very true. that is why I like UA-cam because I can find people who know / appreciate both aspects.

there are automotive alternator magnet kits for diy wind power generators .the last time I tested one for a customer was about 15 years ago so not sure if they are still available .that's the time when neodymium magnets were the hot thing to make projects, the ones I've seen came with a rotor cast from aluminum with magnets for 10 si gm alternators
Dude, I’m studying AET (Automation and electrical technologies) and this is right up my alley. You did a fantastic job explaining everything. It was a learning experience for me as well. My question is how did you convert DC into 3-phase AC?
Absolutely impressed with your skills and determination, I would definitely continue improving and expanding the product base to a standard baseline and market it locally. Cheers and don’t give up.
Your logical reasoning had you thinking it was something mechanical and it was…the positioning of the hall effect sensors. Nice prediction. The answer finally hit you after staring at it a long while, I imagine. Congratulations, you should be very proud; especially after that company sent such a discouraging letter
Great project, I’m impressed with your tenacity with the Hall effect sensors. They are not easy to understand at first and I thought you did a good job of describing their function. Really good job and video overall👏 Thanks.
@@austiwawa you definitely come through as genuine and guided by your own internal compass and inner light. Stay you. Stay true and i see success and happiness as two of your life’s major constants.
@@austiwawa I'll post this again here in case it may not have came to your attention. Just curious what you think about this: The centrifugal clutch idea could easily have worked properly, by either putting lighter springs in it, increasing the mass of the flyweights, or a combination of both, or else by getting a bigger clutch if that one was too small. I was also thinking you could have added a micro switch to the throttle, triggered by the initial first couple of mm of motion, connected to a relay supplying field power to the electromagnets. This would have eliminated the issue of the motor constantly spinning at a low speed. Great final product though. Keep up the good work!
@@smallblockchevy1022 removing the clutch was better, because the sensorless controller couldn't spin the alternator as fast as the other controller and with hall sensors it was even better and cutting the 12V field is a bad idea for the controller
Love your enthusiasm an knowledge of motors/generators I build similar projects I'm just much older an hopefully I have experience but your a good influence on people your age to know mechanics Bill
Difficult to comprehend how anyone could "dislike" this great video, and puzzling that those who did would not take the time to explain why. Keep up the terrific work there!
Awesome job I made the comment about adding a smaller alternator to recharge your batteries and maybe double the time of the 30 minutes you have driving. I was wondering if you saw the UA-cam video where the kid in the third world country used a well-kept secret in using water to power his engine on a scooter. Is that really possible? It looked real.
I found that the best way to share my knowledge of electronics, was to play lead guitar in a rock & roll band, back in the 1980’s. We are so lucky that video was scarce. Now I study “the circle of fifths”. Cheers.
Converting the alternator was very impressive! But the most impressive part to me was that you are determined to find a solution and you did great job young man keep doing what you were doing with that same determination and you will go very far! GOD BLESS 🙏🙏🙏
THE BIKE SHOULD BE PUT BACK TO ITS ORIGINAL DESIGN AND LEFT THAT WAY. IT LOOKS LIKE SHIT WITH A STUPID MOTOR ON IT WHEN IT WAS NOT MANUFACTURED THAT WAY.
Thx/ Dankie. U give me an idea... With the trouble a week of so ago in Natal (ZA), it always good to have second engine on your motorbike. If or when u r strande on the road in an unsave place. The electric motor can get same kms away...(a slow speed is better than NO speed...)
Great Video and very well explained. I wanted to build a similar project but I need to know how much power it is drawing (Amps, Volts and Watts), so i can pick the right controller. Thank you
Absolute genius, super impressed, just be a bit careful on that old bike, parts like the forks are under more stress than normal , wouldn't want them snapping on you. Let me know if you go into production, stick me on the waiting list.Somebody get this chap some funding from the stock market and get them in to production, recycling old alternators as well!
We need more young people like you please continue and please Inspire other young people our future is in your hands. And I really do mean this our future is in y'all's hands God bless
If you ride at speeds higher than the bike is intended, reminder to check the axle bearings and grease. I made a minibike in the 60’s from a stingray bike and a 65ccClinton go cart racing motor. It would go 50 mph and after every run the bearing grease overheated and spun out of the bearing housing. It would not take long for the bearing balls to separate from the bearing. Caged ball bearings were the common type at that time.
