摘要： Disclosed herein are a motor driving apparatus and method. The motor driving apparatus includes: an inverter including a main driver sequentially activating N phases and a spare driver activating a spare phase substituting for a faulted phase among the activated N phases; a detecting unit detecting the respective output signals of the N phases; a switching unit performing switching so that the spare phase is connected to the faulted phase of the exited N phases; and a controlling unit driving the inverter to determine whether or not a fault is generated and control the switching unit so that the faulted phase is connected to the spare phase. Therefore, since the motor may be driven without replacing the inverter, a cost may be reduced, and since the motor may be driven without a change in the number of phases, the motor may be efficiently and stably driven.
