Abstract
For a simple adjustment, suitable for automation, of the axial play between the rotor (1, 2) and the stator (5 to 8) of a miniature electric motor, at least one bearing (3) is axially moved relative to its bearing sleeve (51) in the end bell (5) and is fixed in its adjustment position by deformation of the bearing sleeve in a form-locking manner. For axial fixation, especially when used for drives with large axial loads, a thrust shoulder (511, 512) is formed after the axial play is adjusted for the axial contact of the adjusted bearing (15) from the bearing sleeve (51) by hot molding, ultrasonic heat deformation. Alternatively, precut tabs may be formed on the sleeve by embossing to form a thrust shoulder.
