TLDR
In this paper, a reel motor for a driven conveyor roller with a stator and an impeller wheel is described, where the rotor is driven by a rotor shaft and the impeller is secured to the stator.Abstract:
The invention relates to a reel motor (1) for a driven conveyor roller having a stator (11) which is surrounded by a stator housing (10), and a rotor (12) which is driven by a rotor shaft (13), also having a tubular external housing (30) which runs around the state housing (10) at a distance in the circumferential direction, wherein a cooling duct (20), which has a flow connection to an interior, holding the stator (11), of the stator housing (10) is formed between the external housing (30) and the stator housing (10), and an impeller wheel (14) which is secured to the rotor shaft (13) and is designed to generate a cooling air flow (K), wherein the interior of the stator housing (10) and a cooling duct (20) determine a closed cooling circuit through which the cooling air flow is guided.read more
