Provided is a motor control device comprising a rotation angle detecting means for detecting the rotation angle of a motor and outputting a rotation angle signal, an abnormality sensing means for sensing the presence/absence of abnormalities in the rotation angle detecting means, a rotation angle estimating means for estimating the rotation angle of the motor and outputting an estimated rotation angle signal, and a drive control means for driving and controlling the motor, if the abnormality in the rotation angle detecting means is not sensed by the abnormality sensing means, on the basis of the rotation angle signal outputted from the rotation angle detecting means, and for driving and controlling the motor, if the abnormality in the rotation angle detecting means is sensed by the abnormality sensing means, on the basis of the estimated rotation angle signal outputted from the rotation angle estimating means. |
