wha tis the ac motor used for traction system..

Answer / rohith sathees

Traditionally, these are DC series-wound motors, usually
running on approximately 600 volts. The availability of
high-powered semiconductors (such as thyristors and the
IGBT) has now made practical the use of much simpler,
higher-reliability AC induction motors known as
asynchronous traction motors.

wha tis the ac motor used for traction system..

Answer / rabi

DC series motor is used in traction. DC series motor
produces high torque at low speed, which is required during
starting of train as it (Train) has got high inertia at
starting.
Three phase induction motor is also used in high speed
train e.g. RAJDHANI EXPRESS.
