permanent magnet synchronous motor

Hybrid Taguchi genetic algorithm（ HTGA） is introduced in the optimal design of a PM motor in this paper. HTGA gains local optimization ability from Taguchi,and gets global optimization ability from traditional GA.As a result,it can find the solution to the problem faster and more precisely. Successfully applying HTGA to optimization design can save a lot of computing time,shorten the development cycle and reduce the labor intensity of designers. Offspring individuals of GA are generated by Taguchi method,so as to make sure that the stronger offspring characters can be inherited,which enhances the robustness of motor performance. A mathematical model of PM motor is established in this paper,and the optimization algorithm is combined with a basic electromagnetic design program of PM motor. The optimization design program is applied to a PM motor electromagnetic design,and calculation results show that properly applying HTGA in motor design process can achieve good optimization effects.
