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.
Late 2017 Review
No matter what happened globally, on my personal level 2017 was a great year. Here’s a short rundown of the highlights, and what’s next.
Stability of Torsional Vibrations
Torsional vibrations lead to oscillations in the electromagnetic torque, too. These may dampen the vibrations, but they may also do the exact opposite.
