The ring winding-permanent magnet linear vernier machine(RW-PMLVM)is proposed for the problems of overlapping ends of distributed winding-permanent magnet linear vernier machine(DW-PMLVM)leading to overlong ends,overweight mass and low efficiency.Firstly,the working principle and basic structure of PMLVM are introduced;Then,the average thrust,thrust-weight ratio,efficiency and power factor of the RW-PMLVM are compared with DW-PMLVM based on the finite element analysis;the results show that compared with DW-PMLVM,the winding length of the RW-PMLVM is shortened by 18.7%,the end leakage resistance is reduced by 41.5%,the thrust-to-weight ratio is increased by 19%,the efficiency is increased by 4.2%,and the copper consumption and volume of the machine are reduced,which is more valuable for engineering applications.
