A motor control apparatus includes an inverter, a driver, a negative voltage circuit, a voltage dividing circuit, and a detection unit. The inverter includes an upper-arm switching element and a lower-arm switching element to supply a voltage of a node between the upper-arm switching element and the lower-arm switching element to a motor as a phase voltage. The driver applies a first voltage or a second voltage to the upper-arm switching element to control and turn the upper-arm switching element on and off. The negative voltage circuit supplies a voltage lower than the voltage of the node to the driver as the second voltage. The voltage dividing circuit performs voltage division between the negative voltage circuit and a negative power supply. The detection unit outputs a signal based on a voltage resulting from the voltage division by the voltage dividing circuit.
