【Abstract】 On the background of the development trend of energy saving,environmental protection in the automotive industry,analyzed the shortcomings of traditional starter and the research status of integratedstarter-generator( ISG) technology. Then,introduced the topology and operation principle of Flux switching integrated-starter-generator. Take the computational design methods to 7. 5 k W ISG machine for example,this paper presented a theory of flux switching ISG. Also did the electromagnetic field finite element( FEM)analysis on the designed ISG,and verified the feasibility of this method. This paper provided a reference to other scholars. In future studies,the theoretical calculation method can be used to determine the structure and the electromagnetic parameters of ISG,and then be optimized depending on the application.更多还原
