Abstract
A motor control apparatus that vector-controls a sensorless motor includes an estimating unit configured to obtain an estimated phase value by estimating a phase of a rotor in the sensorless motor, and a generating unit configured to generate, from the estimated phase value and a phase command value of the rotor, a phase conversion value that is used for a coordinate conversion between a rotary coordinate system and a static coordinate system in the vector control. The generating unit is further configured to output the phase command value as the phase conversion value when the rotor is caused to start to rotate, and change the phase conversion value so that the phase conversion value approaches the estimated phase value from a predetermined timing after the rotor is caused to start to rotate.