OK, soooooo, I didn't like the Clutch. I put together a vert small lawn mower engine chain driven very small Mini Bike which started by dragging the back tire, jumping on... throttle pretty much took the place of the brake and to kill it just pull the brake. Worked great and My neighbor's kids loved it! Why not just turn the controller on and off? 42mph very good!
Good to see finally there appeared a skid lid... Maybe making your brakes compatible with extra speed/ mass- it seems there are no levers on the handlebars, indicating the bike doesnt indeed HAVE brakes. As a rider who has a intimate knowledge of road rash, this i believe isnt something to be swept aside, as you are rncouraging higher speeds to be attained with your ideas. Also, this could affect not only the rider of such a contraption, but the driver/ rider/ pedestrian/ child that you might seriously hurt in the process. Other than that, cool ideas..
Nice one mate, I have got up to 45mph on my mountain bike going down a hill and that felt sketchy as hell. I can understand you not wanting to go faster lol. Will be great when the battery technology gets better and you can have more range without huge expensive batteries.
Great work done!! It also gave me more insight into the hall effect sensors, which has given me problems before. Thanks so much and keep up the great work you're doing.
HECK YEAH!!! FINALLY! I waited for so long, and finally you installed the hall sensors on the alternator!!! My years waiting finally paid off!! The youtuber "Enrengineering" also installed hall sensors on his alternator go-kart
@@OverbuiltByHenry the only steps that i saw you stepping and remember from head were the top speed tests with modulation of tbe PWM brushed system, and the hall sensors on the middle of the stator (you put on the end of it)
@@austiwawa i am so happy to have you answering me Since the first alternator video i tried to help people in the comment, not just in your channel but in others too, like Enrengineering's channel
on the good side: you can weaken the magnetic field for more speed by varying the rotor current or make it stronger for more torque. free gearbox basically. however on the bad side you wear the brushes and its less efficient since you have to waste energy to keep the magnetic field active. you could also use it for regenerative braking by feeding back the energy in the rotor instead of applying 12v when hitting the brakes.
You're not going to wear the brushes by any noticeable level, considering alternators can potentially run hundreds of thousands of miles with no maintenance. It's a slip-ring not a commutator, so there's no slots to wear down the carbon
It would be interesting to drive the alternator with a VESC, and write a custom app for it to control the rotor field voltage. Since the VESC internally knows the ERPM, it could easily take that and apply it on top of a curve you define which determines the field voltage. Have the VESC output the setpoint to a DC-DC adjustable Buck regulator, and it be able to dynamically and automatically adjust for optimal torque and RPM.. I might have to play around with this.. heh. Another neat feature of something like this, is since the VESC directly can read the throttle input, it could also just disable the DC-DC regulator at 0 throttle. Thus eliminating the parasitic current draw at 0 RPM.
@@Hyratel, diesel trains have brushed motors driving the wheels that contact the rails. These brushes have to be changed out regularly. I was informed of this by a (now deceased engineer). There are several sets of them. If you have a brushed motor, plan on having to change them out, there is no free ride.
This is awesome!, I think your power problem lays on the "Y" configuration wiring...try wiring the motor in a Delta configuration, you'll get way more power use but double your torque!
Your efforts were worth it in the end. Very much enjoyed the video. I like the way you worked through your issues even though the manufacturer for the controller said it can't be done, good job.
This is such a cool idea! I'm getting parts to build a motorized scooter with 16 inch bike wheels, and this kinda gives me hope that I can still get it done under 1000$. Very cool work!
this contraption is quite sound, and can be doubled, inexpensively, considering the alternator(s) can heat up on longer trips.. on a scooter, you could easily carry two systems & use gel cell batteries, because they are very deeply charged.. you could, conceivably create a virtually non-stop cycle (or cart) with the use of panels, and precision bearings at shaft races.. good luck on your awsome scooter project..!!
@@edgarvalencia7523 Only if you could make it light enough. The weight killing the range is more of a problem than the power delivery method/feel with EV's
@@kylem7708 right on not experienced in the EVz but ya I fill like it could be tweeked for Les pull on the motor n more torque to the drive wheel good up hill climb but I only have tried on carts for a heavy guy but it is a hell of a build 👍🏼
Dear Alternator converter to Electric Motor technician. FredNZ thanks U from "the ends of the earth" down here in South Pacific.

