Converting a Car Alternator into a Go Kart Motor

PART 2:
• Building an Alternator...
PART 3:
• Building an Alternator...
In this video I will be showing you how I converted this old alternator into a motor for my electric go kart. The only reason I chose this alternator is because it only costed me $20 and it was still in fairly good condition (any 3-phase alternator should work!). I I ended up wiring this motor in a delta configuration. Originally I was planning on comparing the motor when wired in a WYE configuration vs the motor wired in a delta configuration but I will need a more powerful battery pack before I can do so.

This reminds me of the early days of gas powered cars where my Dad would tell me about going to the junk yard and taking scrap cars to create stock cars, race them and improve them which later led to muscle cars and more innovation. It’s like we’re seeing it again only with EVs.

[@migascustomsounds3054]

My dad was a mechanic in Mexico. I saw him did so many engines n shit in our garage. Good times.he had a super B moppar and I dindt knew wat it was.

[@AndyKPOV]

My father did this. Had a 7 second n/a bug in the 60-70's. He told me all the crazy stories. Chainsaw boats, go karts. Building cars for all kinds of thing from drag racing to demo derby. Wish it was that easy now days. I felt awesome when I turn a vertical shaft motor to a horizontal shaft. Showed my dad and he was like yeah that's the stuff we did. It was a better time back then. As a mechanic and auto body tech I'd prefer the 50's

I only considered disliking because he was sending Sparks from his Dremel right into the front alternator bearing, that alternator could turn into a big hunk of scrap metal very quickly if any of those Sparks make it past the seal on the bearings. I didn't dislike the video but I know several people who would for this reason and I wouldn't fault them for doing so.

[@gunner678]

Well actually continued usage of that construction as it is, would result in the catastrophic failure of the batteries, which would catch fire or even explode. Not pleasant. I know what you mean, but some negatives are probably down to that. It's a dangerous design.

[@mikeofallon]

Good video! In 1957 I had a home-made gas go kart & our Dad built a really simple generator driven go kart with my younger brother. No mods needed on the generator. Three 2x4s made the "frame" & 2 axels - steering with feet. Dad made a 3rd battery post out of solder in the middle of a 12v battery. (Batteries then had visible straps connecting the cells, covered by a tar substance). So you could run on 6 volts (about 5 or 6 blocks) at good speed. Then switch cables to the other 6 volts for the trip home. I'd run on all 12 volts & it was almost too fast on that little kart w/ skinny solid rubber wheels!

I did essentially the same thing when I was in grade school in the 1960's, using a mini bike, gears and chain from an old Honda motorcycle, an alternator from a 1950's model Ford (I'm not sure what specific model or year) and a "Juice Box" car battery, and it worked. However, doing this in the 1960's, using 1950's parts, it was anything but efficient. It would take all day to charge the battery, but 10 minutes to use it up. _But I sure enjoyed those 10 minutes..._ :)

[@CNCmachiningisfun]

*NICE!!!!* I made an EBike with a 100 Amp alternator last year. It tears along at 18KPH on a 14V battery, and uses 15WH per KM. Watt's cool is that it is soooooo quiet, it is recharged by solar panels - and it is such a pleasure to ride :) . Keep up the good work bro.

[@AndrewBrowner]

15Watt hours? or 15 amp hours? big difference on a 12/14volt system

[@CNCmachiningisfun]

Howdee Andrew, 1 Amp hour at 14.5V - is 'watt' this bike consumes when it is traveling on a level path at 18KPH. It travels 4KM per 4AH battery, if I run them flat, but that's not such a good idea with these LiPo cells. I could make it go faster, with a higher DC supply voltage, but there comes a tradeoff between speed and range, so I have opted to settle for this rather sedate 18KPH speed :) .

[@donaldthrill5794]

Braking?

[@CNCmachiningisfun]

Braking is partly done by the alternator, but mostly by the bike's existing brakes.

[@CNCmachiningisfun]

+Perkins_RC76 If you can walk at 7 mph, I would like to see that. Maybe make a video of it? Maybe become an Olympic race walker? The true walking speed is closer to 3 MPH, so my 12 MPH bike is a LOT faster than mere walking speed :) .

