Electro-permanent magnets (EPMs) are pretty nifty concepts, and if you aren’t familiar with them, they are permanent magnets ...
Towards the end of July I read a post about how efficient AC induction motors are and that how using them and reducing their speed will help us all to reduce the green-house effect, save money and the ...
Researchers found friction can occur without contact, driven by magnetic dynamics, and does not always increase with load. The effect could enable controllable, wear-free technologies.
Permanent magnets can, in principle, greatly simplify the design and production of the complex coils of stellarator fusion facilities. Permanent magnets akin to those used on refrigerators could speed ...
Engineers and scientists in China have started up the first Chinese ship with a permanent magnet motor system. The system promises to make quieter submarines that are much harder to detect, a major ...
A number of readers questioned the veracity of the technology presented in this article. To address their concerns, we did a follow-up, which can be found here. Permanent magnets are an integral part ...
Controlling magnetic states in materials typically requires continuous power or only works in rare, specialized systems. Researchers developed a general theory showing how electric fields can ...
Electric motors or wind turbines are driven by powerful permanent magnets. The most powerful ones are based on the rare earth elements neodymium and dysprosium. In future, a new process route will ...
We recently published an article on the Power Electronics with the headline, “Unique Motor Uses Only Permanent Magnets – No Electric Power Required.” We received a firestorm of criticism that this ...
