Starting of permanent magnet synchronous motor supplied from PWM inverter

The paper presents the results of starting calculations for a selected model of the surface mount permanent magnet synchronous motor (SMPMSM) supplied from PWM inverter. The calculations were performed using the finite-element method in a field-circuit model of the motor. The calculations of synchronous starting were performed for U/f = constant and linear change of frequency during starting. The influence of initial value of the stator voltage (f=0Hz) on waveforms of the basic quantities during starting has been investigated
