Permanent Magnet Motors - PMDC
Experts say the single most important advance in permanent magnet (PMDC) motor technology was the introduction of neodymium magnetic materials in the mid-1970s. Samarium-cobalt and, to a lesser extent, neodymium has replaced AlNiCo and ferrite materials in many motors. Though neodymium magnets cost
