Functionality
Actuator for the operation of final control elements with preferably linear movement. The
actuator thrust rod transfers the force directly to the final control element.
A continuous power electronic unit controls the actuator. The electronic unit serves as the
interface between actuator and control system.
During continuous positioning the power electronic unit varies the motor torque steplessly until
the actuator force and the restoring process forces are balanced. High response sensitivity and
high positioning accuracy with short positioning time ensure an excellent control quality and a
long actuator life.
