Research and Evaluation of Electromagnetic Properties of Two-Layer Preformed Fractional-Slot Six-Phase Windings
In this chapter, the design of electrical circuit diagrams for the two-layer symmetric fractional-slot (q = 1/2, q = 3/2, and q = 5/2) six-phase windings is presented. For the designed windings, the investigation of their electromagnetic properties was accomplished using two methods discussed in the first chapter. The results of the research of electromagnetic parameters of the discussed windings were compared with the corresponding results of analogous three-phase windings, and this comparison indicates a clear advantage of the two-layer fractional-slot six-phase windings compared to three-phase windings.
