Which motor is more suitable for electric traction and why?

3. AC Series Motor: 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 motor is more suitable and more efficient for traction purpose?

In this type of traction system, AC series motors are used to produce the propulsion of vehicle. This system uses AC voltages from 15-25KV at a frequency of 16.7 (i.e., 16 2/3) or 25 Hz. This low frequency leads to give better performance and more efficient operation by the series motor.

Which type of motor used in locomotive?

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 induction motors are not suitable for electric traction?

Answers. Three phase induction motor is not suitable for traction purposes because traction motor requires high starting torque, for urban and sub urban lines, the acceleration (speed at starting) should be high and simple speed control is required to start and stop the motor easily.

Why electric traction system is better than non electric traction system?

Advantages; Fewer substations are required. Lighter overhead current supply wire can be used. Reduced weight of support structure.

Which motor is used in electric traction system?

Windings. The DC motor was the mainstay of electric traction drives on electric and diesel-electric locomotives, street-cars/trams and diesel electric drilling rigs for many years. It consists of two parts, a rotating armature and fixed field windings surrounding the rotating armature mounted around a shaft.

Which of the following motor is suitable for electric traction?

Explanation: DC motors are used for traction as, according to the characteristics of DC motors speed is inversely proportional to torque and square of armature current as well, if linear magnetization is concerned. Thus, DC motors are perfectly suitable for traction.

What are advantages of electric traction?

Advantages of Electric Traction Drives Due to high starting torque, it is possible to produce high acceleration rates. Electric locomotives require less maintenance compared to other drives. Supply of power to the locomotive is easier through the traction substations.

What are the advantages of traction?

The main advantage of a traction lift is its higher speed compared with the hydraulic variety. This means the traction system can be used in tall, modern, 21st-century buildings. The ride in a traction elevator is also smoother.
