    Abstract: A actuator in a HVAC system includes a motor and a drive device driven by the motor. The drive device is coupled to a movable HVAC component for driving the movable HVAC component between multiple positions. The actuator further includes a main actuator controller that determines when the drive device is approaching an end stop and a pulse width modulation (PWM) speed controller that generates a PWM speed output for controlling a speed of the motor. The PWM speed controller sets the PWM speed output to zero in response to a determination that the drive device is approaching the end stop. The PWM speed controller then increases the PWM speed output until the end stop is reached, thereby causing the speed of the motor to increase as the drive device approaches the end stop.

    Abstract: An actuator in a HVAC system includes a mechanical transducer, an input connection configured to receive a power supply line voltage, and a voltage divider circuit. The voltage divider circuit includes a first capacitor in series between the input connection and the mechanical transducer, a second capacitor in parallel with the first capacitor between the input connection and the mechanical transducer, and a first transistor operable to connect and disconnect the first capacitor and/or the second capacitor from the voltage divider circuit based on the power supply line voltage, thereby adjusting a capacitance between the input connection and the mechanical transducer. The voltage divider circuit is configured to receive the power supply line voltage from the input connection, use at least one of the first capacitor or the second capacitor to reduce the power supply line voltage to a reduced voltage, and provide the reduced voltage to the mechanical transducer.

    Abstract: An actuator in a HVAC system includes a housing, a mechanical transducer, and an input connection configured to receive a voltage signal having a power supply line voltage. The actuator includes a voltage divider circuit having a capacitor disposed in series between the input connection and the mechanical transducer. The capacitor has a capacitance value based on an electrical impedance of the mechanical transducer. The voltage divider circuit is configured to receive the line voltage from the input connection, to use the capacitor to reduce the line voltage to a reduced voltage, and to provide the reduced voltage to the mechanical transducer.

    Abstract: An actuator in a HVAC system includes an inductive sensor, a conductive target, and a controller. The conductive target has multiple different portions that become aligned with the inductive sensor as a position of the actuator changes. Each of the multiple different portions have a different inductance. The controller receives a signal from the inductive sensor indicating an observed inductance of the portion of the conductive target aligned with the inductive sensor. The controller uses a stored relationship between the observed inductance and the position of the actuator to determine the position of the actuator based on the observed inductance. The controller operates the actuator to change the position of the actuator based on the determined position.
