Best electric Motor for go Kart

Electric Motors / June 6, 2017

Growing up in the 70s and 80s, a go-kart was a quick ticket to coolness, second maybe to a mini-bike. In both cases, a welded steel tube frame and a cast-off lawnmower engine were all that stood between you and neighborhood glory. Looks like a couple of engineering students caught the retro juvenile delinquent bug and built this electric go-kart for their final project.

While the frame for [Adrian Georgescu] and [Masoud Johnson]’s build was a second-hand find, the powertrain is all custom. They targeted a power output of 3 kW but found no affordable motors in that range. So, in true hacker fashion, they rolled their own motor from a used Subaru alternator. The three-phase motor controller came from an electric scooter, three LiPo packs provide the juice, and a pair of Arduinos takes care of throttle control, speed sensing, and sending data to the virtual dashboard on an Android phone. Some lights and a snappy red and black paint job finished off the build. While the video below shows that the acceleration isn’t exactly neck-snapping in the Tesla style, the e-kart can build up to a good speed – 53 km/h. Not too shabby, and no deafening engine right behind your head.
