Abstract:
1. A damper actuator assembly including a processor and connected to a damper, the damper actuator assembly comprising: a) a gear train including a follower gear, the follower gear rotating less than a complete revolution for an entire range of travel of the damper; b) a sensor, wherein the sensor is a potentiometer, configured to monitor the position of the follower gear and configured to provide an electrical signal indicative of the angular position of the follower gear to the processor; c) the processor is configured to determine an angular speed corresponding to an angular speed of the follower gear based on the electric signal provided by the sensor at different times and configured to control a driving member at two or more non-zero speeds; d) wherein the processor is configured to control the driving member connected to the gear train and configured to drive the gear train at two or more different non-zero speeds depending on the electrical signal indicative of the angular position of the follower gear; and e) wherein the driving member controls the rotational speed of the follower gear such that the follower gear rotates to an open and closed position within a predetermined time.