ELECTRIC DRIFT TRIKE!!!! I'm super excited to see your next build. I have 3 electric drift trikes each with different drive trains.

Third has a split axle and two 1,000 watt motors powering the rear wheels independently. My favorite part is I use Dewalt cordless tool batteries to power all of my electric trikes and e-bikes. I typically get a mile per amp hour, never over-discharged, and it is easy to swap out fresh batteries. Keep up the cool videos.

[@CriticoolHit]

When joining wire ends untwist both ends and then slide one end into the other and twist them together. Essentially braiding the two ends together. Then apply solder and allow it to wick the entire way. Solder is not glue and using it to "adhere" one wire to the other creates a brittle joint that will come loose with vibration and time. Cool project though.

[@wellardbr]

"and then slide one into the other" - I know (I sense) you mean well, but this particular passage would need either more words or hopefully a YT video showing the technique. Thanks though.

[@nordic5490]

CriticoolHit lead solder should be fine. It thermal expansion and contraction that typically causes cracked solder joints, not mechanical vibration.

[@BTW...]

This guy is lucky he got the direction of each stator winding correct, because there is no way that 'start' and end' of each winding set can be determined by a simple continuity test. Too easy to have 2 in correct same direction and the 3rd in an opposing magnetic field orientation. This MATTERS, be it star or delta connected. So, solder if done correctly, might be good for a test, given the equipment to correctly determine this magnetic field directions isn't a garden variety instrument. BUT it's a pain... easier to use insulated screw tunnel connectors [the type electricians use in house wiring]. Once proved correct the far better way is to use a crimp connector, NOT dodgy solder as seen here, for the solid stator conductors to the flex cable. CRIMP connections if done correctly are always far better than solder in an automotive application prone to vibration like this. Frankly, the best way would be to take each stator winding to a 6 terminal block mounted on rear of the alternator rear housing and then bridge however you want [star or delta] and terminate the flex leads there.

[@BrunoPOWEEER]

Yeahh awesome video explaining all important details about re-wiring the motor windings, I like that you also mentioned the wye and delta configuration, it does make difference depending on the application. SUBSCRIBED to your channel mate, if there are any questions about making 18650 packs just drop me a message. *you'll need a good 5 or 6 cells in parallel minimum to deliver that current. A very common mistake is assuming is designing the pack around the "rated continuous current per cell" claimed by the 18650 manufacturers, if you get a "10A cell" and discharge at 10A continuous it will get EXTREMELY HOT, damage/cook random cells inside your pack. Your controller will likely handle 14s or 52v nominal, you'll get a better top speed and a lot more POWAAAAAAAHHH

[@BrunoPOWEEER]

sieve5 hahaaa thaaaaanks mate!!! Yes it's feasible converting a road bike, it's nice cause it's so light so it accelerates faster but I ALWAYS recommend people to convert MTB and use as a commuter. The reason is you're actually averaging much faster speeds and too speed too so you really need suspension and a fatter tyre. Potholes at 50kmh or faster on a skinny road bike you're lucky if you don't get pinch flat or hurt your wrist. Fat bike is AWESOME super fun but a bit overkill.

Bullshit dude. Do you not know the purpose of a diode?? Ya, they only allow electricity to flow in ONE direction. That is the sole purpose of diodes.

[@lazyh-online4839]

@@JM-yx1lm which is why you hook up the input wires between the diodes and the stator, not on the outside of the diodes. The connection on the outside of the diodes is what would lead to the rotor, and this output from the diodes leading to the input of the rotor NEEDS to be dc, which is why the diodes are actually beneficial.

Your battery terminal most likely melted because the screw/bolt was not sufficiently tight. This causes the joint to have a high resistance. The power lost in the high resistance joint (R * I^2) will cause heating in the joint. At higher currents a loose joint can get hot enough to catch fire. If you can rotate the lug/wire on the bolt using just your fingers, it is too loose.

[@bbstacker70]

I bet he is smart enough to know that. I'm for the high discharge rate.

if you say so... but uh.. an alternater isn't an electric motor considering it was made for the sole purpose of GENERATING electricity. a proper dc motor would be much much better, with a lot more torque.

Harley Me turns out that theese alternators are quite efficient even when used as motors.
