تأثیر ترمینال های سیمانی مخلوط بر راندمان گشتاور ماشین های القایی پنج فاز

In this paper, the authors take a particular look at the influence of mixed stator winding arrangements on torque ripple production in a 30 stator slots, 2-pole, and five-phase induction machine. The conventional five-phase double layer windings with 14/15 and 13/15 chorded coils are compared with the proposed five-phase mixed winding arrangements. This paper presents the design consideration and calculation of winding factors of the proposed mixed winding configurations. The different five-phase winding arrangements have been modelled using Finite Element Methods. The results obtained from simulation are compared to those obtained from experimental measurements. Both simulation and practical results have proven that the combination of double and triple layer winding, mixed with coil side shift to other layer, has tremendously reduced the torque ripple factor while maintaining the torque average.
