Testing the velleman controller Part 2 - Video

Final Electronics Configuration

Final Electronics Configuration

I just finished correcting the configuration of the electronic components for our scale model.

I am very glad that it worked out! The motor accelerates when we turn the potentiometer and comes back to a stop when the “pot-meter” returns to “position zero”.

I am quite curious to what will happen when we start using big motors which we will actually be using in the future. Can we develop an open source controller for electric motors? Are there are people developing something like that??

It is probably wiser to use one of the existing controllers like the Alltrax Controllers but I would be quite curious to understand what makes up a robust motor controller.

Next Steps: Design the Laser Cut scale frame to contain all components (battery, pot-meter, motor and Board)

First sketch of a test model for the electronics

Here are my quick thoughts on paper, for a scale model, a platform to understand the electronics of a basic electric vehicle. Even at a small scale, working on the main components will make a lot of the terms and specifications of the electronics more clear to understand.  My goal with this exercise will be to build from scratch the electronics needed to accelerate the motor when a potentiometer is turned. For that I will choose one of the tiny motors Kees have given me.

For the controller, Kees also suggested me to use a building kit like the DC to pulse modulator K8004 from Velleman. But I know that the open source boards from Arduino could also do the job, i just don’t have clue which one of them. Does Anyone one know the Arduino board model that could be indicated for controlling this little model I want to build?

In order to hold everything together, I am thinking of making a little frame resembling a frame of a motorcycle, with the rear wheel turning. The frame shall be cnc lasered from a 2mm thick plexiglass/metal/wood sheet of about 200 by 300 milimeters (the exact measurements may vary slightly from that)

Any company willing to sponsor the laser cut parts?

Tiny Electric Motors

Posted by Henrique Monnerat on April 10th, 2009

After watching the 24 Hours of Electricross video, I am so looking foward to starting the second phase of this project. I decided that it can be a really exercise to build test model with the main electronics components and get a better understanding of the electric terms that make up an electric vehicle dictionary.

In a conversation with Kees, a fellow engineer at Flex, I got some support on relevant information about building a small test model on the electric components. Yesterday he surprised me with these motors! saying I could use one of them for the test!

Thanks Kees, really nice incentive.
