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： Systems and methods for providing a current control loop for an actuator. A typical system includes a current command controller setting a command current, the current command controller being coupled to a drive circuit used to drive the actuator and a sampling module sampling a motor current of the actuator. The system also includes a summation module calculating a current error based on the motor current, the current error being calculated by subtracting the motor current from the command current. The current error is used to compensate for an error in the motor current of the actuator. The sampling module can include a switch and a capacitor coupled in parallel with the resistor when the switch is on, a charge on the capacitor being proportional to the voltage drop across the resistor. Methods for setting a maximum control current and for providing the current control loop are also illustrated.

摘要： An actuator including an electric motor driven by a drive circuit powered by a power source, and a load coupled to the electric motor. The actuator further includes a spring biasing the load to a first position, and a microcontroller coupled to the electric motor to commutate the electric motor. Upon failure of the power source, the spring returns the damper to the first position, and, as the spring returns the load to the first position, the electric motor is spun to generate electricity that is used to power the microcontroller. The microcontroller can govern a speed at which the spring returns the load to the first position. In addition, a potentiometer can be used to indicate when the load approaches the first position so that the microcontroller can slow the speed of return prior to the load reaching the first position.

摘要： The outer case of the display module 10 is constructed of static dissipative polypropylene components that house a circuit board 16 and display 14. When the display module 10 utilizes the hand held pendant option a front cover 18 is used. This front cover 18 provides a viewing window 20 to the display 14 and a flat surface to attach the membrane 22. When the display module 10 is to be mounted inside of an enclosure, the front cover is replaced by a flat plate 28 that then provides the viewing window 30 and flat surface membrane 32 requirements. The rear portion 12 of the display module 10 is used with either option and contains the necessary features to allow for either the front cover 18 or the flat plate 28 to be attached.

摘要： A damper unit for an air handling system. The damper unit includes a damper vane to regulate air flow, and a position indicator coupled to the vane. The damper also includes a sensing device that senses when the position indicator passes in close proximity thereto. A controller receives an index signal from the sensing device when the device detects the position indicator, and the controller resets a home position for the vane upon receipt of the index signal. The home position for the vane can be reset upon initialization of the damper and periodically thereafter, such as after each complete revolution of the vane.

摘要： A damper unit for an air circulation system. The damper unit includes an air flow opening, a damper vane for opening and closing the air flow opening, and a motor for moving the damper vane between the open and closed positions. The damper also includes at least two ports, each port being operable in an input and an output mode. When a control signal is received on one port, the signal is sent out on the other port, and vice versa. The ports can be identical in shape to receive the same shaped plug.
