    摘要： A brushless motor includes a first rotor core, a second rotor core, and a field magnet member. The first rotor core includes primary projecting pieces arranged along a circumferential direction at equal intervals. The second rotor core has the same shape as the first rotor core, and includes secondary projecting pieces arranged along the circumferential direction at equal intervals. The secondary projecting pieces are positioned between the primary projecting pieces that are adjacent to one another in the circumferential direction. The field magnet member is arranged between the first rotor core and the second rotor core. The field magnet member is magnetized along an axial direction to generate primary magnetic poles in the primary projecting pieces, and generate secondary magnetic poles in the secondary projecting pieces. A rotor includes the first rotor core, the second rotor core, and the field magnet member.

    摘要： A rotor of a motor includes first and second rotor cores, a field magnet, and a commutator magnet. The first and second rotor cores each include a core base and a plurality of claw poles. The claw poles of the first rotor core and the claw poles of the second rotor core are alternately arranged in a circumferential direction. The field magnet is located between the core bases. The field magnet is magnetized in an axial direction so that the claw poles of the first rotor core and the claw poles of the second rotor core function as different magnetic poles in the circumferential direction. The commutator magnet is located on an outer circumference of the field magnet around the claw poles. The commutator magnet is magnetized so that surfaces having the same polarity face each other between the claw poles and the commutator magnet.

    摘要： In a control apparatus, a magnetic flux information acquiring unit acquires magnetic flux information of magnetic poles of a rotating electric machine. A fundamental setting unit sets a fundamental command value for supplying a fundamental current to a winding of the rotating electric machine. A harmonic setting unit sets, based on the magnetic flux information acquired by the magnetic flux information acquiring unit, a harmonic command value for supplying a reduction current to the winding. The reduction current is a harmonic current for reducing variation in a radial electromagnetic force acting on a rotor of the rotating electric machine. An operating unit operates, based on the fundamental command value set by the fundamental setting unit and the harmonic command value set by the harmonic setting unit, an electric power converter to supply the winding with a drive current that is obtained by superimposing the reduction current on the fundamental current.

    摘要： A rotor includes first and second rotor cores, a field magnet, and an annular magnet. The first and second rotor cores each include a core base and core magnetic poles. The core magnetic poles are provided on an outer peripheral portion of the core base at equal intervals. The core bases are faced with each other. The core magnetic poles are alternately arranged in a peripheral direction. The annular magnet is a resin molding product including a magnetic pole magnet portion and an inter-pole magnet portion. The annular magnet has a non-contact portion not in contact with the first and second rotor cores. A gate mark portion in injection molding of the annular magnet is arranged in the non-contact portion.
