Analysis of Linear Primary Permanent Magnet Vernier Machine Using Finite element method

In this paper, Modeling and analysis of Linear Primary Permanent Magnet Vernier Machine (LPPV) is presented. Since both armature windings and permanent magnet (PM) arrays are located on primary of the machine, this type of Vernier machines is classified as flux reversal machines. Vernier effect and flux reversal operation lead to high force density in the machine. Simple the translator structure in the machine is suitable for machines with long distance rail. Firstly, operation principle and geometric structure of the machine is presented. Then, 2D and 3D Time Stepping Finite Element Method (TS-FEM) are utilized for performance evaluation of the machine. Finally, the quality of the no-load flux linkage, no-load ElectroMotive Force(EMF), thrust and normal forces, the self and mutual inductances and the output power of the machine at no-load and loading condition are discussed and analyzed.
