I built this electric go kart over the course of a few years.  I got the frame on Craigslist, and spent a long time restoring it.  The original frame came with a roll cage, but I removed it because it was a little to small for me.Then I bought the majority of the other components from scooter and Go Kart supply stores.  The motor is 36v and 1000w.  The controller is meant for an electric scooter, but I controlled it using a hall-effect pedal I found, instead of a wrist controlled throttle.  The seat is a tractor seat I bought from a friend.  I custom-made a box with a voltmeter to show battery charge, a key switch for ignition, fuse, and the charging outlet.  The batteries are 12v, 14ah sealed lead acid, and are wired in series.  I built the wheel assembly for the drive wheel myself.  All the wheels and tires are go kart wheels I bought on Ebay, and as of now are my main problem, as the bearing are low quality and keep wearing out.  In terms of performance, it has a top speed of about 25 miles per hour, can complete a U-Turn in a neighborhood street, and can brake from top speed in about 20 feet.  Please feel free to ask me any questions about this project!

 

<p>you should include instrucutions on how to build it</p>
<p>Did you use any battery with any go kart? cause ive built mine and wondering if i buy it or make it, im going to the side with buying the battery, would i just use any battery?</p>

All I want to know is what ccomponents I to make a electric go kart?. Just want to make sure I have everything.
<p>Hi. I am building something similar. I would like to find out which chain and sprocket sizes you used. Or what is the approximate gear ratio? Did you need to give the kart a push before driving the motor? </p><p>Thanks very much!</p>

