Finding the operating point of an electric motor is no longer as simple as it used to be. I mean, in the past, or in the textbooks and course slides we often see during our studies, it was simple. Just…
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?
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.
