Abstract
A motor driving control apparatus according to an embodiment includes an interphase short-circuiting unit that is connected to at least two-phase coils of the three-phase coils, and that short-circuits at least a pair of coils among three pairs that are different combinations of two coils of the three-phase coils, in response to a short-circuiting signal; a short-circuiting signal output unit that is connected between the coil and the interphase short-circuiting unit, and that outputs a short-circuiting signal to the interphase short-circuiting unit when an input of the brake control signal is received; and a protecting operation unit that stops the interphase short-circuiting unit short-circuiting the coils, based on a voltage condition of a one-phase coil of the three-phase coils.
