Low Cost High Performance SMC Motors - From Material to Application

Abstract

New technological developments are often generated from breakthroughs of fundamental research, such as novel materials. The discovery of the NdFeB permanent magnet (PM) is a good example. Because of its high remanence and coercivity, electrical machines made of NdFeB PM can be much smaller, lighter, and more efficient than the conventional ones. Nowadays, PM motors are widely used in various types of drive systems.
