Method for manufacturing a timepiece stepping motor comprising the steps of: providing a flat one-piece stator member defining an opening for the rotor and having a pair of diametrically opposed narrow sections on either side of the opening; providing a movement frame having stator locating projections and defining a pair of holes larger than the narrow sections and extending through the movement frame; locating and attaching the stator to the frame with the narrow sections spanning the holes in the frame; cutting through the narrow sections with a laser to sever the stator into two members, utilizing the holes in the frame to dispose of vaporized metal from the stator; encapsulating and re-joining the severed sections with a plastic fixation; and attaching a coil core assembly to the stator members and in magnetic circuit therewith. |
