英语翻译随着能源使用紧张,生态环境等问题的日益突出,汽车行业面临新的挑战.因此混合动力电动汽车应运而生,它以高能量密度的

As energy use nervous, and the ecological environment is becoming increasingly conspicuous, the problems of the automobile industry is facing new challenges. So a hybrid electric vehicle, it emerged with high energy density fuel as a key driver in a clean energy and convenient for auxiliary power energy, shirt-sleeve fuel cars and pure electric vehicles, is most has the advantages of the market value of the low emission and low oil consumption car. Drive motor and its control system is the power system of electric vehicle in the core part. The Permanent magnet synchronous motor (range, "which synchronous're new all-digital fuzzy) has the high efficiency, high power density characteristics in the application of the electric car more and more. This paper is the content of hybrid electric vehicle design of permanent magnet synchronous motor. In this article, the design method based on the magnetic circuit in the design calculation, the two options, and the two schemes are analyzed. Finally and magnetic circuit design parameters of results and is a calculate results were compared in order to verify the rationality of the design parameters, in addition to the design requirements main performance indexes of simulation show that the design scheme is feasible.
