Abstract
An embodiment may provide a sensing device comprising: a stator comprising stator teeth; and a rotor comprising magnets, wherein: the stator teeth comprise a first stator tooth and a second stator tooth arranged to overlap the first stator tooth in the radial direction from the center of the stator; the first stator tooth comprises multiple first teeth and multiple third teeth, and the second stator tooth comprises multiple second teeth; one of the multiple first teeth is arranged to overlap one of the multiple second teeth in the radial direction; and the magnets are disposed between the multiple first teeth and the multiple third teeth, respectively.
Claims25
A sensing device comprising:
- a stator including stator teeth;
- and
- a rotor including a magnet,
- wherein the stator teeth include a first stator tooth and a second stator tooth disposed to overlap the first stator tooth in a radial direction from a center of the stator,
- the first stator tooth includes a plurality of first teeth and a plurality of third teeth,
- the second stator tooth includes a plurality of second teeth,
- one of the plurality of first teeth is arranged to overlap one of the plurality of second teeth in the radial direction, and
