Document Type and Number:
WIPO Patent Application WO/2023/286510
Kind Code:
A1
Abstract:
[Problem] To provide a positioning device that enables highly accurate positioning control. [Solution] This positioning device comprises: an actuator formed using a direct-current motor 200 and a single-phase rotation sensor 20 that detects a speed reduction mechanism and a rotational displacement amount of the speed reduction mechanism; and an electronic control device 1 that electrically drives the direct-current motor. The electronic control device 1 performs speed reduction control so as to stop the direct-current motor 200 by using, as a target rotation stop position MP, a substantially intermediate position between a rising edge N+4f and a falling edge N+4r of an output pulse of the rotation sensor.
