Read MoreBunting-Berkhamsted 2020 Review
On January 1st, nobody could have predicted the challenges businesses would face in 2020. Despite the restrictions and obstacles presented by the Covid-19 pandemic, companies adapted and continued to design and manufacture as they supported customers. December provides the ideal opportunity to reflect on many of Bunting-Berkhamsted’s positive news stories shared in 2020. A Positive…
Read MoreSensor Magnets
Sensors are used everywhere from vehicle engine management systems to Smartphones determining if the flip cover accessory is closed. Modern everyday life would be very different without sensors and the operation of many of these sensors rely on magnetism. As products evolve, so have the range and specification of sensor magnets. A magnetic sensor converts…
Read MoreReplicating True Radial Arc and Ring Magnets with Pseudo-Radial Arcs and Rings
The manufacture of anisotropic radially magnetised arcs and rings is significantly different to the production of diametrically magnetised rings and arcs. Radially aligned and magnetised anisotropic arcs and rings are only possible in fully dense sintered NdFeB and need a dedicated press tool and magnetising fixture and have a limited physical envelope (Max OD 85mm).…
Read MoreSurface Mounted Arc Magnets
Bunting is capable of supplying almost any shape and size of a permanent magnet, but one of the most popular shapes is the arc. Arc magnets are used in a wide range of magnet assemblies, but in particular, surface mounted electric machines. There are four main types of arc magnets and these are: Each arc-type…
Read MoreBespoke Pot Magnet Design for Oil and Gas Application
An international Oil and Gas company turned to Bunting when investigating designs for a novel magnetic system to act as a pressure relief valve. The Pot Magnet assembly design requirements were complex with a number of significant technical challenges. The initial design evaluation identified that the bespoke magnet assembly would be based on a simple…
Read MoreCarbon Fibre Containment for Magnetic Rotors
Magnetic rotors are used in a wide range of applications including motors, generators, alternators and Eddy Current Separators. These rotors spin at very high speeds and a key design consideration is ensuring that the motors do not become detached from the magnet carrier. One of the key design considerations is the resultant centrifugal force. Centrifugal…