Thank you for sharing your skill. Fred Hughes
Little tip about the rotor - if you reverse the polarity on it you reverse the direction of the motor. Also don't feed it direct with 12V, try feeding it via a 3W 12V bulb to reduce the current it takes and the subsequent heating effect in it. I've seen the results of bypassing a charge warning light on a diesel generator when the bulb blew, wasn't pretty! Using a 3W (or even a 5W) bulb will prolong the life of both the rotor and battery. Other than that, great video and yes, HE sensors are tricky to get your head around - i found it easiest to think of them simply as a switch which changes state as the magnetic field around them changes.
Does the bulb balance the current or something? For the motor, do you think these numbers could be reversed? /approximate? "An alternator typically takes about 1 HP (horse power) for every 25 amps of power generated. So, a 100 amp alternator will require about 4 HP at full output."
@@dizzydinonysius As pointed out above, the bulb restricts the current to the rotor to prevent it burning out. As an alternator is a wound component, the generally accepted efficiency is ~80% (there are more and less efficient variants) and a 100A alternator will output 100A @ 14V. Simple Ohms Law provides 14 x 100 = 1400W, divide that by the efficiency and it needs ~1750W to drive it which is ~2.3hp. If the alternator was a 24V type at 100A this figure would be doubled. However, reversing the figures isn't possible, the alternator in the thumbnail that heads your vid is 40A which would be ~560W@14V output. This means it's capable of being driven with anything up to 560W of electricity. As 1hp is ~750W, thaat would be roughly 2/3hp. Hope that helps!
I admire your dedication to making the most incredibly backasswards shit actually kinda sorta work. You sir, have 99% more patience and motivation than 99% of us...
Excellent work !!! Great knowledge and the ability to create and modify, passion that I have personally. I also built an e-bike from a kit using a three phase brushless motor.

Great idea, I would not have used a clutch on an electric motor. The way I would have fixed your problem is fixing a switch on the accelerator that would turn off the drive while at rest, I would gave let that little spin be the lowest speed you can ride as you accelerate.

I take joy in the expression of someone else's genius. I got a lot of joy out of this.
"WE ACT, AS GOOD FOLKS - FOR LOVE"
for you i would like to simply, say,
expressing in such very good ways
is always respectable
and it deserves..
it reminds me of my older works,
so, in the case of your say, today -

my quote, returns :
soliloquy from 2017, where 'katiger says'
"as our joys in this world
shall include your achievements.."
- warrior poet
in the days of past and since then, as said,
they have remained equally, true..
at that, would recognize your statement, here..
because you hold that spirit in your living years..
- human mentalities have many redemptions -
you have expressed an important one.!
more should take heed..

