Abstract: The design and simulation of a kind of PMSM with high power density was introduced, which was used in the drive system of pipe detection robot. In this system the motor adopt proper design and simulation to realize low cogging torque rotation. Compact structure design was used to insure the volume demand of pipe detection. Heat sinking design was adopted to insure the reliable performance of the motor system in the very high temperature environment.
