I have found this exact kart model abandoned near a dumpster . This video is all that i needed to turn that old piece of garbage into an awesome ride. Thanks.
Actually your totally right here. I have a chain guard off of a kids bike that is perfect for the job but not put it on as my son has no interest in the moving parts. I'm so bad as this should not be a reason to not bother doing it. Thank you for mentioning it though as I need a kick up the back side to get on and do it.
Sorry to be offtopic but does someone know a tool to log back into an instagram account..? I was dumb forgot my account password. I would appreciate any assistance you can give me
@Israel Wesley thanks for your reply. I found the site thru google and Im waiting for the hacking stuff now. I see it takes a while so I will get back to you later when my account password hopefully is recovered.
Yes, most alternators seem to be around 3 ohms for the rotor coil. Converting it to permanent magnet is the only way to get around it. You can use less voltage, but it gives you more RPM and less torque.
Thank you for confirming what I feared to be the case. Also thanks for giving a more scientific explanation on why the alternator conversation isn't the most efficient motor for this kind of application. I would say though that even given its drawbacks of the extra power drain due to the rotor coil needing to be energised to make the motor/alternator turn, I'm finding the range with the home made battery pack is really good. Approximately 6 miles with pulling a trailer. There is also the fact that the alternator was free to begin with so factor in maybe £100 for a motor of comparable suitability I think we are still pretty good with this build costs verses efficiency.
@@SlightlyModifiedUk 6 miles, wow! Since it doesn't appear that you need much toque for your uses, maybe try dialing the rotor voltage back further and further until you run out of needed torque. If you cut the voltage in half, you QUARTERED the power wasted on the rotor. :)
@@foxxyytofficial very good question. I paid about £30 for all the electronics. This consisted of the speed controller, a step down buck converter (36v to 12v) and a remote relay to allow me to kill the power when my son looked like he was going to hit something lol. The last item was a very good purchase I can tell you!
An idea may me to have a relay to energise the rotor winding when the throttle is pressed. You can get relays for about 10 euro. Just be aware as the motor is put under pressure, that 4 amps will increase. Good video, thanks
Thanks for the great advice Aaron! Great minds, I was thinking of something much the same. I probably need to make a new pedal which will accept a small limit switch and then as you say pass it through a relay. I would be interested to find out myself how much battery it would save.
Nice video. I was hoping there was something simple to do to make an alternator run like a motor, like something internal. I will have to watch the video again, because it sounds like I would need to buy some kind of electronic piece to get the alternator to even run like a motor. This was the first video I watched on the subject, but it seems to be a popular subject right now. Thank you.
Thanks for the message. Apologies for not going deeper into the inner working of how to convert an alternator into a motor. There were 2 reasons firstly I had already converted it before I even conceived of the idea of making a you tube channel and secondly there are quite a lot of other people who have shown how to do the conversion and they most certainly do a better job than me. But What I would say is to do the conversion is very easy. You actually simplify the alternator by taking out the charge controller, you then are left with 3 wires (phase wires) and the 2 wires for the brushes. You do need a speed controller to power the motor but these are so cheap now (start at about £20 on ebay) that they don't add much to the overhead of building a project. Even a simply 2 wire motor would need speed regulation so no extra expense. Hope this helps and thanks again for watching.
You are way ahead of me sir! I have a mk4 golf alternator sat here on the bench and I got a cheap VESC off of ebay, just not time yet to play. did you choose Y or Delta config? How hot did the alternator get? Also did you try less than 12V for the rotor windings? I imagine it runs slower but uses less power / battery drain, and then you can compensate with your pot to off set that?
Big thank you for the message. The golf alternator is a great choice. I used an alternator given to me from a Ford fiesta. It's smaller than the VW one but meant it just fitted under the seat of the cart without modification. I really wish I had taken video of me modifying the alternator but at the time (several months ago) I had not even thought of the idea of a UA-cam channel. Anyhow, thinking back I think the alternator was wired in a Delta configuration. Last weekend was probably the biggest test of the build yet. We went on a walk through a forest near to us and my son had his trailer on the go kart loaded up with wood and toys. It was about 3 miles and pretty rough terrain with hills. The alternator never went above slightly warm. There is a sweet spot for the field windings voltage. In my case (and I think this will be different for different alternators and different phase voltages) it was between 6 and 8 volts, too high and the motor looses power, same for the lower end of the scale. As mentioned in the video, even not moving the field windings use about 4 amps which does mean the conversion isn't the most efficient option available. Overall the battery will last for at least 5 miles (maybe more if I were prepared to push the go kart home when it died on me) but seeing my son being powered along on something that I converted from a free gift gives me a feeling of immense satisfaction. I really hope you get the time to complete your build. Look forward to seeing how it goes (I will be subscribing!).
36v 1000w controller would have been a better choice.... £40 Ebay I'm thinking about converting my dad's old mobility scooter... I don't understand why more people haven't done mobility scooters because they are amazing if done right 👍
Yes your right about the controller but at the time I couldn't get hold of a bigger one that would suit. I also wanted one that had a reverse but failed on that front as well. But that said the controller I used in the video is still going strong and as a first go kart for my son it was a perfect choice as it was slow enough to not cause too much injury when he crashed (and he did crash a lot). When I turn it up to max now that he is older it goes quite fast and I have to run at full speed to keep up with him. I'm in the process of building a second go kart for my son now which I'm building completely from scratch. The original one (this one) will be going to my younger son. Hoping to publish the video(s) of that soon so watch this space!
Thanks for the comment. I connected the potentiometer between the speed controller and the output from the pedal (green wire I believe). This worked really well for me. Also the speed controller has 3 speed settings which gives you even more control.
Thanks for the comment! The brake is a lever on the right hand side, pretty crude as it just rubs against the rear wheels to slow the cart down. I connected up a micro switch so when the handle is lifter it kills power to the motor. Now I just need to convince my son to use the brake as he has no fear whatsoever.
Very nice. I have the same type of pedal car, it’s just quite a bit older ( made in west Germany it says) with much smaller tires, I’ve been thinking about putting an electric motor on it for my kid. Very wise putting that diamond plate on this particular car otherwise it is very dangerous without the floor installed because my kid can very easily run his feet over. I love the way you reinstalled the rear axle locker, that’s 👏 awesome. I may have to steal that idea from you
Thank you so much for the awesome comment. Please feel free to take the idea off locking the rear axle it's been really useful for going over muddy fields and towing his trailer around. I really hope you get to convert your pedal car for your son or daughter. Good luck with it!
Thanks for the comment! I can confirm that after about an hour of use the alternator/motor is only slightly warm. It really is the perfect size for the kart even when towing a trailer behind. I am hoping to do a follow up video very soon on how the go kart is coping now that it has been in use for over 9 or 10 months. Stay tuned!
Wow that is a very cool industry to be in! Do you have any content you can share? If you mean the url for how to convert the alternator then check out this: ua-cam.com/video/IKqy3rRWJQE/v-deo.html You can get an alternator practically for free at any car breakers.

