Traction Motor

 

an electric motor used to drive vehicles such as electric locomotives and trains, diesel-electric locomotives and ships, and streetcars, trolleys, and other electric vehicles. Traction motors may use alternating or direct current, and they may have individual or group electric drive to transmit the torque from the engine shaft to the propulsion mechanism. They also may differ with respect to the cooling system; self-ventilation is used in motors with a power of up to 250 kilowatts, and independent and mixed ventilation are used for more powerful motors (seeCOOLING OF ELECTRIC MACHINES).

DC motors, single-phase AC commutator motors, and three-phase asynchronous motors are most commonly used as traction motors. Sealed traction motors are made for vehicles operating under hazardous explosion conditions. The power of modern traction motors ranges from a few kilowatts to several megawatts.

Consequently, Schaeffler UK decided to investigate whether depot-based vibration measurements, using an underfloor wheel lathe to rotate the wheelset, could be used to assess the condition of the traction motor and gearbox.
Preventing premature failure: a series of studies have shown that depot-based condition monitoring of railway traction motors using underfloor wheel lathes can be implemented at a fraction of the cost of Remote Condition Monitoring, says Dr Steve Lacey, engineering manager at Schaeffler UK
The operational reliability of railway rolling stock, in particular passenger trains, is key in maximising availability and is highly dependent on the health of the drive system--the traction motor and gearbox.
