ABSTRACT:
An actuator for an HVAC system includes a motor coupled by an electrically operated clutch to a gear train which drives an output connector. A spring is connected to the transmission to drive the output connector to a normal position in the event of a power failure. A control apparatus is connected to the transmission and provides the combined functions of a magnetic eddy current brake and a motion sensor.
