Abstract：According to high power permanent magnet synchronous motor(PMSM) characteristics of low rotational inertia, high power density and short-time duty type, the paper presents reasonable selection of stator winding forms and coordination of slots and poles, and determines the basic size of motor. The motor shows high electrical performance with finite element analysis of the electromagnetic field. Temperature rise of the motor is serious due to its high power density, slender electromagnetic effective fraction and high rotational speed. On the basis of heat transfer theory, the solving model of 3D transient temperature field for PMSM is established and surface heat transfer coefficients are given. Stator winding copper loss, stator core iron loss, permanent magnet eddy loss and eddy loss in the rotor sheath are obtained by finite element analysis. Wire in stator slot and end region is equivalent into several heat conductors which distributed and arranged respectively, and more reliable 3D transient temperature distribution is obtained. Experimental results show that the design of motor is reasonable.