The dumb man cannot distunguish between a genius and a parrot. I see alot of parrot in this video no genius.
there are automotive alternator magnet kits for diy wind power generators .the last time I tested one for a customer was about 15 years ago so not sure if they are still available .that's the time when neodymium magnets were the hot thing to make projects, the ones I've seen came with a rotor cast from aluminum with magnets for 10 si gm alternators
I’m digging this project. I now have something to possibly do with my son in the garage. Thanks.✌🏽
Dude, I’m studying AET (Automation and electrical technologies) and this is right up my alley. You did a fantastic job explaining everything. It was a learning experience for me as well. My question is how did you convert DC into 3-phase AC?
Motor controller spits out a 3-phase pwm signal.
That's the speed controllers job.
Hey dude I want to try this experience because it is a wonderful thing. What do you advise me?
Absolutely impressed with your skills and determination, I would definitely continue improving and expanding the product base to a standard baseline and market it locally.
Cheers and don’t give up.
Sweet ride.
You've got a missus that understands our silliness as well, dude we're so lucky.
OLE'!
Your logical reasoning had you thinking it was something mechanical and it was…the positioning of the hall effect sensors. Nice prediction. The answer finally hit you after staring at it a long while, I imagine. Congratulations, you should be very proud; especially after that company sent such a discouraging letter
Great project, I’m impressed with your tenacity with the Hall effect sensors. They are not easy to understand at first and I thought you did a good job of describing their function. Really good job and video overall👏 Thanks.
Thank you!
@@austiwawa you definitely come through as genuine and guided by your own internal compass and inner light. Stay you. Stay true and i see success and happiness as two of your life’s major constants.
In depth knowledge, persistence in problem solving and happy riding! Excellent job
Thanks so much Hyuk! I appreciate it!
I agree, that kind of determination, accompanied with some intellect and ingenuity can take you far.
@@austiwawa I'll post this again here in case it may not have came to your attention. Just curious what you think about this: The centrifugal clutch idea could easily have worked properly, by either putting lighter springs in it, increasing the mass of the flyweights, or a combination of both, or else by getting a bigger clutch if that one was too small. I was also thinking you could have added a micro switch to the throttle, triggered by the initial first couple of mm of motion, connected to a relay supplying field power to the electromagnets. This would have eliminated the issue of the motor constantly spinning at a low speed.
Great final product though. Keep up the good work!
@@smallblockchevy1022 removing the clutch was better, because the sensorless controller couldn't spin the alternator as fast as the other controller and with hall sensors it was even better
and cutting the 12V field is a bad idea for the controller
You are a brilliant young man 👍. Our country needs many more like you.
Love your enthusiasm an knowledge of motors/generators I build similar projects I'm just much older an hopefully I have experience but your a good influence on people your age to know mechanics

Awesome job I made the comment about adding a smaller alternator to recharge your batteries and maybe double the time of the 30 minutes you have driving. I was wondering if you saw the UA-cam video where the kid in the third world country used a well-kept secret in using water to power his engine on a scooter. Is that really possible? It looked real.
I found that the best way to share my knowledge of electronics, was to play lead guitar in a rock & roll band, back in the 1980’s. We are so lucky that video was scarce. Now I study “the circle of fifths”. Cheers.
Converting the alternator was very impressive! But the most impressive part to me was that you are determined to find a solution and you did great job young man keep doing what you were doing with that same determination and you will go very far! GOD BLESS 🙏🙏🙏
70 km/h?? My scooter wobbling even at beyond 40 km/h! Great job! The Hall sensors made a world of difference!
Why would anyone thumbs down this video, it's super rad!

@@stevenbundy4336 caps on, this guy is not messing around
Thx/ Dankie. U give me an idea... With the trouble a week of so ago in Natal (ZA), it always good to have second engine on your motorbike. If or when u r strande on the road in an unsave place. The electric motor can get same kms away...(a slow speed is better than NO speed...)

