4.12 Technical and mechanical design
4.12.1 Transmission of power
Incoming positioning signals are translated to positioning commands for the motor.
Function
principle
A
gear train transmits the motor’s positioning steps to the output stage (valve
coupling). Attached to the gear train are the electrical and mechanical accessory
items and the manual adjuster.
In the case of the rotary actuators, the adjustment to the required torque is made in
the output stage. With the stroke actuators, the translation from rotary to stroke
movement takes place in the output stage.
