Optimal Design of Transverse Flux Permanent Motor with Reducing Cogging Torque

Abstract

Transverse Flux Permanent-magnet Motor has low speed, high torque density characteristics. In order to reduce cogging torque, a novel topology model of transverse flux motor has been designed for electric vehicle wheel in this paper. Its remarkable characteristic is sufficient to reduce the cogging torque, raise motor output torque and raise utilization ratio to the space in electric vehicle wheel. The cogging torque of the prototype model is calculated through the three dimensional finite element analysis methods. The result shows that the theoretical research method is effective and topology model rationality.
