The Poyinting vector is quite rarely used in electric motor design. However, this underutilized tool can be extremely useful in the right hands.
Matlab versus Python – in numerical analysis
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.
Video: Circulating and eddy currents with PWM supply
Circulating and eddy currents combined with PWM supply, illustrated with a nice video. What more could you wish for, really?
How a self-levitating motor works
An active magnetic bearing system can be directly integrated into an electric motor, resulting in a self-levitating motor. Here’s how it works.
Introduction to 3D Magnetics – with SMEKlib
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.
Circulating currents – Post-it version
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.
