Sensor Magnets

Car Dashboard Magnetic Sensors

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…

Replicating True Radial Arc and Ring Magnets with Pseudo-Radial Arcs and Rings

Halbach Array

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).…

Carbon Fibre Containment for Magnetic Rotors

Magnetic Rotor Combo

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…
