect of the stator and the rotor shape on performance. In this report, we shall set the basic dimensions of the rotor and the stator as factors of Design of Examination (DOE) and analyze them by FEM. As a result, we shall present the effects of each factor on performance and optimal design.
