Exhibition Success for Bunting-Berkhamsted
Exhibiting at two shows, in different parts of Europe, over the same two days, was challenging for the Bunting-Berkhamsted team, but proved exceptionally successful. Whilst Matthew Swallow managed the stand at the Cenex LCV event at UTAC Millbrook in the UK, Stefano Maiaroli and Dr Chris Riley were in Pordenone in Italy at the Coiltech…
Read MoreMagnetics Importance for Electric Vehicles at Cenex-LCV
Magnets and magnet assemblies, both essential for transport electrification, are the focus for Bunting on stand C4-106 at Cenex-LCV (UTAC Millbrook Proving Ground, Bedfordshire, UK, 23rd to 24th September 2021). In particular focus is the technique of magnetizing magnet assemblies after construction, which offers a wide range of benefits including accuracy and safety. The LCV…
Read MoreMagnetiser and Magnet Setter Export Success
Successful implementation of an overseas business development strategy has resulted in orders from Italy for a bespoke Industrial Magnetiser, complete with control cabinet, and a Magnet Setter. Bunting’s UK engineering design team will design, build and test the magnetisers, control and magnet setter. Industrial Magnetisers and Magnet Setters enable the charging of both permanent magnets…
Read MorePermanent Magnet Motors Providing Key Benefits
Permanent magnet motors are electric motors using permanent magnets in addition to windings. Such motor designs are more efficient than induction motors or motors with field windings for certain high-efficiency applications such as electric vehicles and small electric motors such as found on drones and in car windshield wipers. Both AC and DC motors benefit…
Read MoreEverlube Coating Protects Neodymium Magnets
The new Everlube anti-corrosion magnet coating combats the increasingly arduous working environments for magnets and magnetic components. The Everlube coating prevents oxidation and deterioration of high-powered permanent neodymium rare earth magnets. The Everlube coating was originally developed as a brand of dry film lubricant products specifically designed to enhance and improve the performance of critical…
Read MoreAn Introduction to the Halbach Array
Halbach Arrays feature in many common-day devices such as brushless DC motors and even the Inductrack Maglev train. The Halbach Array is a specific arrangement of permanent magnets that cancels the magnetic field to nearly zero on one side, but significantly increases the strength of the magnetic field on the opposite side. This magnetic phenomenon…
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 MoreMetal Recovery from Electric Vehicles
Mining the Urban Environment The anticipated global increase in production and consumption of electronic goods and electric vehicles puts a huge strain on raw material reserves. Subsequently, the focus has turned from mining raw materials to reclaiming, reusing and recycling secondary materials. This is known as ‘Mining the Urban Environment’. The strategic nature of critical…
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…
