摘要： The invention relates to a step motor particularly for an electronic timepiece, comprising a stator whose two free ends constitute two pole pieces 4, 5, delimiting therebetween an air-gap 6 in which is accommodated the rotor 2. Each pole piece is provided with a recess 8 of cylindrical shape so that the axis of each cylinder is parallel with the axis of rotation Ar of the rotor 2. The two axes of the said cylinders are shifted from one another by a value comprised between 80.mu. and 200.mu. in a direction perpendicular to the plane P defined by the axis of rotation Ar of the rotor 2 and the main direction of the flux 13 generated by an exciting coil associated with the stator. The radii of the rotor 2 and the stator 3 are in the order of about 800.mu. and 1500.mu. respectively.

摘要： An electromagnetic stepping motor has a stator assembly comprising two pieces. These two pieces are assembled to each other by a protrusion of cylindrical shape of one of the pieces which engages in a recess, of corresponding shape, in an extension of the other piece. The two pieces, which are of elongated general shape, are disposed parallel to each other with said one piece constituting the core of an energizing coil of the motor. The coil can be wound directly on to the piece of the stator constituting the core of the coil.

摘要： A two part laminated stator in which a ring portion, bearing shading coils, has a pair of spaced parallel legs projecting therefrom, each leg end being adapted for a welded connection with a corepiece end, the corepiece being adapted to be inserted in an axially extending hole in a bobbin on which a coil has been wound. Each leg end and each polepiece end is shaped to have a complementary line of contact shaped for full line contact without interference as the corepiece, bearing the wound bobbin, and the leg ends are pressed together in opposite directions parallel to the line in which the legs project. The two parts and the laminations of each part are then secured together along a strip weld across the outer edge of the laminations at the outer end of the line of contact for each leg and each polepiece end.

摘要： A two-pole off-set construction of an electric motor has winding portion laminations and rotor portion laminations which are separate so that the winding may be formed or placed on the winding portion and then the two portions of the stator interconnected to complete the flux path for the rotor circumscribed by a rotor aperture in the rotor portion. There must be a window space between these two portions to accommodate the winding on the winding portion and formerly the metal removed from this window space was scrap metal, necessitating an excessive amount of steel lamination material. In this invention, the layer of lamination is made in two complementary pieces and this layer has a rotor portion and a winding portion. The two separate lamination pieces for a layer of complete lamination are to permit the winding to be placed on this complete stator. The material removed from the window space instead of being scrap is utilized as an active flux carrying member by being unitary with one of these first and second lamination pieces.
