Abstract: An annular stator provided with axial stator slots and stator teeth formed between adjacent stator slots. Each stator slot receives a conductor of a stator winding. The stator is formed of stator sectors. Each stator sector includes two outermost stator teeth and intermediate stator teeth between the two outermost stator teeth. A width of the two outermost stator teeth is equal. Adjacent stator slots within each stator sector are distanced by a first slot pitch and adjacent stator slots belonging to different stator sectors are distanced by a second slot pitch. The first slot pitch is smaller than the second slot pitch.
