Abstract: The research on PM brushless starter generator has raised widely attention and has been the study focus in the field of electrical technology for vehicle. A new integrated PM brushless starting generator(S/G) composing of high-performance thulium PM motor and bi-directional converter was proposed in the paper. The converter topology, operating principal, control characteristics of starting and generating operation were discussed in detail. A prototype has been developed to verify the feasibility of the system. The Experimental results show that the proposed system can offer good starting and generating performance. The research results can be used for reference by the developer working on the design and application of new-generation S/G products for motorcycle.
