Abstract
A motor driving control apparatus in embodiments includes: a first signal generator to generate a first signal representing any one rotation angle section of plural rotation angle sections according to a sensor signal that changes every predetermined rotation angle of a rotor; a measurement unit to measure a period of each of the rotation angle sections; a prediction unit to predict a period of a next rotation section based on one or plural measured rotation angle sections; a second signal generator to generate a second signal representing a relative rotation angle of the rotor in the next rotation angle section for each period obtained by dividing the predicted period by a predetermined number; and a third signal generator to generate a third signal corresponding to a rotation angle of the rotor based on the first and second signals.
