Magnetising Fixture Winding for Magnet Ring Sensor Project

Magnetising fixture inding

Bunting’s engineering team work with companies on many magnet product designs, from concept through to manufacture.  This project focused on the feasibility of designing, manufacturing, and supplying a permanent magnet ring to produce a sinusoidally varying flux density waveform for a sensor application.  A sine wave or sinusoid is a mathematical curve that describes a…

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).…
