Motor, electric blower, electric vacuum cleaner, and hand dryer

A motor of single-phase comprising:

• a rotor having a plurality of magnetic poles, and a stator provided to surround the rotor,
• the stator comprising:
• a yoke extending so as to surround a rotation axis of the rotor;
• a plurality of teeth extending from the yoke in a direction toward the rotation axis, a number of the plurality of teeth being equal to a 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,
• wherein the two teeth have asymmetrical shapes in the circumferential direction;
• wherein when 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, and
• wherein 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.
