Permanent Magnet Motors Providing Key Benefits

White drone motor close up on a black background

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…

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).…
