Holding Magnets

Electromagnets or electrical holding magnets develop high attraction forces to flat magnetic materials.

We supply both pure steel (magnetic attraction when powered up) and permanent magnet version (electrical release). Also we offer an optional spring preloaded ejector pin to overcome residual magnetism and optional armature plates as magnetical counter part for optimum performance.

products / electromagnets

Electromagnets or electrical holding magnets develop high attraction forces to flat magnetic materials. Most common versions need to be energised to develop force, like our EM series of electromagnets. The applications range from holding of ferromagnetic workpieces during machining or assembly operations, through door latching or holdback devices, safety mechnisms, to selector devices in textiles machinery.

Because the field sharply drops with the distance of the counterpart, the flatness of the surface and a very thin plating are important features. This is also true for the optional armature plates.

Options for our Electromagnets are:

  • Ejector Pin: preloaded spring pin to overcome residual magnetism, reduces the holding force by about 10%
  • armature plate (ferromagnetic, nickel plated) as magnetical counter part to the electromagnets
  • custom windings
  • permanent magnet version (electrical release)

*hot = constant temperature, which is reached in still air at constant energisation at nominal power.
After switching the power off a residual magnetism of about 5% needs to be expected.

Electromagnets General Information

products / holding magnets

As Electromagnets also Holding Magnets develop high attraction forces to flat magnetic materials - but they don't need electrical power and therefore they can't be switched off. Holding Magnet devices comprise of a permanent magnet usually in the form of a disc, encased in a mild steel pot which provides a return flux path.
