The necessity of maintenance for locomotive traction motor parts . Traction motors for locomotives play a crucial part in the rail industry, and they must be well-maintained and in good working order to avoid underperformance or sudden breakdowns.. Our company has extensive rail industry expertise, including emergency …
A conventional railway vehicle adopts the rigid-axle wheelset (RW) due to its inherently characteristics of automatic restoration capability without additional actuators or control. RW allows the railway vehicle to run to the center of the rail. However, there is no restoring force in independently rotating wheelsets (IRWs), if only traction torque control is …
A traction motor is basically an electric motor that generates the power to rotate the wheels of the train. The rotating force produced by the traction motor is transmitted to the wheels of the vehicle through the pinion and gear wheel. The various types of traction motors used are, DC Series Motor, AC Series Motor, Three Phase …

The sand dramatically increases the traction of the drive wheels. The train has an electronic traction-control system that automatically starts the sand sprayers when the wheels slip or when the engineer makes an emergency stop. The system can also reduce the power of any traction motor whose wheels are slipping.
Electric railway traction for rapid urban/suburban transportation, as well as for high-power and long-distance applications, has a history from end of the 19th century. ... as well as being integrated in …
This paper presents high-efficiency technology for railway-vehicle traction motors, looking at the latest development of induction motors (IMs) and permanent magnet synchronous motors (PMSMs). A proposed high-efficiency IM realized decrease in stray load loss and harmonic losses as well as fundamental loss, where the magnetic wedges inserted into …
Cylindrical roller bearings used in traction motors for railway vehicles are used at high rotational speeds and under light loads. Under these operating conditions, the life due to cage wear is much shorter than the life due to raceway fatigue. Therefore, bearing life can be extended by reducing cage wear. The authors thought that to reduce …
Hence, the cage defect of Railway Traction Motor Bearing (RTMB) is usually difficult to be recognized with motor housing vibration acceleration signal. Considering Induction Motor (IM) itself a sensor, the mechanical imbalance of bearing cage defect can reflect in stator current through the motor gap magnetic field rather than a …
