Electric Traction Motor Control System

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.

Electric traction motor control system.

Electric traction drive system. A traction motor speed control should be easy and simple such that motor can be easily start and stop. Now let s check out the layout of the locomotive. They contain and control the source and motor currents with in permissible limits during the transient operations such as starting braking speed reversal etc.

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. Suitable speed torque characteristics motor should have a speed torque curve similar to that of traction load. The electric traction system is the most efficient of all other traction system such as steam and internal combustion ic engine type systems. It offers several benefits over other systems including quick start and stop very efficient pollution free easy to handle and easy speed control.

The system can also reduce the power of any traction motor whose wheels are slipping. It can be used as a traction motor controller or as an auxiliary power supply in commercial vehicle applications. 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. Main engine and generator.

Metadyne control of traction motor. Electric traction means using the electric power for traction system i e. 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. 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.

The metadyne control system is based on constant current system of speed control. For railways trams trolleys etc. Traction motors are used in electrically powered rail vehicles electric multiple units and other electric vehicles including electric milk floats elevators roller coasters conveyors and trolleybuses as well as vehicles with electrical transmission systems diesel electric locomotives electric hybrid vehicles and battery. 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. How does electric traction work. Zytek have developed a high power compact electric drive package comprising.
