Abstract: In order to keep the motor volume and slot number unchanged as well as reduce the motor speed, a new type of linear permanent magnet vernier motor (LPMVM) is discussed. The characteristics of LPMVM are simple structure, low speed, and reduced thrust ripple. According to the air-gap permeance about slots only on the stator and the formulas of flux density with no-load EMF, the thrust are analyzed, and the motor structure is given. Its steady performances, compared with the traditional permanent magnet linear synchronous motor (PMLSM), are simulated by using the finite element method (FEM) as compared with the traditional permanent magnet linear synchronous motor (PMLSM). The results show that it has a good performance in a low speed, especially since the detent force is very small, so it is suitable for the low-speed direct-drive system.
