The slotless topology in the bearingless PM slice motor with five-phase was introduced, the structural advantages and operating principle were analyzed. Finite element modeling( FEM) was used to analyze and compare the influence of parameters including magnetizing method, thickness of the PM, air gap length on capability. The simulation results validated that the optimization had a better performance in reducing disturbance of air flux density and torque. Thus, the suspending performance was improved. By utilizing the loss model of conventional motor, the simulation was conducted to get an analysis of the influence of suspension on the loss distribution. And the output efficiency, which was 81. 67% ,was got according to the output torque.
