With the development of the power era, the position of electric drive in the field of transmission is becoming more and more important. However, from the perspective of economy and other aspects, it is not realistic to realize direct electric drive, so gear plays an important role in this development. Traditional mechanical gears have problems in many aspects and cannot meet the needs of development. Modulated gear is a non-contact magnetic transmission device that can solve the problem of traditional mechanical gears. However, when the start-up and load and speed changes, modulated gears will experience transient oscillations. In order to solve this problem, this paper proposes a dynamic improvement study of modulated magnetic gears with damper winding. Studies have shown that the addition of the damper winding can effectively reduce the time required for the magnetic gear to reach the steady state and the amplitude of the oscillation attenuation, so that the dynamic performance of the entire system can be improved.
