We have been investigating to apply permanent magnet synchronous motors (PMSMs) to railway vehicle traction, because the efficiency of PMSMs are higher than that of induction motors and they are expected to enable the traction motor down sized. We have to consider peculiarity on the railway vehicle traction when we design the electrical constants of PMSMs. On this paper, we point out the particular points which we have to take into account on designing works and analyze how the constants of PMSMs affect the their performance. Through this study, we suggest how to design the constants and applied the method to assumed designing works to verify the method. We conclude that the suggested method is available for the designing of PMSMs’ constants and reluctance torque is essential to the performance PMSMs for railway vehicle traction purpose.
