Methods and systems include an actuator adapted to provide drive power and hold power to an external device. A motor provides for driving the external device to a determined position when the motor is energized. A switching circuit is configured to energize the motor with a high voltage to drive the external device to the determined position and energize the motor with a low voltage to hold the external device in the determined position.

Systems and methods for damper actuator without microcontroller

An actuator arrangement having a rotational output includes a power input, a motor, at least an intermediate gear, a solenoid and an output. The power input connects to a source of electrical power. The motor has an output shaft including a worm gear. The motor is operably connected to the power input. The motor and output shaft are rotatably connected to a housing of the actuator. The output gear generates a rotational output at an axis thereof, and is operably coupled to be driven by the at least one intermediate gear. The solenoid is operably connected to the power input, and includes a piston member. The piston member has an actuated and a non-actuated position. The piston member in the actuated position urges the worm gear and the at least one intermediate gear into meshing connection.

Actuator arrangement with worm gear and rotational output having an encoder

A damper actuator assembly comprises a gear train including a follower gear. The follower gear is arranged such that the position of the follower gear indicates the position of at least one blocking member of a damper that the actuator is connected to. A sensor is positioned within the damper actuator and is configured to monitor the position of the follower gear. Accordingly, the sensor is configured to provide an electrical signal indicative of the position of the follower gear to a processor. A driving member is connected to the gear train and is configured to drive the gear train at two or more variable speeds depending on the electrical signal provided to the processor from the sensor.

Damper actuator assembly with speed control

A first embodiment is an actuator arrangement having a rotational output and a motor. The actuator arrangement further includes at least one intermediate gear, an output gear, and an encoding detector. The motor has an output shaft that includes a worm gear. The output gear generates a rotational output at an axis thereof. Position encoding indicia are fixedly arranged on the output gear. The encoding detector is disposed in position to detect the position encoding indicia.

An actuator includes at least one drive arrangement configured to generate output mechanical power from input electrical power. The actuator also includes a communication line input port and a control unit. The communication line input port is configured to connect to a communication line, and is configured to obtain electrical power from the communication line. The control unit is configured to obtain first information from the communication line via the communication line input port, and is further configured to adjust the operation of the at least one drive arrangement based on the first information and based upon information identifying electrical power available for use as input electrical power.
