The progress of Energy Magnetics to improve Motor Energy efficiency

摘要

The energy supply problem becomes very serious day by day due to background that the world economy is getting huge by shifting from the developed nations economy of 700 million people to the global economy with 7 billion people. The manufacture of automobiles, home appliances and information devices is exploding twice after 20 years. In order to solve energy supply problem, new research into electric vehicles, energy efficient appliances, renewable energy, and the smart grid has been progressing rapidly. In automotive field, a lot of applications of motors expand by replacing from the engine, the hydraulic machines and small devices operation of which three categories on motors applications are shown in Fig.1.
