What are circulating currents, why are random-wound windings called random, why should you care? Find out here, with convenient bullet points!
Introduction to active magnetic bearings (AMB)
Active magnetic bearings are widely used in high-speed machines and sensitive environments both. Here’s what they are, and how they work.
How FEA works – Post-it version
No time to waddle through dozens of pages full of mathematics? Here’s how FEA works – the sticky note version! Basic math skills required.
Lagrange multipliers and their physical meaning
Lagrange multipliers are a handy way of adding constraints to an FEA problem. Be careful with them, though – or don’t trust your results.
Options for (Analytical) Torque Computation – Part 3
A commonly-used approach for torque computation utilizes the virtual work principle. Here’s what it is, and what options you have with it.
Options for (analytical) torque computation, part 2
More methods for analytical torque computation. Somewhat more advanced than previously, but still simple and fast. A little more versatile, too.
Options for (analytical) torque computation – Part 1
Analytical torque computation – aka pen-and-paper stuff. Fast, efficient, extremely enlightening – and unfortunately fairly complex, more often than not.
Options for (numerical) torque computation
Knowing the torque of an electric motor is kinda important, so it makes sense to double-check your results by using an alternative computation method.
6 Things you might not know about finite element analysis
The title says it all. 6 things you might not know about finite element analysis, but should. A bit tongue-in-cheek, but still valid info.
SMEKlib update
The SMEKlib library (open-source FEA for electrical machines in Matlab) just received a huge update. Here’s a brief rundown, plus associated rambling.
