Speed Control Of IPSMS Using Space Vector PWM

The permanent magnet synchronous motor is highly efficient and smaller in size compared to other motors. Therefore, this type of motor has recently been widely used in industry, especially in the field of electric transportation. Permanent magnets produce a constant flux linkage component, while excitation coils create a variable flux linkage. Excitation coils can either increase or decrease the permanent magnets flux, adding a further degree of freedom in the motor operation control.The control the permanent magnet speed of a three-phase synchronous motor using the space-vector pulse-width modulation method well be explained in this paper. This method is one of the most recent modulation methods currently used in this field. The first section deals with the synchronous motor and its working idea. In the second section, the method of embedding vectors was discussed, as it was explained and how it works. Finally, in the third section, simulation results.
