Abstract
A reel motor () for a driven conveyor roller has a stator () that is surrounded by a stator housing (). A rotor () drives a rotor shaft (). A tubular external housing () runs around the stator housing () at a distance in the circumferential direction. A cooling duct () is fluidically connected to an interior of the stator housing () holding the stator (). The cooling ductis formed between the external housing () and the stator housing (). An impeller wheel () is secured to the rotor shaft (). The impeller wheel generates a cooling air flow (K). The interior of the stator housing () and the cooling duct () determine a closed cooling circuit. The cooling air flow is guided through the closed cooling circuit.
