Scientists develop high-performance permanent magnet without expensive heavy rare earth elements
The Nano Materials Research Division at the Korea Institute of Materials Science (KIMS), led by Dr. Tae-Hoon Kim and Dr. Jung ...
Damping vibrations is crucial for precision experiments, for example in astronomy. A new invention uses a special kind of magnets to achieve this -- electropermanent magnets. They consist of a ...
Kongsberg Maritime has announced the introduction of two new sizes to its Underwater Mountable, Permanent Magnet (UUC PM) ...
Wind Engineering, Vol. 19, No. 6 (1995), pp. 303-324 (22 pages) Based on the optimal shaft speed control concept for wind turbines, this paper develops an algorithm and controller structure to ...
Magnetic couplings transmit high torque with no physical contact, and they disengage smoothly when load gets too high. Generally speaking, the couplings use magnetic power in three different ways; ...
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 ...
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 ...
