Prediction of Losses and Efficiency for Three-Phase Induction Machines Equipped With Combined Star–Delta Windings


Combined star&#x2013;delta windings in electrical machines result in a higher fundamental winding factor and cause a smaller spatial harmonic content. This leads to lower <italic>I</italic><sup>2</sup><italic>R</italic> losses in the stator and the rotor windings, and thus to an increased efficiency. However, compared with an equivalent six-phase winding… (More)
