Research on Tubular Linear Permanent Magnet Vernier Motor for Automobile Active Electromagnetic Suspension

The active electromagnetic suspension is characterized by fast response speed, simple structure and high control accuracy, which ensures the good performance and makes it a research hotspot. Tubular linear permanent magnet vernier motor (TLPMVM) can meet the requirements of high thrust density and low thrust ripple of active electromagnetic suspension system. By comparing the performance of TLPMVM with different topologies, this paper finds out the motor structure scheme suitable for active electromagnetic suspension.
