Which Motor Is Used In Electric Traction. High starting torque capability of the dc series motor makes it a suitable option for traction application. The engine speed is normally controlled by a load regulator which loads the engine according to the controller setting.
The reason for the term is that the outer rotor is straight off connected with the wheels. For ac series motors, the operating voltage is limited to 300 v.
We Will Be Comparing The Characteristics And See Which Traction Motor You Need To Use In Your Next Electric Vehicle.
Electric traction power systems utilisation of electrical power.
There Is No Requirement For An External Gear System For Such Motors.
Another name of this type of ev motor is the hub motor.
The Weight Of An Ac Series Motor Is About 1.5 To 2 Times That Of A Dc Series Motor.

The Voltage Of The Generator Is Thus Under Control And This Form Of Control Makes Unnecessary Resistance Grids In The Main Motor Circuits To Protect The Traction Motors In Starting And Accelerating.
Generally, the motors used in the traction are asynchronous motors as the torque of these motors varies because of speed variation.
The Series Motor Is Amenable To Simple Speed Control Methods.
There is no requirement for an external gear system for such motors.
Due To Poor Power Factor At Starting, Ac Series Motor Has Low Starting Torque Compared To Dc Motor.
