Embodiment Construction
[0022] The electric motor 1 is designed as an inner rotor motor and comprises a rotor 2 and a hollow cylindrical stator 3 which is arranged coaxially with respect to the rotor and surrounds the inner rotor 2 . The inner rotor 2 is not shown in the illustrated section. The exact configuration of the rotor is not shown in further detail. The rotor comprises permanent magnets or a plurality of permanent magnet segments distributed over the circumference. The housing of the electric motor according to the invention, in which all the parts of the electric motor are housed, is indicated by reference number 7 in the figures. The housing 7 consists of a very simple hollow cylindrical sleeve, preferably of steel. A case cover 8 is provided at either end of the case 7 in the axial direction, and the case cover 8 seals the case 7 in the axial direction. Both housing covers 8 contain a ball bearing 14 each for rotatably mounting the shaft 9 of the inner rotor 2 .
