Electric Cadet Go-Kart

Postby geekygrilli » Mon Jun 07, 2010 9:26 pm

I had a bit of a tinker on my daughters' kart tonight...

Took apart a 24v FWD mobility scooter, chopped up the front end, made a sprocket adaptor, modified some old engine mounts, and came up with this...

Using a single reduction I can't quite get down to the 15:1 overall of the existing double reduction belt system. Best I can acheive is 11:1 using standard karting sprockets (9t pinion and 99t rear sprocket).

For the moment I'll leave it as it is, which at 24v will do 6mph- enough for plodding round the garden. However, I have just ordered a 36v controller from here: http://cgi.ebay.co.uk/ws/eBayISAPI.dll? ... 0408213050
Just like my Cinquecento I'll over-voltage the motor, to get a bit more ooomph.

It will initially run on Lead Acids, but hopefully I'll change to LiPos in the future.


More updates as and when (if you're interested!)

Pretty good. Looks a nice and simple setup like that.

Have you run it yet or are you going to fit the 36v controller first?

What batteries are you using?

Ran it last week, just plugged in a 12v battery direct to the motor (made it slow walking pace)- the girls loved it.

Blew up first controller - but now installed a new one.
Up and running at 36v, and its pretty quick, it wheel-spins on grass really easily.
