Study on starting and braking characteristics of permanent magnet synchronous traction motor

Firstly, the basic principle of space vector pulse width modulation (SVPWM) technology is introduced simply in this paper. Then, simulation model of permanent magnet synchronous traction motor control system is established based on MATLAB/Simulink. The starting and braking characteristics simulation results show that the model is effective, as well as the PI adjuster parameters is appropriate. The simulation model and method provides a base for both software and hardware design of an actual control system of permanent magnet synchronous traction motor.
