Thrust ripple reduction based on auxiliary-slot permanent magnet synchronous linear motors
Advances in Mechanical EngineeringPermanent magnet synchronous linear motor (PMSLM) has the advantages of simple mechanical structure and high thrust density. However, the simultaneous existence of end effect and cogging force aggravates the thrust ripple and affects the output ...
