ABSTRACT:
Asymmetrical shaded-pole motor (1) with a stator (2) consisting of a laminated core is formed from a C-shaped yoke, between whose free yoke prongs (7, 8), a yoke stay (4) is inserted, on which a main winding sits. A short-circuited auxiliary winding (9) is provided in the leg connecting the yoke prongs, and in a recess in this leg, there is a laminated squirrel-cage rotor (3) with a small air gap to the stator (2), mounted so it can rotate on a motor shaft (17). The squirrel-cage rotor (3) is designed as a hollow cylinder and directly surrounds coaxially a bearing supporting tube (13) that is connected to the stator (2) and projects into its interior from the open end, such that the motor shaft (17) is guided by bearings (14) in it, and is connected to the rotor (3) on the end opposite the bearing supporting tube (13).
