The cable drum 3 is rotatably supported by two ball bearings 11 on the circumference of the motor housing 2. The lower ring part 13 of the cable drum 3 protrudes beyond the Ieollerring 12 arranged below and overlaps it. The connection cable 4- for the motor 2 is rolled up on the outer circumference of the cable drum 3. One end of this cable is connected to two sole brushes H, from where the current is fed to the electric motor 2 via the two slip rings 15 and a connecting cable (not shown). The slip rings 15 are in turn on the Motorgehh>. s attached slip ring carrier 16 is arranged. The other end of the cable 4 is connected to the house installation.
