摘要： In a stator core having “N” slots, a tooth-width centerline of a linear yoke and a first extension line extended horizontally from a center of rotary shaft toward the linear yoke form a first angle. Assume there are first point on the first extension line at a first distance from the center, a second extension line drawn at a second distance horizontally from the center toward the linear yoke and extended vertically toward arc-shaped yokes, and a third extension line drawn from the center toward teeth ends of the linear yokes with angle “K”. The second and third extension line intersect at a second point. A line between the first and second points intersects with the first extension line, thereby forming the first angle. In this structure, 0

Then a sectional view of the rotor iron-core shows an arc drawn between the end points X and A, and the arc's center is the rotary center. The end points A and Z are connected by one or more than one straight lines in series.

摘要： A motor comprising a stator having a plurality of magnetic poles disposed in a circumferential direction along an outer periphery thereof, a rotor disposed rotatably around the outer periphery of the stator, and a magnet disposed in a circumferential direction along an inner periphery of the rotor. The stator is formed by laminating sheet-like plates. A plurality of the sheet-like plates including an outermost layer of this laminated body comprises a flat portion substantially perpendicular to the magnet, and an extended portion bent to a direction substantially parallel to the magnet. A part of the sheet-like plate having the extended portion disposed to the outermost side is formed into a thickness smaller than thicknesses of the other parts.

摘要： A rotor (21) is an interior permanent magnet rotor formed of a rotor core (24) in which a plurality of permanent magnets (25) are embedded at predetermined intervals. First protruding portions (26) and second protruding portions (27) are formed on an outer peripheral face of the rotor, the first protruding portions (26) each opposing the vicinity of a central portion of each of the permanent magnets and having a substantially arc-shaped cross section protruding outward and the second protruding portions (27) each opposing the vicinity of an end portion of each of the permanent magnets and protruding outward. One first protruding portion and two second protruding portions correspond to one permanent magnet. The formation of the first and second protruding portions as described above on the outer peripheral face of the rotor makes it possible to sufficiently reduce the torque ripple and the noise caused by the distortion of air-gap magnetic flux distribution.

摘要： A motor stator of the invention is provided with a laminated stator core comprising a plurality of core pieces having teeth and linked by intermediate thin-wall portions. The thin-wall portions are bent to form the stator core into an annular shape with two ends of the stator core joined by welding, and slots are formed between adjoining pairs of the teeth. A welded portion of the stator core is not near a center line in a radial direction of any of the slots.
