Abstract

Abstract: With the increasing demand for transmission efficiency and reliability of special vehicles in the future，electric transmission will become an important development direction of the future transmission，and the electromagnetic optimization design of magnetic gears is one of the key technologies in the research and development of new electric transmission in the future. The transmission principle of coaxial magnetic field modulated magnetic gear is analyzed，the analytical equation of magnetic gears is established，and an electromagnetic optimization design method of magnetic gear based on Taguchi method and multi-target robust optimization algorithm is proposed. The speed and torque characteristics of magnetic gears prototype were tested in typical operating conditions. The results show that the transmission ratio is stabilized at 6.67，the output torque is 359.7 N·m，the output power is 56.49 kW，and the efficiency is 98.1%. The torque performance and efficiency achieve the optimization design targets.The electromagnetic optimization design method was verified through experiment.
