A brake module () of a wheel module () has an anchor plate () adjacent to a wheel () and is indefinitely rotatable about the steering axis (L) with the wheel (). A lifting unit () is fixed adjacent to the anchor plate () and fixed about the steering axis (L). A brake wheel () is arranged on the wheel shaft () and is rotatable about the wheel axis (R) with the wheel (). At least one transfer element (') extends from the anchor plate () towards the brake wheel (). The lifting unit () is configured to move the anchor plate () from a first state to a second state. In the first state, the elements (′) are spaced apart without any contact. In the second state, the at least one transfer element (′) abuts against the brake wheel () generating a brake force at the brake wheel ().

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.
