Default Want to start an electric go kart project

hello everybody im new to the site as well as making go karts or anything motorized haha but i really want to learn about making things of that nature. i want to build a frame out of wood primarily due to the fact that i A. cant weld B. its cheaper and C. it seems easier to work with haha. Im not sure what kind of motors or batter to use. i was thinking of just using some car batteries i can find but any information on what to use as far as motors, batteries, and controllers would be very helpful. im just trying to make a small go kart for one 200 pound adult. im not looking for something super fast or crazy awesome just something that i can cruise around in haha SO PLEASE ANY INFORMATION WOULD BE VERY HELPFUL...OH AND DONT BE A DICK EITHER

wood is not a good idea
it is not a strong enough material paticularly for any steering components, drive train and mounts or engine mounts

on a kart that pretty sumes up the whole structure

some people have used it but for hill karts or for the body of antique karts

welding isnt that hard to learn and not very expensive to get started in these days

You can pick up frames not to expensive, Used ones that just need some dedicated time and work are Great. Ask around the family and friends you would be surprised at what people have laying around that that don't want nor need. Metal is quite a bit heavier, you probably know that, I am not very familiar with electric motors but make sure your motor will be strong enough if your 200 pounds and the metal frame is a good 50 to 100 pounds "correct me if i'm wrong Fowler"

Think about gear ratio to if you want to cruise at 10 or 15 or if you want 30 MPH you will need the right gearing for a decent take off and speed. Do you know the Horse Power of the motor? Like i said im not an expert with electric motors or anything but could you make like an electric motor off of an air compressor work they run 2-6.5 HP engines and higher.

A Throttle would you need something to adjust the current? I would consider reading and studying electric scooters and how they work for a good while and just apply the knowledge in bigger form. Notice details on size of the motors, RPM, how the current works, and wiring. I would ask a friend or family member that knows about electricity and currents.

P.S. If you have kids or young family members its a great way to spend time and get to know them. Im 14 and i have worked a lot on combustion engines with my grandfather and its a great way to spend time with them before it to late:/. I have great respect for him Its just something i consider on projects.

OH and for batteries i would go with quad or dirt bike there more compact and less weight.

im thinking of using his motor:
http://www.scootercatalog.com/xtreme...motor-48v.html

and 4 of these batteries:
http://www.ebay.com/itm/12V-20Ah-APC...item41612dc0c5

im still gonna just try wood and if it fails then ill use a metal frame the next time im not trying to build some super awesome go kart just something to cruise down the street to walmart in you know what i mean? haha it doesnt have to be super fast i just want to see if i can get the basics down of actually making this thing and pretty much i just want to learn something new. i already have an idea of what i want to do so im gonna try and give it a shot i just want to know more about the electrical aspects. i dont mean any disrespect and im not trying to sound like an arrogant prick but if i think i can make something work i want to atleast try and if im wrong ill go with what someone else says but my primary goal is like i said just the electrical parts =) i think the 48v motor i found would be pretty good and i like those batteries. let me know what you think



heres the video i saw that made me want to choose this motor and battery:

I think people knock the use of wood too often. Yes, I agree that it shouldn't be used on any kart that is going to go faster than about 10mph, but if it is only used on flat surfaces, and at low speeds, and is constructed well, I am sure that you can get away with it.

The first thing I see that is a problem on your engine is that your starter cord is hanging out the recoild housing. That probably means that the spring has unwound in the recoil, or you have to replace it for some reason.

Check for spark by taking the plug out, putting the plug lead back on, and holding it agaist something metal crank the engine (oh...i just remembered you cant pull the starter. You might have to get that fixed first). When you are able to do this, check if you can see the plug spark at all when cranking the engine

If there is no spark, it could be a bad coil, or if it is a point engine, the points could be dirty.

Have a look at these sites:

I was going to suggest that you just find a used kart. It would be cheaper than trying to build one.

Also, that 350 watt electric motor is way too small. If this is for a child 500 watts should do. For an adult, you will want a least 1000 watts, if not more. Two independent 750w motors would work nicely.

The batteries you have picked should be fine. I would suggest using a Kelly controller, as they are higher quality than the little scooter controllers.

Go here and scroll to the bottom. There are videos of the kart with a 24v, 500 w motor running on 36 v.

but see thats the whole point of me doing this...to acctually build one. im not looking for the easy way out and just buy ****. i want to do everything myself and learn how to build **** on my own. this project is going to be the start of many self-reliant projects. i got the idea from watching season 1 of The colony. ive always been into apocalypse theories and self-reliance and **** like that but ive never acctually BUILT anything for myself so what better time to start then now right? haha so yes it might be cheaper to buy one but thats not what im looking for. money is not an issue for me ill save up if i have to or scavange **** i dont care whats really important to ME is that i build it myself.

as far as the motor im going to use a 48 volt 500 watt electric motor and i think itll work fine because thats exactly what this guy used in his scooter in this video . The wooden/electric kart im going to do is going to be for my 7 year old step son so im pretty sure thatll be fine. for myself i have a 6.5 hp gas engine on a metal go kart frame but thats a different project

I'm not sure I would use the word "guru". Sure enough there's some good ideas there, but overall I find there's more flash than form there.

Either way, a "can do" attitude is always a good one. Just think things through, and build with safety and structure in the forefront- not how fast can I nail these 2x4's together and get it moving. Sure- you CAN build a wooden frame- and it has the potential to be pretty sound. Trouble is, most people wouldn't be capable of building a structurally sound wooden frame- not under 500lbs, anyway. Pound for pound, a welded steel tube frame kart will come out ahead in strength and durability much more often than not.

Sorry, I assumed that the kart was going to be used off-road which is going to need a little more power than an on-road kart or scooter.

Also, another thing to consider is that you can bolt together metal pieces instead of welding them. You'll just need a few braces to keep everything square. Or you could use metal brackets to reinforce your wood frame. I think a wood frame kart would be kind of cool, but I like working with metal, so that's what I tend to lean towards.

Back to my comment about buying a used frame. There are a lot of pieces that will come with a used frame that you could possibly use on your own frame.

Seat
Steering wheel
Steering shaft
Tie-rod
Front knuckles
tires
wheels
brake system
Rear axle

You can strip most of those pieces off of a frame to put on your wood frame. Of course, if your goal is to learn how to make all of those pieces, then buying them won't do you any good. I understand the desire for that kind of project.

Just a word of caution. I didn't hear him say that it was a 48V, 500W motor. He said the scooter was running at 48V, and the motor was rated for 500W.

It could be a 24V, 500W motor that he's pushing at 48V, which will almost double the power output.

hello everyone, I am also building my first Go Kart and doing it electric but wondering how would you connect the throttle pedal to work with electrical motor/controller as it's electrical? I am working on using this kit ---> 900w Motor & Controller.

Sorry for asking this question here, appreciate the help in advance.

Default electric throttle

I used a foot plate hall effect throttle from TNC scooters. Instead of mounting it as the real throttle, I drilled a hole in it and ran the existing throttle cable through it. This converted the mechanical force from the original throttle to the electric throttle. I did not want to mount the electric throttle up front since it wouldn't match. Here is a pic:


for detailed info on my electric go kart project, visit my http://electricgokart36v.blogspot.com/blog. I have links to websites so you can buy components.
Good luck with your project,
Alan
