Abstract

At present, further reducing the mass of permanent magnet brushless dc motor has become a new demand for the development of humanoid robots. In order to achieve this goal, this paper presents a new design idea of motor. Compared with the motor currently used in robots, the new method will reduce the mass of the motor and improve the torque density as well, while ensuring the same torque output. This design method mainly uses HALBACH array for excitation. Through finite element analysis, the distribution rules of magnetic field, back electromotive force, torque and cogging torque of the motor are obtained. Experimental result shows that the actual torque of the motor reaches the goal of our design, and the rotor weight is reduced by 30%.
