Claim 0:
1. A damper for an HVAC system, comprising:
a base for providing support to the damper and for securing and sealing the damper on an air duct;
a damper blade assembly configured to regulate a flow of air passing through the air duct;
a drive motor comprising a drive gear;
a crank gear and a crankshaft, wherein the crank gear and the crankshaft are connected to each other such that the crank gear and the crank shaft rotate together, the crank gear being operatively coupled to the drive gear of the drive motor;
a rod coupled to the damper blade at a first rod end and coupled to the crank gear at a second rod end, the rod and crank gear configured to rotate the damper blade upon rotation of the crank gear via the drive motor;
a feedback system that includes a crank gear magnet disposed on the crank shaft proximate to the crank gear, the feedback system configured to determine a current position of the damper blade, wherein the crank shaft comprises a recess formed in the crank shaft and the crank gear magnet is disposed in the recess; and
a microcontroller operably coupled to the damper actuator, the microcontroller configured to instruct the damper actuator to open or close the damper blade assembly based on a wireless control signal received by the microcontroller from a remote controller.
