Another semester finished. Balance time and my first paper.

We finally wrapped up our group works. Yes, we dragged our feet like sloths on this one (school ended almost two months ago). Or rather, we definitely bit off more than our part-time researcher lives allow us to chew. Anyway, if you’d like to read the more or less full account of our work in […]

Genetic mangling of electric motors

July 9, 2009

6

As has been said before, we’ve taken an Intelligent Algorithm approach to our motor design framework. We started by adding a Genetic Algorithm to the MotorFemmulator project code, and left it running on a 7 computer improvised cluster. It has yielded some results, namely the optimization of a motor from 44Nm (5kW) to 200Nm (23kW) […]

Overcoming FEMM limitations

May 29, 2009

Just like any other software, FEMM has its limitations. I’ve been talking a lot to David Meeker, the author, who has been extremely kind and thoughtful in guiding me not only in the program’s usage but also in general electromagnetic modeling, while trying to sort out the modeling mess I’ve put myself and my colleague […]

Problem reduction

So, we’re still hammering the motor model in school. You can always take a peek here. We’ve decided early on to drop the Opti-Y optimization suite in favor of good old fashioned homegrown Octave scripts. On one hand, Opti-Y didn’t look friendly to Linux at all, and on the other hand we wanted to leverage […]

The wheelmotor goes to school

April 8, 2009

I finally got the chance to officially push my wheelmotor project into my master’s. By an incredible strike of luck, I teamed up with a class mate that is also extremely interested in sustainable energy and electric propulsion; not only that but he also has experience in Octave development and is keen in applying that […]

Rethinking the project

January 23, 2009

After 1 year and 2 months, I have very little to show for results. There is this software framework that produces sketchy models of wheel-motors which have no guarantee of real-world performance. And a web site full of interesting bits of information, a few intelligent discussions, and a handful of very nice and techie web […]

A new (contributed) hub motor

December 6, 2008

After a 3 week intensive sprint and with a little help from me, Pierre has finalized his own motor model and it is now available in the repository. He also contributed a couple of small tweaks to my common Lua “libraries”. The GPL wins again. 😉 I helped out as much as I could (with […]
