MIT foot scooter with homemade hub motors

By , November 20, 2009 8:00 am

I was surfing the web and found this awesome build by some guys at MIT. They made this scooter during a summer engineering workshop.

They design and made there own 590W hub motor. Not only one motor but 2 motors! 2 wheels drive scooter!

Me and my friend Jérôme ( yes, one of my good friend is also name Jérôme and we always work together so it is Jérôme² ) are thinking/planning of making our own hub motor for a scooter.  On the BWD scooter website, there is some pretty good info and mathz equations to make your own. Worth looking into.

This is pretty darn sick! Those motors are really powerfull.

Check out my project I made for Solarbotics. It is a rolling robot inside a plastic ball.

You can also make some graph  that can be useful.

You can enter all your info about vehicule to get some pretty good result. It give a good idea on the speed you can achieve. I am still skeptic about the distance I can go with the scooter compare to what the simulator told me. That is something I will be testing when I get my new motor.

Member swbluto is the creator of the simulator you just saw. He is also making a electric scooter.
