Electric Traction Motor Control System

Electric traction means using the electric power for traction system i e.

Electric traction motor control system.

The electric traction system is the most efficient of all other traction system such as steam and internal combustion ic engine type systems. It can be used as a traction motor controller or as an auxiliary power supply in commercial vehicle applications. Now let s check out the layout of the locomotive. Metadyne control of traction motor.

It offers several benefits over other systems including quick start and stop very efficient pollution free easy to handle and easy speed control. In resistance control or series parallel control a great deal of energy is dissipated in the starting resistance and jerks are experienced when the controller of the starter moves from one position to another position. Electric traction drive system. Integrated concentric gearbox optional the powertrain is intended for use in electric and hybrid vehicles using a vehicle controller high voltage battery and other supplementary systems supplied by the customer.

The train has an electronic traction control system that automatically starts the sand sprayers when the wheels slip or when the engineer makes an emergency stop. The tm4 co150 is a flexible traction auxiliary inverter compatible with permanent magnet and ac induction motors. Now a day magnetic traction is also used for bullet trains. They contain and control the source and motor currents with in permissible limits during the transient operations such as starting braking speed reversal etc.

Zytek have developed a high power compact electric drive package comprising. Main engine and generator. However due to low tc of nd 2 fe 14 b 315 c the nd fe b based sintered magnets cannot be used as their hc falls rapidly with temperature. A traction motor speed control should be easy and simple such that motor can be easily start and stop.

Operating temperature of traction motors for hybrid electric vehicles is generally 150 200 c and they demand at least 6 koe 0 6 t of hc. Suitable speed torque characteristics motor should have a speed torque curve similar to that of traction load. The metadyne control system is based on constant current system of speed control. How does electric traction work.

A traction motor is an electric motor used for propulsion of a vehicle such as locomotives electric or hydrogen vehicles elevators or electric multiple unit. They converts the input electrical energy into the form as required by the motors. The system can also reduce the power of any traction motor whose wheels are slipping.
