Research and Evaluation of Electromagnetic Properties of Single-Layer Six-Phase Windings
In this chapter, the design of the electrical circuit diagrams for the single-layer symmetric concentrated (q = 1), preformed, concentric, and chain (q = 2 and q = 3) 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 clearly indicates a huge advantage of the single-layer six-phase windings against three-phase windings.
