Bunting Magnetics’ Range of Permanent Electro Holding Magnets

Our Permanent Electro Holding Magnets include a permanent magnet, encapsulated in a magnetic housing with an excitation coil wound between the magnet and the housing. Just like an electromagnet the magnetic circuit has to be switched on and off and the permanent magnet within this design means that the magnetic circuit is open in the switched off state and therefore generates a holding force without the need for constant application of current. This means that there is safe holding of workpieces, doors or other components in the event of a power failure or when there is the need for holding components for long periods of time.

When the coil is energised with a DC current the magnetic field from the magnet is negated and the part being held can be taken away with a minimal amount of effort, Some residual pull force will remain, unlike in an electromagnet and this needs to e taken into account when designing the complete system. These Permanent Electro Holding Magnets are incredibly energy efficient as they only need a brief pulse of energy to switch states.

If you do not see a shape or size or performance of Permanent Electro Holding Magnets that you require, please get in touch as we can design one to suit your needs.

Please Note : Only to be used when in full face to face contact with a section of magnetic material as a gap of only 0.1mm will result in a drop off in performance of around 90%. This includes paints and non-magnetic coatings.
