Abstract
The paper presents a simulation circuit in Simulink of 2.2. kW synchronous permanent magnet motor, supplied
by pulse width inverter (PWM inverter) with two closed control loops per rotor angle and motor current. The
various motor operating regimes are simulated at and above the rated speed and with different step loads. The
obtained results present the motor normal operation with rated speed and load as well as its operation above the
rated speed where the effect of the field weakening can be observed. At higher speeds, the torque is considerably
reduced and in the case of rated load at higher speeds, the motor cannot maintain the synchronism. Besides motor
speed, motor current, torque, and output voltage from the inverter can be analyzed, from the simulation results.
The analysed control scheme is useful for the analysis of motor operation at various speeds.
