Abstract
A servoactuator () is operatively arranged to control the movement of an output member () in either of two directions in response to a command signal. The servoactuator includes an electric motor (); a motor controller (); a first transmission mechanism (); a hydrostatic second transmission mechanism (); a transfer mechanism () operatively arranged to selectively couple the motor output shaft to the output member either through the first transmission mechanism to impart a high-speed low-force drive to the output member, or through the second transmission mechanism to impart a low-speed high-force drive to the output member; at least one feed-back transducer (); and a servo control loop () closed about the motor, controller, transmission mechanisms, transfer mechanism, feedback transducer and output member for selectively controlling at least one of the position, velocity or force of the output member as a function of the command signal.
