Abstract
A rotation detecting device includes a rotating direction determining means for determining a rotating direction of the rotor based on a first signal and a second signal, generating a rotating direction signal based on the first signal and the second signal, and outputting a rotating direction determining signal by switching the rotating direction signal with an external switching signal wherein the pulse signal generating means generates the pulse signal in response to the rotating direction determining signal.
