BRUSHLESS MOTOR AND WIPER APPARATUS
摘要：
An object of the present invention is to provide a brushless motor and a wiper apparatus which allow high-precision control of a motor unit, and which can be reduced in size and weight. The first surface (91) of the control board (90) is provided on the same side as the rotating shaft (46) and the output shaft (51) so as to face the sensor magnet (MG1), the first and second Hall ICs (94a) and (94b) are mounted on the first surface (91). The second surface (92) of the control board (90) is provided on the opposite side from the first surface (91), and the third Hall IC (94c) is mounted on the second surface (92), and located between the first and second Hall ICs (94a) and (94b) so as to face the sensor magnet (MG1). In addition, the MR sensor (95) is mounted on the first surface (91) so as to face the second sensor magnet (MG2).
摘要（中）：

本发明的目的是提供一种能够高精度地控制电动机单元并且可以减小尺寸和重量的无刷电动机和擦拭装置。 控制板（90）的第一表面（91）设置在与旋转轴（46）相同的一侧并且输出轴（51）与传感器磁体（MG1）相对，第一和第二霍尔IC （94a）和（94b）安装在第一表面（91）上。 控制板（90）的第二表面（92）设置在与第一表面（91）相反的一侧，并且第三霍尔IC（94c）安装在第二表面（92）上，并且位于第一 和第二霍尔IC（94a）和（94b），以面对传感器磁体（MG1）。 此外，MR传感器（95）以与第二传感器磁体（MG2）相对的方式安装在第一表面（91）上。
