EVERYTHING YOU SHOULD KNOW ABOUT Solenoids
What is an solenoid?
Solenoid (electromagnet) is an umbrella term for all types of electromagnetic actuators. It consists of a coil of electrically conductive wire through which a current flows.
As soon as the current flows through the coil, a magnetic field is generated around the coil. The strength of the magnetic field depends on the strength of the current flowing through the coil and the number of turns in the coil.
Depending on the design, the magnetic force of the solenoid is used to perform linear & rotational movements or to apply holding forces to components, thereby fixing or braking them.
An Solenoid comes in different types:
Solenoids, Holding Solenoids, Bistable Solenoids, Reversing Solenoids, DC Solenoids, Electromagnet Valves, Twin Solenoids, Switching Solenoids, Electromagnetic Clutches, Miniature Solenoids, Proportional Solenoids, Spreading Solenoids, Braking Solenoids, Permanent Holding Solenoids, Locking Solenoids and other special solenoids for various applications.
Most of our products are custom designed and then mass produced.
Advantages of solenoids?
A major advantage of solenoids is their strength. Significantly greater magnetic forces can be applied with an solenoid than with classic permanent magnets. This makes them ideal for applications that require a high magnetic force.
Furthermore, solenoids impress with their versatility. They are used in a wide variety of applications. From excavators to church organs, from escalators to drilling machines, from trucks to summer toboggan runs - magnetic technology can be found almost everywhere.
Controllability is also an advantage, as solenoids can be controlled precisely and quickly, making them ideal for applications where fast and accurate control of magnetic force is required.
Another strength of solenoids is their efficiency. They only consume power when they are switched on. Permanent magnets, on the other hand, always have a magnetic force and are difficult to control and turn off.
