MIT foot scooter with homemade hub motors

By Jerome, 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.

http://web.mit.edu/first/scooter/

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.

I have been searching the web for all kind of interesting stuff and found many good things.

Lately I have been following thread of this forum

This forum is a gold mine for people studying and making electric vehicule.

When searching, I found this thread

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.

Motor connections

By Jerome, October 27, 2009 5:27 pm

When I first installed the motor, I really wanted to test it. I did not have a motor controller so I when to see the guys from www.vamudes.com to borrow one of there 60Amp ESC controller. They did not have “gold bullet connectors” they had normal terminal connector.

I had to remove the “gold connectors” from the motor to change them with blue terminal connectors.

You don’t want to cut those wires, each individual wire strand is covered with thin insulation. The insulation of each tip was remove. So if you cut the wire, you will need to remove the insulation. I recommend high power soldering iron , this  will melt the insulation. I use to take a open flame to burn the insulation… not good, the wire was black and was hard to solder.

The connectors are now crimp to the wire.

I was now ready to test my super scooter.

As we speak,  I have my controller and I soldered back the originals gold connectors.

Maker faire 2009 push scooter

When I was at the Maker faire 2009, I saw this neat scooter modification. I was able to ride it. It was awesome, the front wheel make the entire ride smooth and very stable. The ride was amazing!

It is so great, that I took picture just in case I wanted to build one :) Then I realise that I could make one using the same electric motor I have :)

Back in Québec, I was able to find a razor push scooter for 1.50$ and a kid bike for 1$ at garage sell! The wheel on the kid bike is around 12 inch and I was planning to make it using a small wheel. I still want something portable if I enter a city bus or something like that.

I was also able to find a electric scooter for 18$.E100_electric_scooter_ 001
