Abstract

A motor control device includes an anomaly detection means that detects an anomaly occurring on power feeding paths of respective phases on the basis of first electric current values, second electric current values of the respective phases and a phase electric current value obtained by the first electric current values and the second electric current values. When at least one of an absolute value of the first electric current value and an absolute value of the second electric current value exceeds a first threshold value corresponding to a limit value of an electric current detection and an absolute value of the phase electric current value is smaller than a second threshold value corresponding to zero in any one phase, the anomaly detection means determines that an anomaly of an electric current sensor has occurred as regards the corresponding phase.
