In a drum motor having a driving electric motor and a gear transmission (16, 17, 18) between the motor armature (14) and an internal toothing (22) in an end cover (2) connected to the shell (1), the gear transmission (16, 17, 18) is offset with respect to the shaft (6) on which the end cover (2) is journalled, and this shaft (6) has an axial bore (8) through which the necessary wires (9) for supplying power to the electric motor are introduced. This enables stocking of a plurality of drum motors of different lengths and motor outputs merely by changing the length of the shell (1) and the length of the shaft (7) opposite the gear transmission (16, 17, 18), it being unnecessary to change the structure around the wire lead-in mount. The wires (9) may be run from the internal mouth (24) of the bore (8) to the stator winding (25) of the motor through a pipe section (23). |
