Abstract
The invention relates to an electric machine comprising a stator and a rotor moveable relative to the stator. The stator has slots for accommodating electrical windings, wherein teeth of the stator are formed between adjacent slots. During operation of the machine, an operating wave of the magnetomotive force is different from a fundamental wave of the magnetic flux. The stator comprises at least one recess which is arranged in the tooth region and extends substantially in the radial direction.
