Zusammenfassung:	To solve the problem that accuracy of determining a rotational phase of a rotator of a motor deteriorates due to variations in the magnitude of a current supplied to a winding.SOLUTION: On the basis of a value of a current supplied to a winding, a rotational phase is corrected. As a result, it is possible to prevent decrease in the accuracy of determining the rotational phase of a rotator of a motor due to variations in the magnitude of the current supplied to the winding. That is, control of the motor can be kept from becoming unstable.SELECTED DRAWING: Figure 5 【課題】巻線に供給される電流の大きさが変動することに起因してモータの回転子の回転位相を決定する精度が低下してしまう。【解決手段】巻線に供給される電流の値に基づいて、回転位相を補正する。この結果、巻線に供給される電流の大きさが変動することに起因してモータの回転子の回転位相を決定する精度が低下してしまうことを抑制することができる。即ち、モータの制御が不安定になってしまうことを抑制することができる。【選択図】図５
