Before the discovery of the neodymium magnet, the strongest permanent ... “At that time, all these motors used ferrite magnets, which are low-performance magnets,” he says.

Permanent magnet is an object made up of ferromagnetic material, which has magnetic properties and creates its own magnetic field. Permanent magnet motors are manufactured using permanent magnets in ...

Permanent magnet motors, as the name suggests, use magnets on the rotor that are typically made using rare earths, with neodymium taking the largest fraction (although there has been some progress in ...
