Answer / 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.

Answer / rajesh.b.jadav
d.c series motor as it has a high starting torque
characteristics

kongrates 2 all.. hu said dc series motor.
since the starting torque is very high, obviously this motor
is widely used for traction purposes..
the ratings of komn dc series mtr used for traction is,,
750v dc
650A
the gear ratio is 63:17
each locomotive (train engine)consists 6 such motors.

Answer / glinto francis
dc series motor becouse high starting torque.this type of
motor is suitable for traction purpose.

Answer / sanjay dalvi
Dc series motor is used because it have characteristic of
HIGH STARTING TORQUE IT PICKS UP LOAD WITH CONSTANT SPEED.

Answer / ipsa
obviously d.c series motor used in train,hoist,conveyer etc
due to its high starting torque.
| Is This Answer Correct ? | 20 Yes | 1 No |
Answer / k.prakashchandra
Series motor while starting is OK. But how to vary the speed
while running ? Is change over to shunt connection done ?

Answer / ramasamyseenu
in the engine side it uses two dc series motor and one 3phase induction motor and the purpose of dc motor is to give high starting current and to make the locomotive to move and to overcome the inertia offered during motion. The purpose of dc series motor is also to perform regenerative braking with 3phase induction motor. The purpose of three phase induction motor is to operate the engine in constant speed.
The motors which are connected below the train compartments are dc series motor it also complements the motion of train from rest thus by reducing load on the train.
