The characteristics of linear motor with function of linear transformer for a future wireless light rail vehicle (LRV) are studied analytically by using the two types of numerical analyses. The dynamic characteristics in running condition are cleared. It is confirmed that the special motor has the satisfied thrust. The waveform of line current in the commercial source power on ground can be sinusoidal when the current of onboard winding is controlled sinusoidal. On this motor, the handling power of winding is in proportion to the pole pitch if the resistive loss of winding is neglected. As a merit, the full regenerating brake can be used at full speed.
