    摘要： A motor in which drive current supplied to a winding is controlled in accordance with a rotational position of a rotor detected from a waveform of an induced voltage between phases. The motor is provided with a stator including 3×n teeth and windings for three phases. A rotor includes a rotor core, an n number of magnets, and an n number of salient poles. The magnets function as one of the magnetic poles, the salient poles function as the other one of the magnetic poles. Each salient pole is spaced apart by a gap from the adjacent ones of the magnets in the circumferential direction. The magnets and gap are arranged inward in the radial direction from the rotor core. An electrical angle between two ends of each magnet is set to be smaller than an electrical angle between two ends of each salient pole.

    摘要： A rotor comprises a rotor core, a plurality of magnetic poles arranged in a circumferential direction of the rotor core, a plurality of salient poles and a plurality of auxiliary magnets each of which is disposed between the magnetic pole and the salient pole is provided. Each magnet pole has a field magnet pole that serves as a first magnetic pole, wherein the field magnet is a main magnet. Each salient pole is integrally formed with the rotor core between the two adjacent magnetic poles. Each salient pole serves as a second magnetic pole. The pole of the second magnetic pole is opposite from that of the first magnetic pole. The auxiliary magnet generates magnetic flux in a circumferential direction of the rotor core so that the magnetic pole and an opposing pole of the auxiliary magnet have the same polarity and the salient pole and another opposing pole of the auxiliary magnet have the same polarity.
