Abstract

A motor control device includes: a state monitoring unit that detects a power supply abnormality in which a power is not normally supplied to at least one of a rotation sensor and a motor; an abnormality determination unit that detects an abnormality of the rotation sensor based on an output signal of the rotation sensor; and a decision unit that decides whether to confirm the abnormality of the rotation sensor based on a detection result of the state monitoring unit and a detection result of the abnormality determination unit. When the state monitoring unit detects the power supply abnormality, the decision unit does not decide the abnormality of the rotation sensor even when the abnormality determination unit detects the abnormality of the rotation sensor.
