3.1
Drive motor
A synchronous motor enables accurate speed control. The magnetic clutch serves as a
torque supervision to protect both actuator and damper.

Angular range and mechanical limitation
The illustration below shows the relationship between the inner and outer mechanical
limitation of the angular range.
