Researchers at the University of Cambridge, in collaboration with colleagues in Austria, report that tetrataenite, a “cosmic magnet” that takes millions of years to develop naturally in meteorites, can potentially be used instead of rare earth materials in magnets. Previously, attempts to make tetrataenite in the laboratory have depended on … [continued]
The shape of the longest railroad bridge in South Korea has inspired University of New South Wales engineers to design a new high-speed motor. The prototype interior permanent magnet synchronous motor (IPMSM) has achieved speeds of 100,000 RPM, making it the world’s fastest interior permanent magnet synchronous motor. IPMSM motors … [continued]
Pitt Researchers Partner with Powdermet Inc. to Design More Sustainable Electric Machines for the Department of Energy
There’s a lot of fluff out there regarding “futuristic” wind turbines. (See here, here, here, here, and here for example.) The thing is, when it comes to financial competitiveness, nothing seems to come close to the three-blade, horizontal-axis wind turbine design that dominates the market. That said, the design of … [continued]
