Abstract
(EN)
The present invention can provide a motor comprising: a rotary shaft; a yoke coupled to the rotary shaft; a stator disposed between the rotary shaft and the yoke; a first magnet and a second magnet disposed at the yoke; and a circuit board on which a first hall sensor disposed to correspond to the first magnet and a second hall sensor disposed to correspond to the second magnet are disposed, wherein the second magnet includes a plurality of split magnets and one index magnet, the circumferential width of the split magnet is the same as the circumferential width of the index magnet, the split magnet and the index magnet are respectively formed by combining a first pole and a second pole, the circumferential width of the first pole of the split magnet is the same as the circumferential width of the second pole thereof, and the circumferential width of the first pole of the index magnet is different from the circumferential width of the second pole thereof.
