ABSTRACT:
This invention develops an automated procedure which permits the settling of the axial play of a rotor using a stator sleeve pressed onto the rotor shaft and held in place during assembly by an insulating end disc which mates at an end face with the laminated rotor core, whereby assuring the smallest number of assembly steps. According to this invention, the insulating end disc is injection-moulded in one piece along with the spacer sleeve with an intermediate weak rated point in the form of either elastic or break-away intermediate segments which permit a relative setting motion between the insulating end disc which contacts the end face of the laminated rotor core, and the spacer sleeve pressed on the rotor shaft. This invention is particularly suitable for small commutator motors with rotor shafts mounted in sleeve bearings.
