Abstract:
A motor is a single-phase motor that includes a rotor having a plurality of magnetic poles and a stator provided to surround the rotor. The stator includes a yoke extending so as to surround a rotation axis of the rotor, a plurality of teeth extending in a direction from the yoke toward the rotation axis, the number of the plurality of teeth being equal to the number of the magnetic poles, and a sensor facing the rotor and disposed between two teeth adjacent to each other in a circumferential direction about the rotation axis among the plurality of teeth. A reference line is defined as a straight line passing through the rotation axis and a middle position between the two teeth in the circumferential direction. A center of the sensor in the circumferential direction is located at a position offset in the circumferential direction with respect to the reference line.
