Abstract
A sensing apparatus includes a first sensor unit including a first hall sensor and a second hall sensor, wherein the first hall sensor outputs two first output values having different phases from each other, and the second hall sensor outputs two second output values having different phases from each other; a second sensor unit outputs a third position detection value of a rotor; and a control unit that compares a first position detection value of the rotor, which is on the basis of the first output values, with a second position detection value of the rotor, which is on the basis of the second output values, and compares at least one of the first position detection value of the rotor and the second position detection value of the rotor, with the third position detection value of the rotor outputted from the second sensor unit.
