Correlated Magnetics Research Launches “Programmable” Permanent Magnet Materials

4. October 2009

I saw an intriguing news item over at the Magnetism & Electromagnetics Interest Group yesterday, and I see that it’s starting to make its way into the press. The Huntsville Times is reporting that “Larry Fullerton, formerly of Time Domain, has developed a process to ‘program’ magnetic and electromagnetic materials so they will only attract [...]

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 [...]

The Windbelt: A New Non-Turbine-Based Wind Energy Generator

Earlier this week I came across a rather interesting new technology from Humdinger Wind Energy, LLC. Based in Honolulu, this company claims that “from enabling smart buildings to reducing the cost of wind energy”, they are “researching & developing the world’s first non-turbine harvesting technology, the Windbelt™ generator”. Wind power without a wind turbine? Definitely [...]

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 [...]

New Mixed Rare Earth Permanent Magnet Material Shows Promise

Recently I came across a May 2009 presentation published by the US Department of Energy’s [DoE] Ames Lab, on a new mixed rare earth-based [MRE-Fe-B] permanent magnet [PM] alloy, for high temperature applications. The work forms part of the DoE’s multi-year FreedomCAR project, with a number of specific goals: Production of magnet materials for PM [...]

At the Magnetics 2008 Conference in Denver, I presented a paper titled “Going Green: The Growing Role of Permanent Magnets in Renewable Energy Production and Environmental Protection“. Earlier today I finally uploaded a copy of the presentation to the Web, which you can now find here. The presentation covered a range of related topics, starting [...]

Permanent Magnets For Wind Turbines: An Alternative Viewpoint

28. July 2009

7 Comments

In the Summer 2009 edition of Magnetics Business & Technology, Tony Morcos of ACM Magnetics wrote an excellent article that dissects the growing conventional wisdom that near- and medium-term future growth in wind turbine production, will lead to vast shortages of neodymium-based [Nd-Fe-B] permanent magnets. Tony points out that permanent magnets are just one option [...]

The BBC reported today on a system that can deliver power to electrical and electronic devices at significant distances away from the source, without the need for wires or cables. Eric Giler from Witricity demonstrated the use of the system to charge cell phones and other devices during the TED Global event in Oxford, UK. [...]
