Zusammenfassung: | A motor includes: a stator having an annular stator core and multiple teeth protruding radially inwards from the stator core; a coil wound around the teeth; a shaft rotating around the rotation axis radially inside of the stator core; a rotor core fixed to the shaft; magnets positioned on the outer peripheral surface of the rotor core; a salient pole positioned between magnets adjacent to each other in the circumferential direction; an applying portion applying a voltage to the coil; and an applying control portion controlling the applying portion. The ratio of the number of magnetic poles of the magnets and the number of teeth is 2:3. The voltage is a rectangular wave, and its application is started when the tip of the salient pole does not face an opening in the teeth. |
