I want to convert my gas gokart to electric. Fully loaded with me and the dogs, it weighs less than 500 lbs and does not need to go faster than 15 mph. We drive on level ground and only need to go around 3 miles per day at mostly walking speeds.
The rear axel has a 9" sprocket with what appears to be #40 chain and I would like to keep that sprocket and chain if possible. I see that the motors like the the MY1020 have 8mm sprockets. Is it possible to change the motor's sprocket to fit #40 chain, or should I replace the axel sprocket to accept the 8mm chain?
How many volts and how many watts do I need? Is that 48 volt 1000 watt motor a logical choice?
My lights are LED and the siren and horn don't get used much or draw much power. For now, I'll just use a small 12 volt battery I already have.
ElectricScooterParts.com can make the 8mm 96 tooth sprocket for me, and they have an axle hub with keyway that fits my axle. I want to reuse my original axle hub though so I plan on having them make the sprocket with a 1-15/32 inch center bore, which should just fit over the hub retainer on the flat side of my old sprocket. I'll drill holes in the new sprocket to match the old and bolt them together. The new sprocket will be 11/2 inches bigger in diameter. D
Does this sound like a good plan?
I got my new sprocket from ElectricScooterParts.com. The center bore fits over my old hub perfectly. I'll bolt them together with stainless hardware. My motor kit from you should be here any day.
It will take me a few days to put everything together and I should be able to see what length of chain I need.
Your stuff should be here tomorrow.
Do you have any advice and what type of hardware I should use to bolt the two sprockets together?
My stuff came yesterday and it all looks great. Nice and neat and well packed. I have plenty to do to get the kart ready to hold this stuff, but I'll get that done over the weekend. After I get the axel sprocket and the motor mounted and lined up, I will measure for the 8mm chain and order that. I do want to make sure you will be there to help me connect all of this up correctly. You got my back on this...right?
I'm ready to order my chain. I have the motor mounted on a piece of plywood and the plywood slides about an inch front or back on the steel mounting plate grooves. When I slide the motor and it's wood mount forward and wrap a cloth tape measure around the sprockets like the chain would go, I get 39.5 inches.
This site's chain length calculator tells me I need a length of 38.67 inches or 122.76 links. How much chain do you suggest I order?
Thanks. I'll order 126 links.
I have my piece of 1/2 " plywood all fiber glassed with epoxy resin and mounting bolts all worked out. The chain will be here on Monday,and then I should be ready to roll. I temporarily connected things up and I have a female connector labeled Motor 3 with a black and a red wire coming off of the controller. What plugs into that connector?
We also have a connector labeled reverse with a blue and a white wire coming out of the silver junction box and nothing to plug into that connector.
