Abstract
An electromotive machine () comprises a rotor () and a stator (). The stator () comprises a first group of primary windings (), which are concentrated windings, arranged on a first side of the rotor () and a second group of primary windings () that are concentrated windings arranged on a second, opposite, side of the rotor (). The primary windings of each group comprise a plurality of coils that, in use, are supplied with current and produce a magnetic field. The windings of the second group () are displaced, relative to the windings of the first group () in order to cancel out an n-pole component of the magnetic field.
