Design and analysis of open loop model of a Permanent Magnet Synchronous Motor (PMSM) drive

This paper presents the development of an open loop model of a Permanent Magnet Synchronous Motor (PMSM) drive fed from a 3 phase bridge inverter and operating under self-control mode with the rotor position information. Permanent Magnet Synchronous Motors (PMSM) are widely used in AC servo drives because of its high torque to inertia ratio, high power density, high efficiency and power factor as compared to other conventional drive motors. The different performance indices of the system like speed, electromagnetic torque, phase voltage, phase current, rotor position etc. have been executed in MATLAB environment.
