“…The practical significance of the work is that with a single frequency converter, the rotational speed of the resulting voltage vector of the five-phase winding has two values and can change discretely depending on the time sequence of the phase alternation. This property can be used to regulate the engine speed in a modern traction electric drive [4,5].…”

This paper shows a model of a five-phase synchronous motor with permanent magnets and a simulation model of a control device. A simulation model in the SimInTech software product is built. The transient time is 0.03 s when a stepped input is applied. When the load moment of inertia increases by a factor of 10, the accuracy of speed response decreases. The maximum motor speed error is 40% at a time of 0.2 s. This is a consequence of changing the model of the control object. It is suggested to perform model identification and adapt PI controllers according to load parameters.
