A magnetic detection unit outputs a detection signal which changes according to a change in a magnetic field. A magnetic pole direction calculation unit calculates a magnetic pole direction of a rotor based on the detection signal. A current detection unit detects a current flowing through each multiphase coil. A rotating magnetic field vector calculation unit calculates a vector of a rotating magnetic field based on magnitude of the detected current.
