Title:
ROTATIONAL SPEED CONTROL SYSTEM USING CLUTCH AND POLE CHANGE MOTOR
Document Type and Number:
WIPO Patent Application WO/2023/153667
Kind Code:
A1
Abstract:
The present invention relates to a rotational speed control system using a clutch and a pole change motor, the system characterized by comprising: a device that has, embedded therein, a clutch operation pressure-regulating valve, and a clutch and a gear for controlling a driven body in the same rotational direction as and the opposite rotational direction to a driving body; a pole change device; a pole change propulsion motor capable of changing the rotational speed of a motor; and a control unit that controls a time point of clutch opening and engagement before and after a pole change, so as to minimize occurrence of mechanical stress caused by a rapid change in the rotational speed of the pole change propulsion motor. The rotational speed control system using a clutch and a pole change motor according to the present invention is related to all equipment requiring rotational speed control.
