The Beginning Of The End For Rare Earth Permanent Magnet Motors?
Okay, okay, so maybe I’m exaggerating just a little… but if the news from Japan today is anything to go by, perhaps we’re not far off. According to a report at TradingMarket.com, Japan’s Daikin Industries has teamed up with Professor Shigeo Morimoto from Osaka Prefecture University, to create an electric motor that produced high torque [...]

Monday, September 14, 2009
Yesterday I posted an article over at RareMetalBlog with the above subject line. The Rare-earth Information Center was established in January 1966, at the Ames Laboratory in Ames, Iowa. It was a great resource for industry, government and academia with its database of papers, reports, patents, conference proceedings, news and other information on rare earths. It [...]

Sunday, September 13, 2009
Whenever I read articles in the media on neodymium-based [Nd-Fe-B] permanent magnets, I’m always interested to see how much historical detail the writer includes on the subject. The majority of writers either make no mention at all of the origins of Nd-Fe-B, or will mention only that it was developed by General Motors in the [...]

Tuesday, September 1, 2009
In recent days we’ve seen a flurry of activity concerning reports that the Chinese Ministry of Industry and Information Technology has called for a total ban on foreign shipments of certain rare earths elements. These reports also claim that other rare earth metals including neodymium, would be restricted to a combined export quota of 35,000 [...]

Friday, August 28, 2009
Earlier today, I posted an article over at RareMetalBlog after the question of non-defense applications of rare earth permanent magnets came up. Certainly most of us are aware of the use of such materials in motors and generators, but there are hundred of other applications for such magnets – and not just in the form [...]
