Toyota Develops Electric Motor Without Magnet

Toyota Kembangkan Motor Listrik Tanpa MagnetToyota Motor Corp. is developing an electric motor that does not use a magnet, in order to limit the use of rare-earth metal such as neodymium and dysprosium are expensive and hard to find.

So far, the electric motor always works using magnets based on the principles of electromagnet. Where a combination of magnets and electric currents can produce mechanical energy. This basic principle is used in all electric motors ranging from home appliances, industrial electric motors up.

The high price of rare-earth metal pushing Toyota to seek a new breakthrough to slash prices by reducing dependence on rare-earth metal. Although the so-called rare-earth metal, is actually not rare. Commonly found in coal mines, iron, aluminum as a follow-up of minerals. The issue, abortion is so small that it is not economical for the mine. That's why so-called rare-earth metal. China currently controls 90% of the production of this material. Japan is the world's largest consumer by absorbing a third of world production.

Find a breakthrough to produce an electric motor with no magnet - which took the rare-earth metal - is increasingly important. Moreover, production and demand of electric cars expected to soar in the next few years.

Because China controls 90% of the production of this material, the slightest disturbance in China will affect the production of electric motors in Japan. Moreover, China now has a third of the total reserves of the world's reserves.
