摘要
A method for detecting a slipped traction motor pinion in a locomotive is disclosed. The locomotive may have a traction system and a controller in communication with the traction system. The traction system may have a wheel axle, a traction motor operatively connected to the wheel axle, a speed sensor associated with the traction motor, an inverter coupled to the traction motor, and a current sensor associated with the inverter. The method may include monitoring signals indicative of a speed of the traction motor received from the speed sensor, receiving current feedback associated with the inverter received from the current sensor, comparing the signals from the speed sensor to the current feedback, and determining that the traction motor is decoupled from the wheel axle based on the comparison of the signals from the speed sensor to the current feedback.
