Abstract: Under a condition that rotor rotation speeds (Ées are equal, winding wire currents Id, Iq are equal, and winding wire inductances Ld, Lq are equal in first and second electric motors 1, 2, a magnet temperature anomaly detector 30 provided in a microcomputer 5 calculates a change ratio d(|¦ml-¦mr - ¦mr|)/dt of a magnetic flux difference between the first and second electric motors 1, 2 based on the difference Vql* - Vqr* between a q-axis voltage command value Vqr* corresponding to the first electric motor 1 and a q-axis voltage command value Vqr corresponding to the second electric motor 2, and then when the change ratio d(|¦ml - ¦mr|)/dt of the magnetic flux difference is more than a predetermined threshold Sh1, it is determined that a permanent magnet of at least any one of the electric motors 1, 2 has a temperature anomaly.

Abstract: Provided is a controlling device for a railway electric car, the controlling device being able to detect a slipping/sliding phenomenon during, in particular, high-speed travel and to exercise slipping/sliding control in an appropriate manner. A slip controlling unit 1 includes a first adhesion level index generating unit and a second adhesion level index generating unit. In a normal slipping state in which an acceleration changes instantaneously, torque control is exercised by using a first adhesion level index generated by the first adhesion level index generating unit based on an acceleration deviation and a speed deviation. In a slipping state during high-speed travel, because the acceleration deviation and the speed deviation are small, torque control is exercised by using a second adhesion level index generated by multiplying the first adhesion level index by a gain equal to or smaller than 1 generated by the second adhesion level index generating unit.
