Abstract

The invention relates to an electrical machine comprising a rotor and a stator, said rotor comprising permanent magnets and the stator comprising a coil and a stator pole which comprises stator surfaces which face the permanent magnets of the rotor, characterized in that at least one stator surface comprises a groove which is transverse to the movement direction of the rotor.
