Utilizing non-overlap windings has emerged as a favourable choice for minimizing electrical machine manufacturing costs, among other benefits. Nevertheless, it is widely acknowledged that these windings exhibit a notable level of harmonic contents in

The use of non-overlap windings rather than overlap windings is a topic for debate. Non-overlap windings are generally cheaper and easier to manufacture, but result in a high amount of magnetomotive force sub- and higher-order harmonics. A strategy t

The focus of the paper is on the reduction of core losses of large wound-rotor synchronous machines with non-overlap stator windings. The wound-rotor synchronous machine, being one of the alternatives to the permanent magnet synchronous machine, has
