which motor is used in electric train...???????
Answer Posted / mrityunjoy
dc series motor
reason:- In trains there are many comartments full of
passengers,so during the starting it requires high starting
torque and in dc series motor torque T proportional to Ia
square and Ia=If,so if the motor started without any load
then the armature current will be very high which may
damage the motor.
