摘要：
Aiming at the problems of high cost and operational risk at low speed and high torque output for traditional direct drive motors, a low speed large torque permanent magnet motor is proposed. Compared with the traditional vernier motor, the double stator and intermediate rotor were adoped. Both the inner and outer stator teeth have the function of magnetic flux modulation. The poles of the rotor facing the air gap on both sides and the magnet were utilized. The working principle and the design method of the motor were introduced. The detailed design parameters, structure and assembly diagrams were given. The structural parameters such as the width and height of the inner and outer teeth and their matching which are closely related to the motor performance were optimized. The 2D model of the motor was established and the finite element method was used to analyze the performance of the motor, such as cogging torque, output torque, no-load back electromotive force, air gap flux density and so on. The simulation results validate the correctness of theoretical analysis. © 2019, Harbin University of Science and Technology Publication. All right reserved.
