Tethered control for direct drive motor integrated into damper blade

A method for controlling air flow, comprising:

• disposing a damper on a duct;
• disposing an energy storage system within the duct a first predetermined distance from the damper;
• disposing a support on a blade of the damper, wherein the support includes a first flange configured to couple to a rotary motor and a second flange configured to couple to a surface of the blade, and wherein the first flange and the second flange are rigidly coupled to one another;
• disposing the rotary motor on the first flange of the support, wherein the rotary motor is configured to drive rotation of the blade about an axis, and wherein the surface of the blade extends in a direction along the axis;
• and controlling an operation of the damper using a controller coupled to the damper by a conductor and to the energy storage system, the controller disposed within the duct.

A system for controlling air flow comprising:

• a damper disposed on a duct;
• an energy recovery system disposed within the duct a first predetermined distance from the damper and a damper controller coupled to the damper and to the energy recovery system, the damper controller disposed within the duct a second predetermined distance from the damper, wherein the energy recovery system is coupled to the damper controller;
• an energy storage system coupled to the energy recovery system and configured to store energy for operation of the damper controller and the damper, wherein the damper further comprises:
• a rotary motor configured to drive rotation of a blade of the damper about an axis;
• and
• a support including a first flange configured to couple to the rotary motor and a second flange configured to couple to a surface of the blade, wherein the first flange and the second flange are rigidly coupled on one another, wherein the surface of the blade extends in a direction along the axis, and wherein the damper controller is disposed in the duct and is coupled to the duct by a magnetic clasp;
• and
• a main controller wirelessly coupled to the damper controller, wherein the main controller further comprises an indicator configured to generate a status indication for the damper controller, wherein the energy recovery system is configured to generate energy from the air flow to be stored by the energy storage system, and wherein the damper controller further comprises:
• a damper position sensor configured to read one or more position sensors on the damper to determine a degree to which the damper is open;
• a wireless controller interface configured to transmit data from the damper controller and to receive external data for the damper controller;
• and
• a voltage monitor system configured to monitor a voltage level of an energy storage device, wherein the damper controller is configured to:
• control an operation of the damper via the rotary motor, wherein the rotary motor is configured to open and close the damper;
• determine a charge state of the energy storage system;
• generate an alert if the charge state of the energy storage system is less than a first level;
• fully open the damper if the charge state of the energy storage system is less than a second level;
• and
• change a position of the damper if the charge state of the energy storage system increases from below the second level to above the second level.
