How Does a Linear Actuator work?

Posted by 1Cary on

The Main Structure:
An electric linear actuator consists of a DC motor, a series of gear (Reduction gear), two limit switches and a Lead screw including a nut.
The Linear Actuators'enclosures:
Linear Actuators have different IP ratings. The lower the number the lower the protection is. IP-54 offers basic protection such as dust, and a higher IP-65 rating offers a water proof protection and ideal for outdoor use.

Linear Actuator Works:
An electric linear actuator is a device that converts the rotational motion of a motor into linear motion. This will provide both push and pull movements via the main extending shaft on the Actuator. This pushing and pulling action makes it possible to lift, drop, slide, adjust, tilt, push or pull things, simply by pushing a button.

Stroke Control Device:
The gear on the DC motor drives a series of gear (Reduction gear) to rotate, so that push and pull movements via the main extending shaft on the Actuator. When it reaches the maximum stroke, the limit switch is triggered to cut off the power, and the motor stops running (the push and pull movements are the same).

The electric linear actuator uses 12V / 24V DC motor as the power source. It has a matching power supply, wireless RF remote control switch and manual controller. The input voltage of the wireless RF remote control switch or manual controller is 12V / 24V, and the output voltage is 12V / 24V. The standard stroke of electric linear actuator is 50mm, 100mm, 150mm, 200mm, 250mm, 300mm, 350mm, 400mm, 450mm, 500mm, 600mm. No-load speed 5mm/s, 10mm/s and 30mm/s.

The following main factors need to be considered when selecting an electric linear actuator:
1) The linear actuator thrust, speed, travel, work environment, it may also be used according to further increase the electric linear actuators accessories such as a limit switch, Hall-effect sensors.
2) Do not overload run.
3) When a lateral force is generated during use, a guide device needs to be installed to ensure stable operation of the equipment.
