摘要：
An electric motor control apparatus includes a phase correction portion that generates and outputs an amount of phase correction with which to correct a phase of a signal from a position sensor detecting a position of a magnetic pole of an electric motor. The phase correction portion generates and outputs an energization stop signal in a case where a rotation speed of the electric motor is within a predetermined range and stores an amount of phase correction generated therein according to a comparison between a signal from the position sensor or a first phase and an induced voltage of the electric motor to output the amount of phase correction.
