Simulation of Permanent Magnet Synchronous Motor for Electric Vehicle Indirect-Torque Control System

Abstract:

For the request of electric vehicle on drive motor, the permanent magnet synchronous motor (PMSM) get more and more attention by its small size and torque characteristics. By analyzing the traction motor characteristics with a constant torque starting and constant power operation, the space vector pulse width modulation (SVPWM) algorithm is used to replace the switching table for direct torque control (DTC) strategy. By analyzing the mathematical model of the PMSM, for the existence of permanent magnets, the rotor coordinate system is applied when calculating the stator flux. Meanwhile, the electric vehicle starting block and the brake block are simulated for the characteristics of that walk namely stop. The results show that the speed has a smooth transition and the torque has a quick response.
