## 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.

## 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.
