Induction motor drive with PWM inverter control, which can reduce the weight of the driving devices, is used for Shinkansen trains in order to achieve high speed transportation.<br>This paper describes the experimental results for controlling wheel slip and re-adhesion at high speed running with the type 953 Shinkansen test train. The induction motor for each axle of this train is individually controlled by an independent PWM inverter. By introducing the vector control for the induction motor drive system, quick response for the motor torque can be achieved when wheels are going to slip. The control scheme for the wheel slip and re-adhesion is that the motor torque is gradually reduced by increasing of wheel slip speed.<br>The results show, it is possible to recover to adhesive condition against wheel slip, without excessive motor torque reduction, when the reducing torque value and control time constant are properly selected.<br>By these tests, re-adhesion characteristics improvement by induction motor vector control are obtained. To the next step, the parallel motor control system with a vector controlled inverter will be investigated.
