Electronically commutated motor with bearing chamber defined by opposing abutment surfaces
Abstract:
An easy-to-assemble electric motor (21) features an internal stator (50), an external rotor (22) having a shaft (34), which external rotor is configured as a rotor cup or bell (24) having an outer side and an inner side (25), a bearing tube (70) for receiving a bearing arrangement (60) journaling the shaft (34), which bearing tube (70) has a first end portion (71) facing toward the inner side (25) of the external rotor (22) and being formed with an inwardly protruding stop (73), the bearing tube having a second end portion (75) facing away from the first end portion (71) and being joined to a plastic part (80) that likewise forms an inwardly protruding stop (77) adjacent a second end portion (75), the bearing arrangement (60) being located in the bearing tube (70) in a chamber defined between said two inwardly protruding stops (73, 77).
Abstract(Chinese):
