The growth in the market of PM motor drives has demanded the need of simulation tools capable of handling motor drive simulations it is important to simulate the inverter fed PMSM drive system so that its characteristics under steady state, transient and abnormal conditions can be predicted. This paper presents the details of the Simulink model of permanent magnet synchronous motor drive system. A control circuit employing pulse width modulation technique has been designed such that the PMSM runs at constant speed irrespective of the load torque applied on it. The performance of the motor is tested for different load torques and the speed is observed to follow the reference speed.
