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： This motor includes a stator whereupon a plurality of magnetic poles are arranged at first prescribed intervals on the outer circumference section, and a rotor which is rotatively arranged on the outer circumference of the stator by having a prescribed space in between and has permanent magnets magnetized to different polarities at second prescribed intervals.

摘要： The motor comprises a stator, a rotor, and magnets. The stator has a plurality of magnetic poles circumferentially arranged at first spaced intervals. The rotor is rotatably arranged in a position opposing to the stator. The magnets are arranged at second spaced intervals circumferentially on a surface of the rotor. The stator is formed by laminating plate materials, and a plurality of laminated plate materials at least including outermost layers of a laminated body thereof are bent in a direction substantially parallel to the magnet in order to form extended portions. And, when a magnet opposed area of pole tip portion being closest to a magnet including the extended portion is S, and a sectional area of magnetic pole is A, then area ratio (S/A) fulfills the relation of 4.8>(S/A).
