PROBLEM TO BE SOLVED: To provide a compact brushless motor.SOLUTION: A reaction-force motor 100 comprises: a shaft 50 supported by a housing 40 so as to freely rotate; a rotation angle sensor 90 that detects a rotation angle of the shaft 50; and a control board 80 where controllers 35, 36 that control rotation of a rotor 60 on the basis of the result of detection by the rotation angle sensor 90 are mounted. The control board 80 is accommodated in a housing 40, with the shaft 50 passing through the control board. The rotation angle sensor 90 is formed on the control board 80 and has: an excitation coil pattern 91a, in which an excitation signal is input and a detection coil pattern 91b, which outputs a detection signal; and a sensor rotor 92 fixed to the shaft 50 and rotated facing the excitation coil pattern 91a and the detection coil pattern 91b.SELECTED DRAWING: Figure 2

    【課題】コンパクトなブラシレスモータを提供すること。【解決手段】反力モータ100は、ハウジング40に回転自在に支持されたシャフト50と、シャフト50の回転角度を検出する回転角度センサ90と、回転角度センサ90の検出結果に基づいてロータ60の回転を制御するコントローラ35,36が実装された制御基板80と、を備え、制御基板80は、シャフト50が貫通してハウジング40に収容され、回転角度センサ90は、制御基板80に形成され、励磁信号が入力される励磁コイルパターン91a及び検出信号を出力する検出コイルパターン91bと、シャフト50に固定され、励磁コイルパターン91a及び検出コイルパターン91bに対向して回転するセンサロータ92と、を有する。【選択図】図2
