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 r… Show more
