Introduction of AS 0925 New Design Linear Solenoid Actuator
A tubular solenoid is an electromechanical device that converts electrical energy into mechanical motion. The following is a detailed introduciton :
Linear Solenoid Actuator Structure
Solenoid Coil: It consists of a copper wire coil, usually wound around a platic bobbin in the shape of a tube. The coil is often made of copper wire to ensure good electrical conductivity.
Plunger: Inside the coil-core assembly, there is a movable plunger, typically crafted from a magnetic material like soft iron2. The plunger can move axially within the tube.
Working Principle
Magnetic Field Generation: When an electric current passes through the solenoid coil, it generates a magnetic field according to the principle of electromagnetism. The magnetic field lines are concentrated inside the tube, creating a relatively strong magnetic field environment.
Plunger Movement: The magnetic field exerts a force on the plunger. In a pull solenoid, when the coil is energized, the plunger is drawn into the coil; in a push solenoid, the plunger is pushed out of the coil. This movement is used to perform various mechanical tasks.
Types Of Linear Tubualr Solenoid
Push Tubular Solenoid: When energized, it pushes the plunger out of the coil. It is typically used in applications where a component needs to be moved away from the solenoid, such as propelling a ball in a pinball machine2.
Pull Tubular Solenoid: It pulls the plunger into the coil when powered on. They generally have a longer stroke length and are more commonly used, for example, in door locks to pull the latch into place2.
Linear Solelnoid Actutator Applications
Automotive Industry: Used in power door locks, automatic transmissions, and starter motors2.
Healthcare Sector: Play a vital role in medical devices such as ventilators and patient beds2.
Industrial Automation: Employed in assembly lines, robotic systems, and sorting machines2.
Home Appliances: Found in washing machines, dishwashers, and refrigerators to control water flow and other mechanical operations2.
Safety Systems: Utilized in fire suppression systems to control the release of fire-extinguishing substances and in anti-lock braking systems in vehicles to modulate brake fluid pressure.
