Abstract：The linear primary permanent magnet vernier (LPPMV) machine, which possesses the advantages of low speed and high thrust force, is very suitable for linear direct-drive applications. Reasonable design of winding arrangement can substantially improve the machine performances. Firstly, four types of winding arrangement were presented for a 6/2 pole LPPMV machine based on the machine operation principle. Secondly, the characteristics of the LPPMV machine with different winding arrangements were analyzed by finite element method, including the no-load EMF and inductance. And the total winding weight, armature current, average thrust force and iron loss were compared in the condition of the same copper loss. Then the efficiency parameters of four winding arrangements were obtained. Finally, one of the winding arrangements was selected to build a LPPMV prototype machine. And the performances of the machine were verified by experiments.
