Basically, DC series motors are employed in electrical train
on Traction. It uses DC series Motor because it has high
starting torque and good speed regulation.
Here overhead supply is used 25KV AC. First it step down and
then converted into 750V DC which is applied to DC Series
Motor.(Some area uses 1.5KV DC in overhead)
when a train get start it uses series connection of 2 or 4
series motor. It provide high torque.
After starting, it uses parallel connection for high speed
and less torque