Oh wow great find! Send me some pics when you finish it.
Great job. I'll have to try this for my grandson. He'll need a chain guard because of his strange fascination with gears and wheels. Again, nice work!

Quelle est la puissance de la batterie que vous utilisez??
Merci pour le gentil commentaire. La batterie dure longtemps, généralement 8 km.
I build the Same from one PEG.
hay man rally nice..
Y am in process now..Wher are you connect power up and down(potenciometar). On baterry out or? Have big problem with speed
Thanks for the comment. I connected the potentiometer between the speed controller and the output from the pedal (green wire I believe). This worked really well for me. Also the speed controller has 3 speed settings which gives you even more control.
Thanks a lot for comm..Y know now..
best for you man..
Nice job. No brakes ???... looks like there are not too many hills there though 😁

Класс! Молодец , аккуратно сделано!
Большое спасибо!
Cool! I want to use an alternator as a motor too. but I would like to ask you a question. How hot is an alter-motor after driving Go Kart?
Thanks for the comment! I can confirm that after about an hour of use the alternator/motor is only slightly warm. It really is the perfect size for the kart even when towing a trailer behind. I am hoping to do a follow up video very soon on how the go kart is coping now that it has been in use for over 9 or 10 months. Stay tuned!
what motor are you using ?
I'm using an alternator off of a Ford Fiesta which I converted to work as a motor. It's perfect for the job and it was free too.
Can I have the URL link ? Greetings from Singapore. I am working in UAV industry for 5 years. Always like hands on related stuffs
Wow that is a very cool industry to be in! Do you have any content you can share? If you mean the url for how to convert the alternator then check out this: ua-cam.com/video/IKqy3rRWJQE/v-deo.html You can get an alternator practically for free at any car breakers.

Does the alternator keep the battery charged 🤔
I wish it did. Regen breaking would be the way to go but the speed controllers in my price bracket don't have this feature unfortunately.
