Abstract
A motor driving control apparatus according to an embodiment includes: a motor driving unit that selectively energizes three-phase coils of a motor; a motor control unit that switches an energizing phase of the coils, the energizing phase being a phase to which the motor driving unit energizes, in a predetermined order by outputting a driving control signal to the motor driving unit; a brake control unit that outputs a brake control signal; an interphase short-circuiting unit that is connected between two-phase coils of the three-phase coils, and that short-circuits the two-phase coil in response to a short-circuiting signal; and a short-circuiting signal output unit that is connected between the interphase short-circuiting unit and one-phase coil that is not different from each of the two-phase coils of the three-phase coils, and that outputs a short-circuiting signal to the interphase short-circuiting unit when the brake control signal is received.
