What is consist of radiant electric actuators?

The structure of a radiant electric actuator may vary depending on the specific model and manufacturer. However, most radiant electric actuators generally consist of the following main components:

    Motor: The actuator is powered by an electric motor, which converts electrical energy into mechanical motion. The motor is responsible for driving the actuator's output shaft or gear mechanism.

    Gear Mechanism: In many radiant electric actuators, a gear mechanism is used to convert the rotational motion of the motor into linear or rotary motion. The gear mechanism provides the necessary force and torque to actuate the valve or damper.

    Housing: The actuator is enclosed in a housing or casing, which protects the internal components from environmental factors and provides mechanical support. The housing is typically made of durable materials, such as metal or high-strength plastics.

    Control Circuitry: The radiant electric actuator includes control circuitry that receives and interprets control signals from a building automation system or thermostat. The control circuitry determines the actuator's position and regulates the motor's operation accordingly.

    Output Shaft: The output shaft extends from the actuator and is connected to the valve or damper. As the motor rotates or moves, the output shaft transfers this motion to the valve or damper, controlling the flow of fluid.

    Position Feedback Sensors: Some radiant electric actuators incorporate position feedback sensors, such as potentiometers or encoders, to provide information on the position of the valve or damper. These sensors allow for accurate positioning and control of the actuator.

    Mounting Bracket: To facilitate installation, radiant electric actuators often feature a mounting bracket or plate. This bracket allows for secure attachment to the valve or damper and ensures proper alignment and operation.

    Electrical Connections: The actuator has electrical connections for power supply and control signal input. These connections may include terminals or plugs for connecting the actuator to the building's electrical system and control devices.
