What are circulating currents, why are random-wound windings called random, why should you care? Find out here, with convenient bullet points!
Active magnetic bearings are widely used in high-speed machines and sensitive environments both. Here’s what they are, and how they work.
A commonly-used approach for torque computation utilizes the virtual work principle. Here’s what it is, and what options you have with it.
More methods for analytical torque computation. Somewhat more advanced than previously, but still simple and fast. A little more versatile, too.
Analytical torque computation – aka pen-and-paper stuff. Fast, efficient, extremely enlightening – and unfortunately fairly complex, more often than not.
Of mechanics in electrical machines, torsional vibrations are often the most critical. Read here to learn the basic principles, and how to analyze them.
Vibrations in electrical machines can be divided into several categories, differing on the mechanism and type of vibrations produced.
Nicola Chiodetto is a PhD student at the Newcastle University developing superpowered electric motors for aircraft use. Read his interview here.
The magnetic forces in an electrical machine deform it, and the mechanical stresses influence the magnetics. Read more about this interaction here.
Alright, everyone’s seen electric cars. But what about electric aircraft? Who’s making them, and more importantly: why? Some challenges and benefits here.
