To open trapdoors of different weights, it is necessary to select a linear actuator with suitable thrust, stroke and speed. The picture below is a trapdoor installed horizontally with a length and width of 80 cm. Its weight is 40kg. Choose the suitable stroke: We recommend that you install the bottom and head of the linear actuator at a distance of about 40cm vertically and horizontally from the fulcrum of the trapdoor. In this way, the initial installation distance between the head and the bottom of the linear actuator can be calculated to be 57CM. When the trapdoor is opened...

The linear actuator slide controller with slide potentiometer is used to control to control the travel of 12V electric linear actuators. It comes with travel control knob switch and learning button and external 10K sliding potentiometer. It is suitable for linear actuators type A2 with internal potentiometer. The operation of linear actuator with controller : Toggle the toggle switch to the right, which means the linear actuator is controlled by the knob switch. Toggle the toggle switch to the left, which means the linear actuator is controlled by the slide potentiometer. 1) The operation by the knob switch: Turn the...

Medical technology Medical technology exists in hospitals that put in place mechanical gantries to move the equipment around and control motion with remote controls. For example, a gantry system can be used to move an MRI machine with the push of a button in the medical industry, actuators are used to control mechanical systems like surgical tools or manipulators. This makes it possible for surgeons to perform more precise motions. Medical devices also use electronic actuators to perform tasks like opening and closing valves.   Automotive Automotive actuators control the movements that occur in cars. They can also control other...

The basic working principle of electric linear actuators is to convert the rotary motion into the linear motion. This conversion of motion is done with the help of a gearbox and a lead screw. They are three most important parts of electric linear actuators. The electric linear actuator is composed of 5 main components: motor, limit switches, lead screw, gears set and stroke rod. Motor: This is one of the most important components of linear actuators, which actually provides rotational movement. Usually 12 volt DC or 24 volt DC motors are used, and sometimes AC motors are also used, it...
