SIMULATION OF INVERTER- PERMANENT MAGNET SYNCHRONOUS MOTOR SYSTEM USING RESOLVER SENSOR BY PSIM

Abstract

The position of rotor is necessary for achieving the vector control system of Permanent Magnet Synchronous Motor (PMSM). The focus of this paper is using the resolver sensor to detect the rotor position of PMSM. The advantages of this sensor are its robust structure and noise insensitivity. The resolver algorithm is proposed and implemented in the vector control system of PMSM. The diagram of proposed current and speed control loop was verified by PSIM software,proving the effectiveness of this method.
