The Pulse Generators or PGs are equipped to detect the rotor frequency of induction traction motors for the torque control in railway vehicle traction field. Eliminating PGs are preferable from the view points of increasing the reliability of the traction system, reduction of the both initial and maintenance cost and down-sizing induction traction motors. Expecting those merits, we have been studying to apply a sensor less control method to induction traction motor control. Prior to some reports of studies and tests to apply speed sensor-less strategy to railway vehicle traction, we lunched the ideas to apply the speed sensor-less control strategy and results of the studies and the tests. In this paper, we present the novel control method for railway vehicle traction and some results of theoretical study and tests.
