Comparative Study of Linear Primary Permanent-Magnet Vernier Machine and Conventional Linear Permanent-Magnet Machine

This paper presents the comparative analysis of the performance between the linear primary permanent magnet vernier machine and conventional linear permanent magnet machine. Through finite element analysis, the configurations and their performances such as back electromagnetic force and average thrust force are analyzed. The results show that the linear primary permanent magnet vernier machine possess higher thrust force and efficiency than the conventional linear permanent magnet machine. Finally, experiments are carried out for verification.
