Two basic types of induction machines with combined star-delta stator windings have been analyzed by means of numerical simulations based on lump parameter and finite element method models. The use of suitably designed combined star-delta winding may lead ti the suppression of selected high spatial harmonics of the magnetic flux density in the air gap and, thus, to an improvement of the energy efficiency. the results of numerical simulations are verified by measurements on an experimental machine.
