We have been studying the aplication of permanent magnet synchronous motor (PMSM) for railway vehicle traction in order to reduce the weight and size of direct drive traction motor. As a part of this study establishing a current control system of PMSM suitable for railway vehicle traction should be investigated.<br>In this paper we discuss about designing method of current control system mentioned above and suggest a method which is available under the condition of railway vehicle traction, low switching frequency and long digital calculating period. Next we investigate how to decide current response time constant <i>T<sub>d</sub></i> and reach a conclusion that it is about 10ms is appropriate under some assumed condition. Then we checked this current control system for railway vehicle traction through experiments and studies of influence of parameter changing. Consequently we can recognize the current control system has satisfactory performance for railway vehicle traction.
