  • Patent number: 4342930
    Abstract: The present invention concerns a miniature stepping motor 10 for a watch movement comprising a rotor 12 and a stator 11 pierced with a circular opening in which the rotor is located. A reinforcing band 18 surrounds the rotor concentrically and is pressed into the circular opening of the stator. This band 18 consists of a hollow cylindrical part 19 and an annular part 20 which closes at least partially the tubular piece constituting the band 18. A central opening in the annular part 20 provides a housing for the bearing 16 of the rotor axle.This band ensures a double function: that of making the stator rigid and that of centering the rotor.
