ABSTRACT:
A synchronous motor for a timepiece capable of cancelling unbalance in self-starting driving power with regard to the oscillating direction at the time of self-starting, in which adjoining stator pole pitch angles are set at 0.5 times or 1.5 times the rotor pole pitch angle. Provision of specific directional performance is restricted to direction of self-starting rotation. The air gap between the stator supplementary poles and the rotor is set at a ratio between 1 and 1.4 against the air gap between the stator main poles and the rotor; width of the stator supplementary poles is wider than the stator main poles.
