Semi-rotary actuator
The semi-rotary actuator is controlled by a reciprocal input of compressed air.
In the end positions the semi-rotary actuator can activate switches or valves via labels.
An external load is determined by a mass. The distance e
from the center of gravity of the mass to the rotation axis can be specified. An additional moment of inertia is calculated with J = m * e * e from the distance and the mass. If the rotation axis is horizontal to the earth surface, also an additional torque is taken into account, which results from the force of gravity, the rotation angle and the distance e
. The position of the mass refers to the angle of rotation 0.
