Abstract
A rotor position detecting apparatus includes a rotor, a stator disposed in correspondence with the rotor and a sensing assembly disposed at one side of the rotor. The sensing assembly includes a substrate, a first magnetic element part and a second magnetic element part disposed on the substrate and a first ground pattern and a second ground pattern disposed on the substrate. The first ground pattern is electrically connected to the first magnetic element part. The second ground pattern is electrically connected to the second magnetic element part, and the first ground pattern is electrically disconnected from the second ground pattern.
