Winding machine with motor control for load lifting
A newly granted patent (Publication Number: US12012316B2) details a winding machine designed to lift and lower loads by winding up and down a load chain or rope. The machine includes a winder, drive motor, motor controller, load detector, and operation device. The motor controller can operate in a balancer mode, offering a first balancer mode that assists the operator's force and a second balancer mode that does not. The machine can control the direction of the operating force in a specified position range, ensuring efficient load management.
Furthermore, the patent outlines a method for controlling the winding machine's operation, involving load torque detection and torque control steps. The motor controller can switch between the first and second balancer modes based on the direction of the operating force, optimizing the lifting and lowering process. The method allows for precise control of the drive motor within predetermined position ranges, enhancing the machine's overall performance and safety during load handling operations.
