Abstract:
This position detection system (1) includes a primary encoder (15) that detects the position of a motor shaft (13) of a motor (10), a secondary encoder (25) that detects the position of an output shaft (23) of a reducer (20), and an additional reducer (30, 30') that is disposed between the output shaft (23) and the secondary encoder (25). The reduction ratio of the additional reducer is set such that a rotating disc (25A) for the secondary encoder is within a single rotation of the entirety of the movable range of a machine provided with the motor and the reducer.
