1. A sensing device, comprising:
a rotor; and
a stator in which the rotor is disposed, wherein the stator includes stator teeth and a stator body, the stator teeth include first stator teeth and second stator teeth disposed inside of the first stator teeth, wherein at least one of the first stator teeth or the second stator teeth includes tips protruding toward a center of the stator, and wherein:
the first stator teeth include a first band, and a plurality of first teeth and third teeth extending from the first band;
the second stator teeth include a plurality of second teeth, and a plurality of second tips which are connected to the plurality of second teeth and protrude toward the center of the stator;
the stator body includes a first region and a second region disposed to be spaced apart from each other in a radial direction;
the first teeth and the third teeth are alternately disposed in a circumferential direction;
the third teeth are disposed outside of the first teeth in the radial direction;
the first region is disposed outside of the third teeth in the radial direction;
the second tips are disposed on one surface of the stator body; and
the first band and the second band overlap in the radial direction.
