  • Speed adjustment of an actuator for an HVAC system
    Patent number: 10203671
    Abstract: An actuator in an HVAC system includes a housing, a motor, a hub configured to receive a shaft, and a processing circuit. The processing circuit is configured to operate the actuator in at least a first speed mode and a second speed mode that is faster than the first speed mode. The processing circuit is further configured to perform a calibration process for the actuator. The calibration process includes temporarily shifting the actuator from the first speed mode to the second speed mode and driving the shaft through a predetermined sequence of positions with the actuator in the second speed mode.

  • Systems and method for speed and torque control of a DC motor
    Patent number: 9509242
    Abstract: A method for operating a direct current (DC) motor is shown and described. The method includes generating a first pulse width modulated (PWM) signal having a first duty cycle, providing the first PWM signal as a PWM DC output for the DC motor, and adjusting the first duty cycle to control a speed of the DC motor. The method further includes sensing an electric current output to the motor using a current sensor and, when the sensed current exceeds a threshold, holding the PWM DC output off.

  • Speed adjustment of an actuator for an HVAC system
    Patent number: 9062893
    Abstract: An actuator for moving a component of an HVAC system includes a housing, a motor, and a hub configured to receive a shaft. The actuator also includes a processing circuit configured to temporarily shift the actuator from a first speed mode to a second speed mode that is different than the first speed mode upon receiving an input signal.
