摘　　要：外转子双凸极永磁电机的绕组所匝链的磁链、绕组自感以及气隙磁密分布等静态特性是电机性能分析、设计的基础。它决定了电机的稳态特性。而电机的稳态特性与电机结构有着密切相关的联系。该文在有限元方法的基础上分析了不同气隙和转子极弧参数对电机静态、稳态特性的影响。为该类电机的设计和进一步研究提供了依据。The static characteristics of ERDSPM such as winding turn chain flux、winding self-inductance and air-gap flux density distribution is the basic of analysis the performance of motor and design it.It determines the steady-state characteristics of motor.The steady-state characteristics of motor was close conneted with motor structure.In the paper,finite element method was used as baisc to analysis static and steady-state characteristics of motor at different width air-gap and rotor pole radian.
