Abstract:
A motor control apparatus that is configured to perform a power distribution control on three-phase coils of a brushless motor and that is configured to perform a rotation control of a rotor includes: a plurality of switching elements that are arranged to be capable of switching a current which is allowed to flow through the coils; a plurality of sensors that are configured to detect a rotation position of the rotor; and a control part that is configured to output a drive signal for controlling a power distribution pattern of each switching element according to a position detection signal which is obtained by correcting a position detection signal as an output of the plurality of sensors by using a predetermined correction coefficient, wherein the control part is configured to add a correction angle that corresponds to a difference between the position detection signals before and after correction of a predetermined sensor among the plurality of sensors to a setting value of an advance angle of the power distribution control and select an output pattern that includes a plurality of power distribution patterns and that is used when selecting the power distribution pattern, from a plurality of different output patterns in accordance with the advance angle to which the correction angle is added and a power distribution angle of the power distribution control.