You are an astute young man... you will go places in this life.
Well done on diagnosing the needed solution!
Great Video and very well explained. I wanted to build a similar project but I need to know how much power it is drawing (Amps, Volts and Watts), so i can pick the right controller. Thank you
Absolute genius, super impressed, just be a bit careful on that old bike, parts like the forks are under more stress than normal , wouldn't want them snapping on you. Let me know if you go into production, stick me on the waiting list.Somebody get this chap some funding from the stock market and get them in to production, recycling old alternators as well!
I can appreciate all the work you didn't show. Great video!
Your father's gotta be proud of you, him and your mom obviously did some awesome work together. 👍
We need more young people like you please continue and please Inspire other young people our future is in your hands. And I really do mean this our future is in y'all's hands God bless
If you ride at speeds higher than the bike is intended, reminder to check the axle bearings and grease.
I made a minibike in the 60’s from a stingray bike and a 65ccClinton go cart racing motor. It would go 50 mph and after every run the bearing grease overheated and spun out of the bearing housing. It would not take long for the bearing balls to separate from the bearing. Caged ball bearings were the common type at that time.
Those centrifical clutches are exactly what we used in the 60s when we made Go Carts and Mini bikes by putting lawnmower engines on them.
i had one in the 90s lol. loved it
OK, soooooo, I didn't like the Clutch. I put together a vert small lawn mower engine chain driven very small Mini Bike which started by dragging the back tire, jumping on... throttle pretty much took the place of the brake and to kill it just pull the brake. Worked great and My neighbor's kids loved it! Why not just turn the controller on and off? 42mph very good!
Literally why I come on youtube to watch videos like this.
Good to see finally there appeared a skid lid... Maybe making your brakes compatible with extra speed/ mass- it seems there are no levers on the handlebars, indicating the bike doesnt indeed HAVE brakes.
As a rider who has a intimate knowledge of road rash, this i believe isnt something to be swept aside, as you are rncouraging higher speeds to be attained with your ideas.
Also, this could affect not only the rider of such a contraption, but the driver/ rider/ pedestrian/ child that you might seriously hurt in the process.
Other than that, cool ideas..
42 mph. Nice! This is the type of DIY I love repurposed hardware with real results.
43.
Your conversions are taking away from the righteous to speed of 69 kph. WooooOOOOoooo!!! 😉
Nice one mate, I have got up to 45mph on my mountain bike going down a hill and that felt sketchy as hell. I can understand you not wanting to go faster lol. Will be great when the battery technology gets better and you can have more range without huge expensive batteries.
Great work done!! It also gave me more insight into the hall effect sensors, which has given me problems before. Thanks so much and keep up the great work you're doing.
This guy needs more Subs
This is borderland genius, kudos.
DO you mean Borderline? Cheers.
HECK YEAH!!!
FINALLY!
I waited for so long, and finally you installed the hall sensors on the alternator!!!
My years waiting finally paid off!!
The youtuber "Enrengineering" also installed hall sensors on his alternator go-kart
That's correct! And it seems I skipped some steps...dang it! It seems that I will need to perfect the car alternator go kart. 😅
@@OverbuiltByHenry the only steps that i saw you stepping and remember from head were the top speed tests with modulation of tbe PWM brushed system, and the hall sensors on the middle of the stator (you put on the end of it)
@@foxxyytofficial maybe I will try to put the sensors on the middle of the stator if I can unglue them
Thanks @FoxxyYT happy to see you so active in the comments! Enrengineering did a great job on his go kart!
@@austiwawa i am so happy to have you answering me
Since the first alternator video i tried to help people in the comment, not just in your channel but in others too, like Enrengineering's channel
Love it.HOWEVER seems very intense.
You should sell plans so a non electrical guy suçh as myself could
Tackle this project.
Hard work and knowledge and diligence paid off.
on the good side: you can weaken the magnetic field for more speed by varying the rotor current or make it stronger for more torque. free gearbox basically.
however on the bad side you wear the brushes and its less efficient since you have to waste energy to keep the magnetic field active.
you could also use it for regenerative braking by feeding back the energy in the rotor instead of applying 12v when hitting the brakes.
You're not going to wear the brushes by any noticeable level, considering alternators can potentially run hundreds of thousands of miles with no maintenance. It's a slip-ring not a commutator, so there's no slots to wear down the carbon
thing is if you use unfiltered PWM for the field winding, the sensors (and controller) will have to deal with the electrical noise
It would be interesting to drive the alternator with a VESC, and write a custom app for it to control the rotor field voltage. Since the VESC internally knows the ERPM, it could easily take that and apply it on top of a curve you define which determines the field voltage. Have the VESC output the setpoint to a DC-DC adjustable Buck regulator, and it be able to dynamically and automatically adjust for optimal torque and RPM.. I might have to play around with this.. heh. Another neat feature of something like this, is since the VESC directly can read the throttle input, it could also just disable the DC-DC regulator at 0 throttle. Thus eliminating the parasitic current draw at 0 RPM.
Need you around for an apocalypse
@@Hyratel, diesel trains have brushed motors driving the wheels that contact the rails.
These brushes have to be changed out regularly. I was informed of this by a (now deceased engineer). There are several sets of them. If you have a brushed motor, plan on having to change them out, there is no free ride.
This is awesome!, I think your power problem lays on the "Y" configuration wiring...try wiring the motor in a Delta configuration, you'll get way more power use but double your torque!
Better than rich rebuilds, you actually finish it in one video instead of 10.
Props to you for all your persistance and never giving up!!!!
Your efforts were worth it in the end. Very much enjoyed the video.
I like the way you worked through your issues even though the manufacturer for the controller said it can't be done, good job.
Really amazing work Austin! Thanks for the deep explanation on the science and physics behind the motor build.
Love your work ethic, and your persistence! Great job!
He sure has the curiosity, tenaciousness and knowledge to be an inventor / or great engineer. A definite free thinker. Kudos young man 👍
That burnout was cool!
This is such a cool idea! I'm getting parts to build a motorized scooter with 16 inch bike wheels, and this kinda gives me hope that I can still get it done under 1000$. Very cool work!
this contraption is quite sound, and can be doubled, inexpensively, considering the alternator(s) can heat up on longer trips.. on a scooter, you could easily carry two systems & use gel cell batteries, because they are very deeply charged.. you could, conceivably create a virtually non-stop cycle (or cart) with the use of panels, and precision bearings at shaft races.. good luck on your awsome scooter project..!!
Amazing! Your persistence thru the project makes you a hero. Learned a lot here. Thanks
That 3 phase cable magnetic gallop at very low frequencies was really cool.. So was the entire build, Nice 👌
You will make a great Engineer!! Keep it up! Never give up on a problem that is beating you down. There is always a way!!!
I have a bike, a new alternator, and a cnc machine shop so I think you've given me an idea. :)
I don't know but mabe CVT clutch would be great for this setup
@@edgarvalencia7523 Only if you could make it light enough. The weight killing the range is more of a problem than the power delivery method/feel with EV's
@@kylem7708 right on not experienced in the EVz but ya I fill like it could be tweeked for Les pull on the motor n more torque to the drive wheel good up hill climb but I only have tried on carts for a heavy guy but it is a hell of a build 👍🏼
I like to see people learning through doing progect like this.
Love this.
That centrifugal clutch can be fine tuned by changing the springs, much like the old advance mechanisms of automotive distributors.
aka. CVT🛵az well‼️😜🆘🔙🚀
Also adding weights so the clutch will engage harder at lower rpm
Came to see if anyone mentioned this
Dear Alternator converter to Electric Motor technician. FredNZ thanks U from "the ends of the earth" down here in South Pacific. My desire at 66 yrs is to put a motor on my wheel barrow so it can climb a short slope in my section.

