Abstract:
An electric motor comprising a rotor, an electromagnetic brake means for braking the rotor, and a stator wherein said stator comprises at least one pole pair, in which at least one pole of said pole pair comprises a pole shoe which faces inward towards the rotor and is surrounded by a stator winding, and wherein said at least one role of the stator supports the electromagnetic brake means and wherein the electromagnetic brake means comprises a brake element composed of an electromagnetically conductive material which is urged against a braking force by an attraction force generated by the magnetic flux induced during operation of the motor, wherein said brake element is constructed in the shape of a rocker element and is pivotally supported to pivot about an axis in a radially continuous free space within the stator such that the brake element applies a braking force to the rotor at a position offset from said axis.
