PROCESS FOR MANUFACTURING STATORS FOR STEPPING MOTORS OF ELECTRONIC WATCHES, AND MOTOR REALIZED ACCORDING TO THE PROCESS |
摘要 |
<p>A stator for a stepping motor comprises a cylindrical coil of compact size formed by winding wire directly on the center portion of a core. This center portion is coated with a film formed of a hard, compact insulating material adhering strongly to the core. An electrophoresis operation is used to obtain a film of minimum thickness in an efficient manner. The core includes end lugs which are bare on one face so that metallic contact can be established with the pole pieces of the stator. Prior to electrophoresis, the faces of the lugs intended to be bare are covered with a mask of synthetic material, preferably deposited while dissolved in a suitable solvent.</p> |
