Abstract: A motor includes: a rotor comprising: a rotary shaft; a magnetic body rotatable together with the rotary shaft; and first and second permanent magnets fixed on an outer circumference or an inner circumference of the magnetic body, and a stator comprising: an iron core arranged around the rotor; and a coil for exciting the iron core.

Abstract: The method is capable of forming stator coils in dead spaces, into which a nozzle of a wire coiling machine is inserted, and improving space factor of the coils. The method comprises the steps of: regular-winding a magnet wire in vacant longitudinal outer parts of slots alternately, without getting into spaces for inserting the nozzle of the wire coiling machine; regular-winding the magnet wire in the rest vacant longitudinal outer parts of the slots and the spaces for inserting the nozzle; regular-winding the magnet wire in vacant longitudinal inner parts of the slots alternately, without getting into spaces for inserting the nozzle; and regular-winding the magnet wire in the rest vacant longitudinal inner parts of the slots and the spaces for inserting the nozzle.

Abstract: The method is capable of equalizing time lengths of stopping a motor at load-holding stop positions of respective phases so as to average amounts of heat generation of phase coils. The method for drive-controlling electric machinery, in which a multiphase motor is used as a driving source of an assist mechanism, is performed by a control unit including a driving circuit for driving the multiphase motor. The method is characterized in that the control unit controls to stop a rotor at a load-holding stop position, at which rotation of the rotor is stopped in a state where a motor coil is energized and the rotor is in a load-holding state, and that the load-holding stop position is angularly shifted an electric angle of 180/n (n is number of phases and an integer two or more) degrees, in a prescribed rotational direction, with respect to a previous load-holding stop position of the rotor.

Abstract: The electric motor of the present invention is capable of improving efficiency of level-winding coil cables and increasing lamination factors of coils. The coil cable, which is wound on first bobbins as first coils, has connection parts. The connection parts are respectively extended from a winding-start point of the first coil wound on each of the first bobbins and a winding-termination point thereof, for parallel winding, through a groove section located on the inner side of a second coil wound on each of second bobbins so as not to interfere with the second coil.

Abstract: An inner rotor brushless motor is miniaturized, flattened and made lighter without reducing motor performance. A rotor and a stator are enclosed inside a sealed case (i.e., a sealed space) assembled by covering an attachment base with a cup-shaped bracket. A motor substrate on which a motor driving circuit is formed is provided in a gap formed in an axial direction between (i) the rotor and the stator and (ii) a base portion inside a bracket opening of the bracket.
