摘要： A primary disc and the secondary discs are each fitted with magnetic means, typically in the form of permanent magnets of the same polarity, located along a radial line from the centre point of the discs, and arranged generally transverse to the axis of rotation of the respective disc. As shown in the drawings, these magnets are also located at or adjacent to the periphery of the disc(s). The magnets are embedded into each of the primary and secondary discs such that the faces of the magnets are flush with the exterior faces of the primary and secondary discs. In the embodiment, each of the magnets embedded in the primary disc has a North pole which is aligned with a North pole of a magnet embedded in the secondary disc. Each of the South pole of those magnets embedded in the primary disc has a South pole which is aligned with a South pole of a magnet embedded in the other secondary disc. In some embodiments, the magnets on the primary and secondary discs are arranged so as to be parallel, with their respective elongate, straight side edges aligned. In use, such an arrangement can result in less slippage between the discs which hold the magnets, and can assist in handling some misalignment which may occur between these discs during use, thus allowing smoother operation.
摘要翻译：主盘和次盘各配有磁性装置，通常以相同极性的永久磁铁的形式，沿着从盘的中心点的径向线定位，并且大致横向于旋转轴线相应的盘。如图所示，这些磁体也位于或邻近盘的周边。磁体被嵌入到每个主盘和副盘中，使得磁体的表面与主盘和副盘的外表面齐平。在该实施例中，嵌入在主盘中的每个磁体具有与嵌入在次盘中的磁体的北极对准的北极。嵌入在主盘中的那些磁体的每个南极具有与固定在另一副盘中的磁体的南极对准的南极。在一些实施例中，主盘和副盘上的磁体被布置成平行，并且它们各自的细长的直边侧对准。在使用中，这种布置可以在保持磁体的盘之间导致更少的滑动，并且可以有助于处理在使用期间可能在这些盘之间发生的一些不对准，从而允许更平稳的操作。

摘要： In a motor, a rotor made of a permanent magnet which is equally divided in the circumferential direction to be alternately magnetized to different poles is formed into a cylindrical shape. The first coil, the rotor, and the second coil are sequentially arranged in the axial direction of the rotor. The first outer and inner magnetic poles excited by the first coil are set to oppose the outer and inner circumferential surfaces, respectively, of the rotor, and the second outer and inner magnetic poles excited by the second coil are set to oppose the outer and inner circumferential surfaces, respectively, of the rotor. An electric element is arranged at a position to oppose, across a predetermined gap, the circumferential surface of the permanent magnet not covered with the first or second outer magnetic pole. Alternatively, an electric element and a circuit pattern are formed on a connection member that connects the first and second outer magnetic poles to each other.

摘要： A stepping motor includes a stator and a rotor. The stator has pole teeth projecting from the inner surface at a constant pitch. The rotor has first through fourth rotor sections, and permanent magnets are embedded into the outer surface of each of the first through fourth rotor sections at a pitch equal to the pitch of the pole teeth. Two coils are provided in the stator so as to generate looped magnetic fluxes in the stator. A first offset corresponding to one half of the pitch of the permanent magnets is provided between each permanent magnet of the first rotor section and a correspond permanent magnet of the second rotor section, and a second offset equal to the first offset is provided between each permanent magnet of the third rotor section and a correspond permanent magnet of the fourth rotor section. Further, a third offset corresponding to a quarter of the pitch of the permanent magnets is provided between each permanent magnet of the second rotor section and a correspond permanent magnet of the third rotor section. When current is supplied to the coils, driving forces are generated at the permanent magnets of the first and second rotor sections as well as at the permanent magnets of the third and fourth rotor sections. The rotor is rotated by these driving forces.

摘要： Iron surfaces of stator poles, rotor periphery, or both stator poles and rotor periphery, of stepping motors are manufactured without teeth. The stepping effects of teeth are obtained by bonding, to the toothless surfaces, webs composed of fluted magnetic material having alternate thin and thick sections magnetized in the direction of the thickness of the material and carrying soft magnetic inserts in the flutes. The inserts form virtual teeth. The thick sections are magnetized in the direction opposite to the thin section and the flutes extend in the direction transverse to the direction of relative motion between rotor and stator.
