ABSTRACT:
An electric motor having a stator with a plurality of radially arranged pole shoes between which slots are arranged, 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, in which the stator winding uses the isolating stars to secure the rotor and, at the respective end, encloses the rotor bearings and the rotor in its position in the stator. The isolating stars are formed such that they may firstly accommodate the bearings for the rotor shaft and furthermore also may accommodate bearings for attachment of supports for accommodating the electronic circuits for electronic commutation. An electric motor of this type is distinguished by the capability to operate for long periods continuously, accompanied by high rotational speeds and small dimensions.
