The actuator, from Kyntronics, provides ‘power-on-demand,’ servo-controlled, variable-speed actuation.
The system combines the key benefits of an electronic servo system with the power density of hydraulics, and constitutes a standard, all-in-one (variable-speed motor, drive, cylinder) actuation system that precisely controls position, force and speed in applications requiring from 500 lbs (2,225 N) to more than 100,000 lbs (445 kN) of force capacity. With high force and quick cycle times in a compact package, the all-inclusive system produces strokes up to 120 inches (3,048 mm). The flexible system can be oriented in any position and features a compact footprint, combining the power-to-weight ratio advantage of hydraulic technology with the versatility, ease of installation and control of electric servo technology. It is powered by a servo motor driving a hydraulic pump that generates pressure to act on a cylinder to provide optimal mechanical actuation force. The configuration also features a servo drive controller, actuator, manifold and built-in transducers—providing essential closed-loop precision force and position control. Fieldbus capabilities include Ethernet, CAN and serial. The variable-speed servo motor eliminates the need for a proportional directional valve because the motor controls flow rate and direction. The unit is smaller than alternatives, and features energy efficiencies of 60-80 percent.