Great to see you work through this. Id not thought of using an alternator. This is proper 'shed-built' stuff!
I can hear you now, HELP JANE! HOW DO YOU STOP THIS CRAZY THING?
Little tip about the rotor - if you reverse the polarity on it you reverse the direction of the motor. Also don't feed it direct with 12V, try feeding it via a 3W 12V bulb to reduce the current it takes and the subsequent heating effect in it. I've seen the results of bypassing a charge warning light on a diesel generator when the bulb blew, wasn't pretty! Using a 3W (or even a 5W) bulb will prolong the life of both the rotor and battery.
Other than that, great video and yes, HE sensors are tricky to get your head around - i found it easiest to think of them simply as a switch which changes state as the magnetic field around them changes.
Does the bulb balance the current or something?
For the motor, do you think these numbers could be reversed? /approximate?
"An alternator typically takes about 1 HP (horse power) for every 25 amps of power generated. So, a 100 amp alternator will require about 4 HP at full output."
@@dizzydinonysius As pointed out above, the bulb restricts the current to the rotor to prevent it burning out. As an alternator is a wound component, the generally accepted efficiency is ~80% (there are more and less efficient variants) and a 100A alternator will output 100A @ 14V. Simple Ohms Law provides 14 x 100 = 1400W, divide that by the efficiency and it needs ~1750W to drive it which is ~2.3hp. If the alternator was a 24V type at 100A this figure would be doubled.
However, reversing the figures isn't possible, the alternator in the thumbnail that heads your vid is 40A which would be ~560W@14V output. This means it's capable of being driven with anything up to 560W of electricity. As 1hp is ~750W, thaat would be roughly 2/3hp. Hope that helps!
Wow excellent work hoping one day having one like this kind of EBike
That's great man! Lots of clear thinking, I dig it.
Amazing skills you got. Tinkering so far to get your result. Put next motor as a crankdrive. On a geared bike.

Great idea, I would not have used a clutch on an electric motor. The way I would have fixed your problem is fixing a switch on the accelerator that would turn off the drive while at rest, I would gave let that little spin be the lowest speed you can ride as you accelerate.
I'd say the effort wasn't wasted. This was a good watch.
