  • Patent number: 4270066
    Abstract: In an electronic timepiece motor, a one-piece stator of magnetic material having a hole therethrough bounded by a circumferential sidewall and defining a pair of stator portions connected by narrow bridges having small cross sections. The narrow bridges define a magnetic circuit of high magnetic resistance between the stator portions. A non-magnetic reinforcing ring is disposed within the hole through the one-piece stator and has an outer diameter effective to insure a snug fit of the reinforcing ring with the circumferential sidewall defining the hole through the stator. The reinforcing ring imparts stiffness to the one-piece stator to prevent deformation of the bridges and the hole. The reinforcing ring has a peripheral reinforcing flange extending outwardly and with the flange bearing against the one-piece stator adjacent the hole therethrough for imparting additional stiffness to the one-piece stator.
