Abstract:
1. An electric motor comprising a stator with a plurality of radially arranged pole shoes that project outwardly to define a plurality of outer surfaces and between which slots are formed, a rotor which rotates within the stator and has a rotor shaft which is mounted on both sides of the rotor, isolating stars for covering the end faces of the pole shoes, a stator winding which is situated in the slots and surrounds the end-face isolating stars, and an outer stator casing contacting the plurality of pole shoes of the stator at their outer surfaces, wherein the stator winding uses the isolating stars to secure the rotor and, at a respective end, encloses the rotor bearings and the rotor in its position in the stator, the stator has a tubular stator core having a central stator tube for accommodating the rotor, the isolating stars are spaced apart from one another by the stator core and do not contact each other, and one of the isolating stars is provided with a plurality of retaining pins for the stator winding and/or a printed circuit board.
