Motor driving control apparatus and motor driving control method

A motor driving control apparatus according to an embodiment includes a motor driving unit that selectively energizes the three-phase coils of a motor; a motor control unit that switches an energizing phase of the coils in a predetermined order, the energizing phase being a phase to which the motor driving unit energizes, 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 to the coils, and that short-circuits the coils in each of three pairs that are different combinations of two coils of the coils, in response to a short-circuiting signal; and a short-circuiting signal output unit that is connected between the interphase short-circuiting unit and the coil, and that outputs the short-circuiting signal to the interphase short-circuiting unit when an input of the brake control signal is received.
