Abstract: 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.
