Abstract: Disclosed is a motor control apparatus capable of checking whether there is an abnormality in connections of a plurality of motors, and switching connection schemes between an inverter and the motors or driving the motor in an electronic apparatus including one inverter configured to control a driving operation of the plurality of motors. For example, the motor control apparatus includes an inverter configured to convert DC power into AC power and provide the AC power to one of a plurality of motors, a switch configured to switch connection schemes between the inverter and the plurality of motors, and a controller, and the controller may control the inverter to output an input signal of a predetermined pattern in response to the switching of the connection schemes by the switch, and generate a control signal for controlling the inverter or the switch on the basis of a response signal corresponding to the input signal. Other example embodiments may be provided.
