Title: DRIVE UNIT FOR A DRUM MOTOR, DRUM MOTOR, REAR FLANGE AND PRODUCTION METHOD
Abstract:
The invention relates to an electrical drive unit (3) for a drum motor (1), to a drum motor, to a rear flange (10, 10') for an electrical drive unit, and also to a method for producing an electrical drive unit for producing a drum motor. The drive unit comprises an electrical drive apparatus having a stator (32) and a rotor (31) which are arranged in a stator housing (11) which extends along a longitudinal axis, a cable (900, 900'), wherein a first section of the cable is connected to the drive apparatus and a liquid encapsulation (930) is arranged on a second section of the cable which has individual lines which are litz wires, wherein a rear flange is arranged at one end of the stator housing, said rear flange having an annular space (140, 140') at an end side which is averted from the interior of the stator housing, wherein the liquid encapsulation is arranged in the annular space.
