What are BLDC motors? And how do they differ from AC motors? Why do people keep using such contradictory terms and confusing us?
Induced eddy currents in sheet – SMEKlib example
Video of induced eddy currents in a lamination steel sheet – plus how they can be computed. There’s a SMEKlib example too for you to try!
Maglev Systems – How to model them analytically?
Maglev – magnetic levitation – systems can be quite different from electric motors. So how to model them without time-consuming 3D simulations?
Poynting vector and motor design
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.
