Abstract

Magnetic gear is becoming attractive due to the features such as low acoustic noise, maintenance-free, improved reliability, precise peak torque transmission capability, and inherent overload protection. This paper presents a highperformance linear permanent magnet (PM) gear which can transmit force to a closed space conveniently meanwhile change the moving velocity. 2-D finite element analysis (FEA) is employed to investigate the performance of such a PM gear. Simulation result shows that the transmit thrust force of the studied linear PM gear can exceeds 200 N.
