Sensing device

Abstract

An embodiment may provide a sensing device comprising: a rotor; a stator arranged so as to correspond to the rotor; a first collector arranged above the stator and a second collector arranged under the stator; and a first sensor and a second sensor arranged between the first collector and the second collector, wherein the first collector includes a first unit collector and a second unit collector, and a sensing value of at least one of the first sensor by magnetic flux and the second sensor by magnetic flux is compensated for on the basis of an offset obtained by multiplying, by a compensation coefficient, a difference value between a sensing value of the first sensor transmitted to the first unit collector and a sensing value of the second sensor transmitted to the second unit collector, the sensing value of the at least one of the first sensor and the second sensor being compensated for by selecting any one of a first offset and a second offset on the basis of a first difference value between the first offset that is an n−1st offset and the second offset that is an nth offset, and n being a positive integer.
