## Computing Back-EMFs with space vectors

Here’s a no-brainer tip for you: space vectors are useful when designing electric motors. Duh. However, there’s one specific detail you might not know: they are also extremely handy when computing the back-EMF waveform, or induced no-load voltages. Specifically, they…

## Computing Flux Linkages in 2D

How to compute flux linkages of a coil, using the results of 2D finite element analysis. Nice to know information, with occasional professional uses.

## Optimization of an e-bike drivetrain

My guest post at Revonte.com covers the optimization of an e-bike powertrain: the benefits of a CVT transmission, along with other basic principles.

## 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?
