摘要： A stepper motor of the permanent-magnet sheet-metal type is constructed of a number of modules, simplifying assembly. The modular parts include a stator having integrally-molded winding bobbins and pole pieces. A rotor mounted in the stator includes a barrier member which separates a plastic, threaded hub molded interiorly from a permanent magnet molded exteriorly. A shaft having a first threaded end rotatably engaged with the interior of the rotor hub has a rectangular central portion extending through a rectangular opening of the stator to convert rotary motion of the rotor to linear motion of the shaft. An opposite end of the shaft includes a molded head and a tubular shield extending from the head. This shield and a tubular portion of the stator molding define a labyrinthal passage which inhibits the passage of contaminants into the rotor. A housing of the motor and a rotatably attached flange include engagable portions to lock the flange at a desired angular position.

摘要： The stepper motor comprises a multi-pole composite magnet which functions as a rotor, two stator members which determine the angular position of this rotor, and means for positioning the rotor and the stator members on a common axis. The composite magnet comprises two sections, each section having a plurality of projections and apertures. The projections and apertures on a first section mate with the apertures and projections, respectively, on the second section. The first and second sections are magnetized in opposite axial directions. Each stator member has a plurality of pole pieces which are positioned in operative relation to the composite magnet. In one embodiment, two windings are formed on each stator member. Applying current to one or both of these determines the polarity of the pole pieces on that stator member. In another embodiment, a stator member comprises a hollow, toroid-shaped trough. Pole fingers extend from the edges opposite the edges defining the bottom of the trough. Two windings are placed in the trough and the pole fringes are then bent to secure these windings and complete the electromagnetic circuit.

摘要： A rotating electrical machine includes a rotor and a stator including an annular stator core including core pieces connected to each other in a circumferential direction. Each of the core pieces includes a core back piece extending in the circumferential direction and a tooth radially extending from the core back piece. At least one of the coupling portions between the core back pieces adjacent in the circumferential direction is a first coupling portion. Each of the pair of core back pieces connected in the circumferential direction via the first coupling portion includes a first surface and a second surface continuously connected to the first surface in the radial direction. In the pair of core back pieces connected in the circumferential direction, the first surface of one core back piece and the first surface of the other core back piece are in contact with each other.

摘要： A rotor with four axially stacked rotor cores, and a plurality of field magnets interposed between them. Each rotor core includes a rotor-side claw-shaped magnetic pole. Each rotor-side claw-shaped magnetic poles are respectively extending from and formed on each rotor core at equal angle intervals. Tip end surfaces of the first and third rotor-side claw-shaped magnetic pole abut against or are closely opposed to each other axially. Tip end surfaces of the second and fourth rotor-side claw-shaped magnetic poles abut against or are closely opposed to each other in the axial direction. The plurality of field magnets are magnetized in the axial direction such that the field magnets causes the first and third rotor-side claw-shaped magnetic poles to function as first magnetic poles, and cause the second and fourth rotor-side claw-shaped magnetic poles to function as second magnetic poles.

摘要： The described technology relates to a stator of a planar type motor and a planar type motor using the same, which are easy to manufacture and are capable of reducing core losses, thereby maximizing motor performance. First cores that are difficult to form by stacking electrical steel plates are formed of soft magnetic powders, and second cores that are formed by stacking electrical steel plates having the same size are arranged in a region where a vortex is concentrated, thereby allowing easy manufacture and being capable of maximizing the performance of the planar type motor.
