Electric Traction Motor Control System

3 phase permanent magnet synchronous machine pmsm control electronics.

Electric traction motor control system.

The tm4 co150 is a flexible traction auxiliary inverter compatible with permanent magnet and ac induction motors. Main engine and generator. 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. Zytek have developed a high power compact electric drive package comprising.

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. 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. Metadyne control of traction motor.

Suitable speed torque characteristics motor should have a speed torque curve similar to that of traction load. Electric traction means using the electric power for traction system i e. Now let s check out the layout of the locomotive. The electric traction system is the most efficient of all other traction system such as steam and internal combustion ic engine type systems.

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. 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. They converts the input electrical energy into the form as required by the motors. The metadyne control system is based on constant current system of speed control.

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. For railways trams trolleys etc. How does electric traction work. 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. It can be used as a traction motor controller or as an auxiliary power supply in commercial vehicle applications. Electric traction drive system.
