A motor control device includes: a motor driver configured to supply electric power to a motor having windings of a plurality of phases, the motor driver including, for each phase of the plurality of phases, an upper drive element and a lower drive element which are connected in series; a motor terminal voltage detector configured to detect a motor terminal voltage value based on a voltage of a motor terminal for each phase of the motor; a drive element fault determinator configured to perform fault determination for the upper drive elements and the lower drive elements, based on a voltage value across each drive element, and output a result of the fault determination; and a short/open-circuit fault determinator configured to, when the result of the fault determination output by the drive element fault determinator indicates that there is a fault, determine whether the fault is a short-circuit fault or an open-circuit fault, for the upper drive elements and the lower drive elements, based on the motor terminal voltage value detected by the motor terminal voltage detector.
