Matlab and Python are both popular languages, but which one is better? You won’t find an explicit answer here, but a few factors to consider.
Circulating and eddy currents combined with PWM supply, illustrated with a nice video. What more could you wish for, really?
An active magnetic bearing system can be directly integrated into an electric motor, resulting in a self-levitating motor. Here’s how it works.
Ever wondered how 3D magnetics works, with finite element analysis? Now you can learn, with a simple SMEKlib example. The maths is anything but, sorry.
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.
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 are a handy way of adding constraints to an FEA problem. Be careful with them, though – or don’t trust your results.
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.
