Performance tests are carried out to demonstrate the superiority of a permanent magnet synchronous motor to an induction motor as a traction motor for high-speed train. A prototype motor was manufactured by replacing the rotor of a conventional induction motor. The test results show that the permanent magnet motor is lighter, efficient and more silent than the induction motor because of the different rotor structure.

We are developing a new high performance traction motor for railway vehicle using interior permanent magnet synchronous motor (IPMSM) and expecting it can reduce energy consumption. To estimate the losses and energy consumption of IPMSM, a simple motor model is needed. In this paper, We propose a simple equivalent circuit and loss model for IPMSM, the constants of which can be obtained from several simple test results. The calculation results using them show that the total loss of the IPMSM becomes about 60% of that of the induction motor when used as a traction motor for a typical commuter train.
