HEINZMANN Actuator StG 180-01 for basic SystemE 180 tested new

Large Diesel engines as well as gas engines or –turbine are the preferential application for this type of powerful actuators.

Two DC disc motors working on the same outputs shaft are their core they already generate strong torque in both directions and rotations. Additionally their torque is multiplied by a reduction gearbox.

Due to the low moment of inertia of the motor discs nevertheless quick response times can be gained. In case of voltages loss are turn springs ensures setting back to zero position. . A contactless feedback system is integrated onto the governor’s output shaft offering an electrical position signal to any external control unit.

A current limitation which is activated 20 seconds after the actuators might be blocked mechanically prevents them from damage by overheating.The use of special materials and long-time lubricants assures maintenance –free operation and long working life of the actuator.

All considered these actuator provides high regulation power even with only low current consumption and is quite indifferent to slow voltage changes of the supply.
