A railway vehicle equipped with a rotating electric machine is provided with: a voltage output device that outputs a drive voltage to the rotating electric machine in order to stabilize a control system even during idle running or slip and to detect idle running or slip in advance; a current detector that detects a current flowing in the rotating electrical machine; and a control device that estimates and calculates the angular velocity of the rotor of the rotating electric machine, the control device calculates a compensation value that corrects a state quantity that is an input for estimating and calculating the angular velocity in order to suppress, to approximately zero, a stability deviation that occurs in the state quantity during acceleration and deceleration of the rotating electric machine. When the compensation value exceeds a predetermined value, idle running or slipping of the drive wheel driven by the rotating electric machine is detected.
在搭载旋转电机的铁道车辆中,具有:电压输出装置,其为了在空转或打滑时也使控制系统稳定化,并且提前检知空转或打滑,而向旋转电机输出驱动电压;电流检测器,其检测在旋转电机中流动的电流;以及控制装置,其推定运算旋转电机的转子的角速度,控制装置为了将在旋转电机的加减速中成为用于推定运算角速度的输入的状态量中产生的稳定偏差抑制为大致零,而运算对该状态量进行校正的补偿值,在补偿值超过规定值的情况下,检知由旋转电机驱动的驱动轮的空转或打滑。
