Permanent electro holding magnets consist of a permanent magnet that is installed into a magnet housing together with an excitation coil. The magnetic circuit, which is open in the switched-off state, allows for currentless and safe holding of magnetic workpieces. When the DC-excited coil is switched on, the permanent-magnetic field is neutralized at the holding surface, and the workpiece to be held can be taken off. These magnetic systems are very energy-efficient as the magnet is only briefly energized to release the workpiece. They are used in particular if there are long holding times without energy consumption and where loads must be reliably and safely held in case of power failure.
Kendrion offers the following standard models:
Series 01 320: Permanent (electro) holding magnets in a round design with a diameter of 20-150mm
Series 01 310: Permanent (electro) holding magnets in rectangular design in lengths of 150 and 200mm
Series PEM: Permanent (electro) holding magnets in a round design with a diameter of 12-25mm. A threaded rod at the rear side is available for installation.
The magnets achieve the maximum holding forces possible if the armature plate rests directly and to the full extent on the surface. The holding forces reach from 8-3,500 N.
