    Abstract: A claw-pole type stepping motor comprises: a rotor assembly shaped substantially cylindrical, and having a center shaft; and a stator assembly composed of two cup-shaped stator units which are coupled to each other coaxially so as to axially sandwich the rotor assembly, and which each include a bobbin having a magnet wire wound therearound, and two pole tooth arrays magnetically connected to each other and shifted in phase from each other by an electrical angle of 180 degrees. In the motor, each stator unit further includes a cover ring which protects the magnet wire wound around the bobbin against resin injected when the stator unit is resin-molded for an integrated solid structure. The motor structured as described above can be successfully resin-molded so as to enable elimination of a motor case, thus achieving downsizing for the dimension of the eliminated motor case while maintaining a sufficient mechanical strength.

Additionally, there is a stator, loosely mounted around the shaft and positioned between the opposing permanent magnets, and having at least a first and second pole extending toward the first and second rotors respectively. Furthermore, there is a first and second wire coil wrapped around the first and second pole respectively to allow the formation of a first and second electromagnet respectively by passing electrical current through the first and second wire coil.

    Abstract: A stepping motor is equipped with a rotor, a supporting member that rotatably support the rotor, and stators that have multiple stator teeth and that face each other across the diameter of the rotor, wherein said multiple stator teeth are positioned such that they are apart from each other. Using the construction described above, it is possible to make the rotor diameter smaller than the conventional model, thereby reducing the overall size of the stepping motor. Therefore, it is possible to make the outer diameter of lens barrel smaller than the conventional model without changing the lens diameter, which in turn makes the overall size of the camera more compact.

    Abstract: An electric motor consisting of an inside stator part and a rotor part placed outside and concentrically in relation to the stator part, has a high number of permanent magnets (13) on the inside of the rotor part. The magnetic fields from these permanent magnets interact with magnetic fields between flux-conducting lamella blocks (30, 35) engaging the coil cores (8) on the stator. The lamella blocks (30, 35) are T- and .GAMMA.-shaped with top beams (25, 27) pointing in directions parallel to the axis, and the top beams (25, 27) are positioned to provide substantially circumferentially directed magnetic fields in flux gaps (36) therebetween. The magnetic fields in the flux gaps (36) between the top beams (25, 27) are reversed in successive order, and under time control from an electronic regulator.
