Abstract:
Methods are provided for forming/inserting a magnet in a rotor. One method includes coating a plurality of magnetizable particles with a non-metallic material, inserting the coated particles in a rotor, and magnetizing the coated particles. Another method includes inserting a plurality of magnetizable particles into a rotor, submersing the rotor in motor varnish to coat the particles with motor varnish, and magnetizing the particles. Yet another method includes inserting a plurality of magnetizable particles in a rotor, inserting a non-metallic material into the rotor, mixing the particles and non-metallic material to form a mixture, curing the mixture to coat each particle with non-metallic material, and magnetizing the particles. Still another method includes mixing a plurality of magnetizable particles with a non-metallic material, curing the non-metallic material to coat each particle with non-metallic material, inserting the coated particles in a rotor, and magnetizing the coated particles.
