Abstract:
A motor control apparatus, includes: a voltage control unit configured to control a voltage to apply to a plurality of coils in order to cause a rotor of a motor that includes the plurality of coils to rotate; a holding unit configured to hold information that indicates a magnitude of a load of the motor; and a detection unit configured to, based on the information that indicates the magnitude of the load that is held by the holding unit, set a detection condition for a stop position of the rotor, and perform detection processing of the stop position of the rotor in accordance with the set detection condition.
