モータ。 A rotor magnet having a plurality of magnetic poles is arranged on one surface of a single coil group having a three-phase configuration arranged on the stator board, and a rotor magnet having a plurality of magnetic poles is arranged on the other side of the single coil group integrally with the rotor magnet. In a brushless motor in which disks, which are rotating magnetic bodies, are opposed to each other, induction is induced by the three-phase single coil group on the other surface side of the magnetic circuit formed by the rotor magnet and the disk. A three-phase coreless brushless motor is provided with magnetostrictive means for including odd-order harmonics in the components of the back electromotive voltage waveform.
