Abstract：Dual-stator permanent magnet synchronous generator (PMSG) features high efficiency, high power-to-volume ratio which will find many applications in series hybrid EV and wind generator, but its special framework make it difficult to design a dual-stator PMSG through the normal electromagnetic design program. In the paper, the dual-stator PMSG is designed by response surface method(RSM) accompanied with the respective designs of the outer and inner PMSGs which constitute the dual-stator one. First, the dual-stator PMSG is introduced and its design considerations are given. Then the procedures to design a dual-stator PMSG through RSM are presented which consist of how to determine the design parameters, objective function, and how to construct and solve the RSM function.At last, an optimal design of dual-stator PMSG is acquired which verified successfully by FEM and prototype experiment in the part II of this paper.
