We develop and produce your
individual electromagnet in our special factory in small and large series.
Schramme has been developing
and producing electromagnets since 1975. Proportional solenoids are our strength. The special challenge
here is the reduction of hysteresis.
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.
