Which motor is most suitable for electric traction work?

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 type of motor is used in traction system?

Traditionally, these were series-wound brushed DC motors, usually running on approximately 600 volts. The availability of high-powered semiconductors (thyristors and the IGBT) has now made practical the use of much simpler, higher-reliability AC induction motors known as asynchronous traction motors.

Which type of DC motor is used for electric traction?

1. DC shunt motor is a constant speed motor but for traction purpose, the speed of the motor should vary with service conditions. 2. In case of DC shunt motor, the power output is independent of speed and is proportional to torque.

Which motor is most suitable for electric traction Mcq?

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.

Which traction system is best?

In case of heavy trains that require frequent and rapid accelerations, DC traction motors are better choice as compared AC motors. DC train consumes less energy compared to AC unit for operating same service conditions.

Which motor is used in electric train in India?

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.

Why is electric traction preferred?

Electric traction involves the use of electricity at some stage or all the stages of locomotive movement. … It has many advantages over non-electric traction systems such as more clean and easy to handle, no need of coal and water, easy speed control, high efficiency, low maintenance and running costs, etc.
