What is an actuator?

An actuator is a device that can set systems and/or other devices in motion. An actuator does this by means of a control signal and needs an energy source. The control signal requires relatively little energy to operate. It can be controlled by electrical voltage or current or can even be pneumatic (air pressure) or hydraulic fluid pressure.

An actuator is a mechanism that controls a control system to perform an action or task. The control system can be simple (a fixed mechanical or electronic system), software-based (for example, a printer driver, a robotic control system), human or other input.

There are several types of electric actuators, including linear actuators and rotary actuators. Linear actuators produce linear motion, such as sliding or pushing, while rotary actuators produce rotational motion, such as turning.

Electric actuators are widely used in a variety of applications, including industrial automation, robotics, HVAC systems, medical devices, automotive and more. They often provide precise and controlled motion, and can be controlled by various electrical signals, such as voltage, current or pulse width modulation.

12v and 24v linear actuator

A linear actuator is an electrical device that allows a rotational motion in low-voltage motors to be converted into a push or pull motion. The best known is its class is the CON35 this is a high efficiency inline electric actuator.

How does a linear actuator work?

A linear actuator is a device used to create linear motion, meaning it can move objects in a straight line, usually from point A to point B. It works based on different mechanisms, but the most common type is the electric linear actuator. Here is a general explanation of how an electric linear actuator works:

1. **Electric motor**: The linear actuator contains an electric motor, which can be driven by direct current (DC) or alternating current (AC). This motor converts electrical energy into mechanical energy to generate motion.

2. ** Gear mechanism**: The electric motor is connected to a gear mechanism that converts the rotational motion of the motor into linear motion. This gear mechanism may consist of various components, such as gears, threaded shafts, spindles, and so on, depending on the specific design of the actuator.

3. **Spindle or threaded shaft**: One of the most common components of the gear mechanism is a spindle or threaded rod. When the motor rotates, it turns the spindle, causing it to move forward or backward, depending on the direction of rotation of the motor.

4. **Fixing Point**: An attachment point is attached to one end of the spindle, which is connected to the object to be moved. When the spindle rotates, the attachment point is moved along the spindle, moving the object linearly.

5. **End stops**: Some linear actuators are equipped with end stops to limit movement to a certain range. These end stops may be mechanical or electronic and prevent the actuator from exceeding the intended range of motion.

6. **Control system**: The linear actuator can be controlled by a control system, such as a switch, remote control, programmable controller or computer interface. This allows the user to control the direction and speed of movement of the actuator.

In short, a linear actuator converts electrical energy into mechanical motion to move objects in a straight line, and it works through a combination of an electric motor, gear mechanism and a spindle or threaded rod.
