becoz of high starting torqe to move train
speed control of dc motor is more easy as compare to any ac motor..and power
operation of dc motor(s/t) is simple
Series motors are capable of taking huge starting torque like those of trains (traction)
DC series motor can provide large starting torque.
it is a motopr which is used to drive the electrical vehicles
DC Motor :- SHUNT MOTOR, Series Motor, Compund Motor, ( mainly used in traction system only. as there performanace is very poor & DC supply is not available easily so there uses is less then AC motors,) AC Motor:- Induction Motor ( Slip ring Type, squrrile cage Induction motor) Syncronous Motor.
An electric train uses electric motors. Modern trains have many motors, they are mounted on the axles, one motor per axle. Some axles will be powered and have motors on them, some will not.
the method can not be used in the case of a d.c series motor
A relay cannot be used to power a motor. It can be used to control the motor by wiring the motor circuit in series with the relay contacts.
dc series motor is used for traction...
DC series motors...
traction means propulsion of vichel and traction motor means the motor which propel the our object and it have tractive effort thats why we are saying traction and it is used in railways
DC Traction Motor.
