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 integratedstartergenerator(ISG) technology. Then, introduced the topology and operation principle of Flux switching integratedstartergenerator. Take the computational design methods to 75 kW 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.
