Summary:To improve the degree of freedom in design and reduce the size.SOLUTION: A servo motor includes a drive unit with a rotor and a stator, an input shaft to which the driving force of the driving unit is transmitted and rotated integrally with the rotor, a reducer that slows down the rotation speed of the input shaft and outputs the speed, an output shaft in which the driving force transmitted to the input shaft is transmitted via the reducer, an input side encoder disk attached to the input shaft, an output side encoder disk attached to the output shaft, a circuit board on which a predetermined circuit pattern is formed, an input side sensor mounted on the circuit board while facing the input side encoder disk, and an output side sensor mounted on the circuit board while facing the output side encoder disk, and at least one of the input side sensor and the output side sensor is mounted on the circuit board via a spacer board connected to the circuit board, and electronic components different from the input side sensor and the output side sensor are mounted on the circuit board.SELECTED DRAWING: Figure 3 【課題】 設計の自由度の向上及び小型化を図る。【解決手段】 ローターとステーターを有する駆動部と、駆動部の駆動力が伝達されローターと一体になって回転される入力軸と、入力軸の回転速度を減速して出力する減速機と、入力軸に伝達された駆動力が減速機を介して伝達される出力軸と、入力軸に取り付けられた入力側エンコーダーディスクと、出力軸に取り付けられた出力側エンコーダーディスクと、所定の回路パターンが形成された回路基板と、入力側エンコーダーディスクに対向した状態で回路基板に実装された入力側センサーと、出力側エンコーダーディスクに対向した状態で回路基板に実装された出力側センサーとを備え、入力側センサー又は出力側センサーの少なくとも一方が回路基板に接続されたスペーサー基板を介して回路基板に実装され、回路基板に入力側センサー及び出力側センサーとは異なる電子部品が実装された。【選択図】図３
