A wind energy conversion system needs a maximum power point tracking strategy. In the literature, several works have interested in the search for a maximum power point. Generally, their goals are to ...

Abstract Optimal control of large-scale wind turbine has become a critical issue for the development of renewable energy systems and their integration into the power grid to provide reliable, secure, ...

ABB secured orders from shipbuilders in China and South Korea to equip 18 and 12 liquified natural gas (LNG) carriers, respectively, with permanent magnet shaft generator technology. The ships are due ...

The high-energy-product neodymium rare-earth permanent magnet (RE-PM) was discovered in the early 1980s. Later, dysprosium doping emerged to provide reasonable RE-PM magnetization life by sacrificing ...

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 ...
