Abstract
The invention relates to an electric machine comprising a stator (1) and a rotor (2) movable relative to said stator. Said stator comprises two multi-stranded, concentrated windings (A1, B1, C1, A2, B2, C2) which are placed in respective slots of the stator (1). While the first winding (A1, B1, C1) comprises six coils, the second winding (A2, B2, C2) is designed to have twelve coils. The number of turns (Nw1) of the coils of the first winding is different from the number of turns (Nw2) of the coils of the second winding.
