PROBLEM TO BE SOLVED: To provide a brushless motor which enables a motor part to be controlled with higher accuracy and achieves further downsizing and weight reduction.SOLUTION: A first hall IC 94a and a second hall IC 94b, which face a first sensor magnet MG1 and are disposed along a rotation direction RO of a rotary shaft 46 at a predetermined interval, are provided on a first surface 91 of a control board 90 on which the rotary shaft 46 is located. A third hall IC 94c which faces the first sensor magnet MG1 and is disposed between the first hall IC 94a and the second hall IC 94b is provided on a second surface 92 of the control board 90 which is located at the opposite side of the first surface 91.SELECTED DRAWING: Figure 8

    【課題】モータ部をより高精度で制御可能としつつ、さらなる小型軽量化を図る。【解決手段】制御基板90の回転軸46がある側の第1面91に、第1センサマグネットMG1と対向するとともに、回転軸46の回転方向ROに沿って所定間隔で配置された第1ホールIC94aおよび第2ホールIC94bを設け、制御基板90の第1面91とは反対側の第2面92に、第1センサマグネットMG1と対向するとともに、第1ホールIC94aと第2ホールIC94bとの間に配置された第3ホールIC94cを設けた。【選択図】図8
