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.

An internal rotor for an electric motor has a laminated rotor core with a multiplicity of rotor plates, and multiple pockets in each of which pocket a rotor magnet is at least partially arranged. The rotor plates have first recesses for forming the pockets and at least a first rotor plate which has at least a second recess associated with a first recess. A sprung web-shaped clamping element is formed between the second recess and the associated first recess, and tensioned toward the second recess by the associated rotor magnet to apply a force to the associated rotor magnet toward the first recess in order to hold the associated rotor magnet in the pocket. A rotor plate holds a rotor magnet in a pocket of a laminated rotor core.

An electric motor has an internal stator () and an external rotor (). The external rotor () has a rotor housing () and a plurality of magnets () mounted therein and is adapted to rotate around a rotation axis (); the magnets () are preferably bar magnets; the rotor housing () has an inner surface (), a first end (), and a second end () located opposite the first end () and the inner surface defines respective receiving surfaces () for reception of the magnets. each receiving surface features a channel depression () to receive a magnet (). The magnets () are each fastened on a respective one of the receiving surfaces () with the aid of an adhesive mounting agent (). A first bearing seat () for reception of a first bearing cage () is formed at the second end () of the rotor housing ().
