A motor control device includes a motor drive circuit including an upper arm and a lower arm, an arithmetic processor to control the motor drive circuit, an alternative circuit that can operate as a substitute to replace the arithmetic processor, and a mode switch to switch a control mode between a first control mode, in which the arithmetic processor controls the motor drive circuit, and a second control mode, in which the alternative circuit controls the motor drive circuit, based on a state of the arithmetic processor. The mode switch switches the control mode from the first control mode to the second control mode when a state of the arithmetic processor changes from a normal state to an abnormal state.
