Abstract: A drive drum is disclosed for a belt conveyor that gearlessly drives a conveyed product. For example, at least one motor is located inside the drum shell, said motor being fixed to the drum shell by means of a motor frame on the shell and to a fixed drum shaft by means of a fixed motor frame on said shaft; the drum shell is sealed on both sides by a base on the end face, said bases being provided with centric bearings that support the fixed drum shaft; the two ends of the fixed drum shaft are mounted on shaft fixings; at least one electric connection line, which extends inside or along the drum shaft, runs between a winding of the motor that is fixed to the fixed motor frame, on the shaft and an electric energy supply; the motor(s) has or have a cooling device for the winding; and a coolant supply and a coolant drain of the cooling device and/or a coolant connection line extend inside or along the drum shaft.
