Which type of motor is suitable for electric traction?

Many single phase ac motors have been developed for traction purposes but only compensated series type commutator motor is found to be best suited for traction. Single phase induction motors have been abandoned as they are not capable of developing high starting torque.

Which of the following single phase motor can be used for electric traction?

For electric traction, DC series motors are best suited. DC series motors and AC series motors are very much recommended, as they provide a high starting torque Nowadays three-phase induction motors are also being used.

Do trains run on AC or DC?

DC motors are used on trains is because of their high torque and good speed control. Compared to AC motors, DC motors can provide industry applications with a fine balance of strong starting torque and controllable speed for seamless yet precise performance.

Which DC motor has maximum self relieving property?

Answer : Series motor has got maximum self relieving property.

Which DC motor has maximum self loading property?

Which DC motor has got maximum self-loading property? Explanation: A differentially compound DC motor, flux reduces so sharply at small increase in load at higher values of load.

Which DC motor is generally?

Explanation: DC series motor is used where high starting torque is required, thus in cranes and hoists DC series motor is used widely.
