Limit yo nan ferit, SmCo ak alnico materyèl ranfòse devlopman nan jenerasyon materyèl nan twazyèm leman pèmanan: Neyodim arc ak leman leman NdFeB se kounye a leman ki pi fò ak BH (Max) jiska 52 MGOe ak fanmi pri pi ba konpare ak SmCo ak alnico leman. Neyodim leman se tou fasil nan koupe ak fè egzèsis, pèmèt yo dwe manifaktire nan gwosè ti, ki se itil pou diminye volim nan akoupleman.

The limitations of ferrite, SmCo and alnico materials enhanced development of the third generation permanent magnet material:neodymium arc magnets NdFeB magnets is currently the strongest magnets with BH(Max) up to 52 MGOe and relative lower price compared to SmCo and alnico magnets. Neodymium magnet is also easy to cut and drill, enabling them to be manufactured into small sizes, which is helpful for reducing the volume of couplings.
