Thanks to the progress in power electronics and advanced control technologies, the traction motor for the electric railway vehicles has changed from the DC motor to the induction motor. This has brought about a compact size, light weight and maintenance-free configuration, and there has been a growing need for further advance in this direction. Then, we developed the main circuit system using the Permanent magnet assisted Reluctance Motor, and have conducted a running test on the series E231 train-set. As the result, the PRM was suitable for a traction motor for railway vehicles.
