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.
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 – magnetic levitation – systems can be quite different from electric motors. So how to model them without time-consuming 3D simulations?
The Poyinting vector is quite rarely used in electric motor design. However, this underutilized tool can be extremely useful in the right hands.
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.
Circulating and eddy currents combined with PWM supply, illustrated with a nice video. What more could you wish for, really?
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.
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 are a handy way of adding constraints to an FEA problem. Be careful with them, though – or don’t trust your results.
Knowing the torque of an electric motor is kinda important, so it makes sense to double-check your results by using an alternative computation method.
