A drain pump for washing machines or dishwashers, which are driven electrically by means of a single-phase motor mounted on the pump housing (1), has a two-limbed stator, consisting of a laminate stack (12), between whose two limbs a rotor (8) is supported such that it can rotate and which carries an exciter winding (16), enclosed by a dielectric material jacket (15). In order to be able to assemble all the individual parts of this pump together in a few manufacturing processes, such that it is ready for connection, and in doing so always to ensure a constant separation between the two bearing holders (17 / 19) of the rotor shaft (7), there originate from the dielectric material jacket (15) of the exciter winding (16), in the same material, a first bearing holder (17) for the rotor shaft (7) and, on the opposite stator side, a centring ring (18) for the retention of a second bearing holder (19), which are connected to one another, in the same material, by means of webs passing through the laminate stack (12) of the stator, one of the two bearing holders (17 / 19) of the rotor shaft (7) being integrally formed on the pump housing (1) or on parts (4) thereof. <IMAGE> |
