Japan develops vehicle motor free of rare earths

Tokyo, Japan (AFP) Sept 30, 2010
Japanese researchers said Thursday they had developed a hybrid vehicle motor that is free of rare earths, the minerals that are now almost exclusively produced by China.

The news from a state-backed research group and a university comes days after industry sources said China had temporarily halted crucial rare earth exports to Japan amid a bitter territorial dispute.

Magnets made from rare earths have so far been considered indispensable for motors in gasoline-electric hybrid and electric vehicles produced by Japanese auto makers such as Toyota, Mitsubishi and Honda.

Japan's New Energy and Industrial Technology Development Organisation (NEDO) and Hokkaido University said they had now developed a motor using magnets which are commonly used in electronics parts.

"As the technology uses only inexpensive ferrite magnets, it is expected to boost Japan's competitiveness in the development of next-generation automobiles contested more and more fiercely in recent years," they said in a statement.

Kenji Kobayashi, of NEDO, said "ferrite magnets are very cheap as they are mostly iron."

Ferrite magnets are weaker than magnets made from rare earths such as neodymium and dysprosium, which are both imported from China, but sell at only one 20th of their price, he told AFP by telephone.

"Magnets are placed differently in the new motor so that their attraction power does not escape," Kobayashi said, adding however that it would take years to put the technology to practical use.

More than 90 percent of rare earths worldwide are produced in China.

China's rare earths shipments to Japan were disrupted last week amid a bitter diplomatic spat between the two countries, although China has moved towards resuming exports, according to industry sources.

Beijing repeatedly denied claims it blocked the shipments of rare earths, which are used in a range of products from consumer electronics to batteries for hybrid cars and components in wind and solar power.

Electric Cars Hold Greater Promise For Reducing Emissions And Lowering US Oil Imports
Dallas TX (SPX) Sep 29, 2010
Electric cars hold greater promise for reducing emissions and lowering U.S. oil imports than a national renewable portfolio standard, according to research conducted by Rice University's Baker Institute for Public Policy. This assessment is among several contained in a new major policy study the Baker Institute Energy Forum will release at a Sept. 27-28 conference titled "Energy Market Con ... read more
