ELECTRIC CYLINDER SYSTEM

摘要

An electric cylinder system includes: an electric cylinder; and a control section that controls the electric cylinder. The electric cylinder includes: an outer cylinder; a rod configured to be capable of extending and retracting in an axis direction from an opening on one end side of the outer cylinder; a bearing provided on the inside of the outer cylinder; a rotating shaft rotatably supported by the bearing and driven to rotate with driving force of a motor; a screw mechanism that converts a rotary motion of the rotating shaft into a linear motion of the rod and transmits the linear motion; and a load detecting section that detects a load in an axis direction applied to the rod in a position where the load is transmitted from the rod through the screw mechanism. The control section controls the electric cylinder on the basis of a signal from an encoder of the motor and a signal from the load detecting section.
