Abstract
According to one embodiment, a motor driving device includes an output part that supplies an exciting current to an exciting coil, a position detection part that detects a rotational position of a rotor, and a driving control part that produces a driving signal that is based on a detection signal from the position detection part and supplies it to the output part. The position detection part has first, second, and third detection elements that are integrally integrated together with the driving control part and detect rotational positions of the rotor.
