Abstract

The purpose of this paper is to describe a theory study of the linear stator permanent magnet vernier (LSPMV) machine. The fundamental operating principle, design criteria, characteristics and performances of the machine are discussed in this paper. In order to confirm the advantages, a quantitative comparison between the LSPMV machine and the linear vernier hybrid (LVH) machine is performed under the conditions of the same magnetic loading, electric loading and rated speed by using the finite element method. The results show that the proposed machine has higher power density and lower cogging force than the LVH machine.
