Abstract
A motor controlling device is provided that controls a brushless motor having a plurality of phases based on magnetic pole signals output by a plurality of magnetic pole signal output sections each corresponding to one of the phases. The motor controlling device includes an abnormality determining section, a signal generating section, and a motor controlling section. The abnormality determining section determines whether a magnetic pole signal output by each magnetic pole signal output section is an abnormal magnetic pole signal. When the abnormality determining section determines that at least one of the magnetic pole signals is an abnormal magnetic pole signal, the signal generating section generates a simulated signal corresponding to the abnormal magnetic pole signal based on the normal magnetic pole signals other than the abnormal magnetic pole signal and the rotational state of the brushless motor. The motor controlling section controls the brushless motor based on the simulated signal and the normal magnetic pole signals when the signal generating section generates the simulated signal.
