Five years ago I built the Openwheel. It's an open-source, DIY self-balancing board and I’ve decided it’s finally time to revive this project. In my last update, I did a teardown of a four-kilowatt hub motor just to see how it works, but if we’re going to make the Openwheel better, we need to actually understand how hub motors work, and more importantly, we need to be able to test them. So today, I’m building the first tool I need: a hub motor dynamometer.
