A new type of transverse flux permanent magnet motor with surface-type permanent magnet rotor structure and silicon steel stator structure was designed. According to the new structure of transverse flux permanent magnet motor, the operating principle of the motor was given. The relationship among motor output torque, torque density, magnetic poles and winding parameters are deduced, and a reasonable method of designing motor size parameters was proposed. A three-dimensional finite element model of the motor was created and the model grid division was done using ANSYS finite element analysis software. According to different winding current values and different positions of stator and rotor, the motor magnetic flux density distribution, the output torque and inductance parameter were given through calculating the three dimensional finite element models. Finite element analysis results show that the new motor structure is reasonable.
