ABSTRACT:
An improved electronic timepiece transducer wherein the construction of the permanent magnet rotor and a magnetic permeable stator effects a reduction in energy consumption during operation. In particular, the rotor is characterized by a predetermined thickness and at least two concentric circular equal radii surfaces having the same radius. Similarly, the stator includes highly permeable stator poles having a predetermined thickness and two symmetrical equal radii semi-circular stator surfaces having the same radius and surrounding the rotor. The ratio of the rotor radii to the stator radii and the ratio of the rotor thickness to the stator thickness define a specific relationship that effects a reduction in the energy consumed by the step motor during operation.