<p>Hi, this is awesome! What did this cost approximately?</p>
<p>sorry it is 150 kg</p>
<p>hiii i want give power to the battery by using fuel cell plz give me the capacity of battery and motor to move 15 kg go kart...</p>
Hello, im going to make a Gokart and i have big electromotor it works on 24v,2,5A, 3000rpm but only problem is that the power is only 25w, is there any way to increase power of that motor, i think it can be more powerful because its really big motor but i dont know why it has low power
<p>The wattage is </p><p>volt X amp= watt so your motor should be 24X2.5 = 60 watt not 25 watt</p><p>there should be two coils inside the motor one is the rotor armature and the other is the stator armature which stays still only the rotor moves, you will have to change the stator with high power neodinium big magnets it will change the entirew configuration of the motor and thus will increase the wattage. you can also do a speed reduction by gears , 3000 to 300 then the wattege will increase to 10 times and will be 250</p>
<p>Hi - I have a 48v 20ah lipo lithium battery can you tell me a strong motor i can run with this battery for my go kart? something not too expensive </p>
<p>1000 watt 48 volt 4000 rpm, there should be a speed reduction chain sprocket and you will get a very powerful motor for a small kart. for other helps including li-ion battery contact me at parasarb121@gmail.com, i will be obliged to help yo with anuthing.</p>
Theoretically you could run any 48v battery off of it. 20ah won't give you much run time htough.
<p><a href="http://www.instructables.com/member/shakti%20swarup" rel="nofollow">shakti swarup</a> 12 volt of 20 amp hr battery (4 that makes it 48 volt 20 amp hr battery pack. now voltage of the motor multiplied X amp of the motor = wattage of the motor now suppose you have a motor with 1000 watt then</p><p>voltage 48</p><p>watt 1000</p><p>amp =?</p><p>amp of the motor is= watt / voltage</p><p>which will be</p><p>amp= 1000/ 48</p><p> =20.83333</p><p>so the ampere the motor uses is 20.888</p><p>hence your battery is 48 volt 20 amp hr so it can give 20 amps in one hr hence theoriticaly your car wiill go a little less then 1 hr, but in practically there are some energy losses which concludes that it may run 45 min.</p><p>You have to know the wattege or amp of the motor. for battery heigher power and other help you can contact me at parasarb121@gmail.com.</p>
We r working for a projet,where we use 12v 20 Ah of 4 lead acid batteries in series and a 3000 rpm of bldc motor..we are little bit cnfuse as it is our first attempt ..that is this specification really work,how ?and how much time we can drive our kart ?? How we know about the discharging of battery..u made a kart...how much time reaaly a battety can drive the kart..could u explane me plzz
What is the frame made of<br>
<p>what is the Max riders weight ?</p>
I'm hoping to build a go kart like this and I'm a rookie in this area plz any knowledge that you think could help me here would be useful
<p>I want to make a hybrid go kart which I can power with an average performing fuel engine in the rear axle and use a electric motor to drive the front axle.</p><p>I would like to have your guidance an help in this.</p>
<p>how much did it cost and how can you make it faster and how can you make the battery last longer</p>
The cost was around $400-$500. You could make it faster by adding another motor or making the current one more powerful. And the battery could last longer if it had a larger capacity of the motor was smaller.
<p>Nice Kart! From my (extremely limited) knowledge of Hall-Effect pedals, you need a scooter controller as well... Any ideas how you'd set that up? (I'm guessing so since you've built one)</p>
<p>Hello !</p><p>Can u tell me about power, mass, acceleration, speed of a kart which u had made ?</p>
<p>what material could be used for building up the base frame?? </p>
<p>Steel would probably be the strongest and easiest to weld. You could use aluminum to keep the weight low, but that would come with some construction challenges. I've seen some wood gokarts, which seem like the easiest to contruct, but the weakest as well.</p>
<p>I want to make a electric car for mechanical project I need a dc motor less than equal to 3000 w max rpm 3600 max torque 12.8 nm at 2400 rpm power consumption max 48 volt can u recomend me some motor name or link which would suit best for me....thanx in advance...</p>
<p>If it's a full size electric car, then 3kW will be way to small for any normal driving. I got my gokart motor from a scooter supply shop, so you could check those sorts of websites. I can't really help with any more specific specifications, sorry.</p>
<p>How do the bike forks work?</p>
<p>They prop up the seat a little to allow the forks cushion bumps.</p>
<p>i know this question is a lil silly to ask but can we use a 5/6 volt motor having 10000 rpm and a potentiometer to run a go kart?</p>
<p>Do you know the power (wattage) of the motor? It would take some incredibly serious engineering to get useful work for a go-kart out of a motor with 10,000 rpm. I would probably look for a new motor. Good luck on your project!</p>
<p>how long do the batteries last?</p>
<p>Around 30 minutes of driving time in my experience.</p>
<p>That's Cool!</p>
Hey...i m too thinking of working on dis project...i had a doubt... cud v use a small generator to charge d batteries while d wheels rotate d axle of generator...it wud make it self charging!!??
<p>The First Law of Thermodynamics tells us that it is impossible for a contraption like that to work indefinitely, no matter how helpful it would be. There is always going to be some loss of energy in the system. However, you can use something similar that extends the range of the electric vehicle (not indefinitely) by recharging the batteries with the motor when the brakes are applied. Some of the energy of the cart goes back into the batteries, allowing the vehicle to operate longer. This device is called a regenerative brake, and is used by many major electric vehicle designers. The <a href="http://en.wikipedia.org/wiki/Regenerative_brake" rel="nofollow">Wikipedia article</a> will give you a good idea of its uses and limitations. Electric vehicle designs can be very complex but simple designs can be successful and useful to learn from. Please reply with any questions you may have!</p>
Thnxx fr such nice explanation and a quick reply...can you please suggest me the whole wiring including the battery controller motor. And pls tell me what gear ratio to use?? What type and rating of voltage/ power battery and motor to use? (keeping it in mind dat i cud at least drive for 50 minutes at avg 25 km/hr.. fyi m a bit heavy)
<p>I've answered most of these questions in other comments, but keep in mind range is related to the capacity of your batteries as well as the power draw of the motor. Wiring will depend on the controller you are using.</p>
Also can you please suggest wether i should put on some cooling fan for the heating motor? Thnx in advance!!
<p>Some motors have fans built in. If the motor you are using is getting to hot, then you should confirm that you are supplying the correct current to the motor, and if you are, then try using a cooling system.</p>
<p>bro,can you give me the full specifications of motor,batteries and the stearing mechanism of this go kart i want to build the same thing....and also how to apply the motor contoler and gear to the motor......</p>
<p>Motor: 36v, 1,000 watts</p><p>Batteries: 3x 12v, 48ah wired in series</p><p>The steering is just the standard tie-rod mechanism that is common with go karts. The wiring for the controller depends on the controller itself, but most should have a diagram. The wheel is driven by the motor with a scooter chain. Good luck on your project, and please let me know if you any more questions.</p>
<p>simply amazing :)</p><p>as i gone through all mentions about this project, i would like to know how to determine the basic idea to select-</p><p>battery type</p><p>motor type</p><p>what if i want to build a kart weighs (frame=25kg + avg driver=60 kg) near about 100 kg. and desired speed = 35-40 km/ph .so,what will be the ideal categories and specifications of motor and battery (data) to select in order to get DESIRED WORK MODEL </p>
What kind of frame do you have? Is it a racing kart, homemade, wood, or some other thing?
<p>This may sound like a complete rookie question but do you know if you can use one controller for two motors because i am aiming to give mine two 1000w motor for higher top speed as i live in a very hilly area</p>
<p>Not a bad question at all! Dual motors setups are a great way to increase power, but they have a few caveats. Regardless of the number of controllers you use, you should make sure that you use a live axle. A live axle spins with the wheels, ensuring that each rotation of a wheel is matched with an equal rotation of the other wheel. If you don't have a live axle, you will run into problems with two wheels running at different speeds. It's manageable in some cases, but a live axle is always better. But in terms of controllers, you should be able to get away with one controller, as long as you make sure that it is rated for the power that both motors will draw, and you wire it correctly. Feel free to ask for any clarification. I'm glad to help.</p>
<p>Hi, was just wondering about your electronics setup, where did you get the motor controller from and what was the circuit like, for example batteries wired to controller wired to motor? I'm building a small electric kart with some friends and we have the motor, batteries and wire but aren't sure how to connect it. Thanks in advance</p>
