A motor control method includes acquiring n-phase currents, where n is an integer of three or more, of a first inverter, a GND current of the first inverter, n-phase currents of a second inverter, and a GND current of the second inverter, generating a first fault signal indicating presence or absence of a shunt resistor fault in the first inverter based on the n-phase currents and GND current of the first inverter and generating a second fault signal indicating presence or absence of a shunt resistor fault in the second inverter based on the n-phase currents and GND current of the second inverter, referring to a table representing a relationship between a set of levels of the first fault signal and the second fault signal and control modes and selecting one of the control modes, and controlling a motor in accordance with the selected control mode.
