Abstract:
A motor control apparatus includes: an excitation unit configured to excite a plurality of excitation phases of a motor; a measurement unit configured to measure a physical amount that changes according to an inductance of at least one of a plurality of coils that make up the plurality of excitation phases, when each of the plurality of excitation phases is excited; and a determination unit configured to determine a type of the motor based on measurement values of the physical amount measured by the measurement unit when each of the plurality of excitation phases is excited.
