In this video, we delve into how a DC motor works! For this project, we used a series-wound DC motor originally salvaged from an electric forklift.
For some great ideas on different vehicles converted to electric, check out the listing at the EV Album! http://www.evalbum.com

This video is one segment of an instructional video I created in 2010 from a home-built electric car I made in 2008. Of course, battery and motor technology has advanced quickly since then, and affordable, commercially-built, Electric Vehicles are now a reality.

This video series covers ONE low-tech and simple way of converting a car to electric. Many of these same ideas and techniques still apply to go-karts, motorcycles, boats, and lots of other projects. We hope that you enjoy watching these videos and learn a little something from them.

A simple electric car conversion project like this one uses
A 0-5k ohm potentiometer throttle: https://amzn.to/2PwMmoD
A motor controller up to 144V: https://amzn.to/394QyUh
A DC Series-Wound motor (9-inch diameter typical): https://amzn.to/2TlqYUv
Battery Charger to match your pack voltage: https://amzn.to/2Toe0Fl
On this car, we used a simple power inlet: https://amzn.to/3abNWnI
But that also meant we needed to design a separate circuit to disable the ability to drive while plugged-in. That's a built in feature of the now standard J1772 connection used in modern commercially-built cars.
J1772 Inlet: https://www.aliexpress.com/item/4000084870080.html
You would then pair that with a standard J1772 EVSE: https://amzn.to/387ixRW
I show the internal connections you need for the J1772 communications at: https://300mpg.org/2015/03/31/the-diy-j1772-charging-adapter/

Yes, we know there's a spider in the video. People love to comment as though they are the only one who has ever seen the spider. You can now follow the spider on Twitter.
