Abstract: The design method on line-start permanent magnet synchronous motor with fractional-slot was introduced, the problems should be paid attention to on fractional-slot windings，permanent magnet and stator or rotor designing were discussed,and the parameters of the motor with magnetic circuit calculation were analyzed based on magnetic circuit analysis software Ansoft’s RMxprt.A more accurate motor model of fractional-slot was designed and built.The major researching on the effect to the motor performance with rotor damp slot dimension provided a reliable reference for optimal design of permanent magnet motor with fractional-slot winding.
