摘要： A method and system are disclosed for adjusting the torque of a motor for a HVAC actuator based upon one or more operating conditions of the HVAC actuator. One illustrative HVAC actuator includes an actuated part, a motor for providing a torque to move the actuated part, a detector for detecting an operating condition in or around the HVAC actuator, and a controller for adjusting the torque in accordance with the detected operating condition.

摘要： A damper unit for an air circulation system. The damper unit includes a frame defining an air flow opening, a damper vane for opening and closing the air flow opening, and a stepper motor for turning the damper vane between the open and closed positions. The stepper motor is directly coupled to the damper vane to move the vane between the open and closed positions. A shaft of the stepper motor extends through a frame of the damper unit and is coupled to the damper vane by a hub. A controller is coupled to the stepper motor to control the stepper motor.

摘要： An actuator is provided having an electric motor that generates a back emf. The actuator also includes a control system for controlling the speed of the electric motor. The control system includes a controller and circuitry for allowing the controller to sample the back emf of the motor. The controller uses the sampled back emf as feedback representative of motor speed for use in controlling the speed of the motor.

摘要： An improved window operator has an electrically controlled drive for moving a window between opened and closed positions in response to a command. A plurality of switches are provided for manually or remotely commanding movement of the drive to move the window to a select desired position between the opened and closed positions. A position sensing routine senses actual position of the window between the open and closed positions. The position sensing routine includes a timer for storing a value representing actual position. The value is selectively incremented or decremented at a select rate in response to duration of operation of the drive to move the window between the open and closed positions. The control senses electrical power supplied to the drive. An adjustment routine adjusts the select rate of the timer in response to electric power deviating from a select desired power level. The control compare the desired position to actual position and controls an output coupled to the drive for developing an electrical signal to control the drive in response to a difference between the select and actual positions to minimize the difference.
