Everything but what I need to see,
Totally 🤦♂️🤦♂️🤦♂️
No face no case
Great vid... but 15 minutes of showing us how to take out screws w pliers was painful. Then excessive time spent showing soldering... then skipping the whole wiring to the power supply, motor controller etc was kinda odd. so you are varying the current to the rotor to change the motor speed? What voltage resulted in the highest motor speed?
Exactly, this guy has 2 4k cameras but cant be bothered to buy a Torx bit set??
😪🤕🤒😴😴😴 true I felt sleepy in the end of video
Just apply a low voltage to the rotor where the voltage regulator would wire in, have a battery attached to a dc 3 phase motor controller. One of the phases to each of the coils, Done. You vary the voltage from the motor controller, its pwm which give should a percentage of the full battery pack power depending on how much you tell it to.
Yes. Never seen anything like it. Sheeeeeeeeesh.
Yea dude you are so right it made me sick watching this lol
Why not showing how you wired it to your power source .
Just apply a low voltage to the rotor where the voltage regulator would wire in, have a battery attached to a dc 3 phase motor controller. Done.
Battery how voltage?
So many of these BLDC conversions stops at explaining a lot of information. First, the arrangement of the three wires does set direction. If you knew the 120 degree order of them, you can then predict the direction the "motor" will spin. But everyone of them simply apply the three wires to the controller and never explain about that issue. Secondly, I have yet to see even one talk about how much torque these conversions have. If it simply spins, big deal. Now if it has some serious torque where you could use one for making projects that typically takes some HP, then that would be something to measure and talk about. So many good uses for a serious HP motors these days. Tell us how much power these conversions have... JMHO
4000W or more can be achieved with a good controller and battery together
"Fixitmoditbreakit" did this test
The order doesn't matter. It's can only be applied through one star direction the order doesn't matter. So you can't screw that up. To reverse direction you just reverse the the polarities of either winding or brushes.
And you too like all others didnt explain where and how you connected the three wires including the wires from the brushes.I give you 5/10.
Most of it was great. What did you plug the three wires into and how.
Чем выше ток возбуждения, тем ниже Kv и выше крутящий момент! С полностью возбужденным мотором (@5A DC) можно получить минимально возможные обороты, и следовательно, большой потенциал в наращивании напряжения питания контроллера ESC. Двигатель может выдавать гораздо больше, чем паспортная мощность генератора, из которого он сделан. Еще надо добавить, что выходные токи генераторов такого типа - не редко достигают 80-120А. Это продиктовано сечением обмотки. Самодельщики же используют токовые возможности двигателя лишь наполовину в лучшем случае. Еще неплохо было бы застабилизировать ток обмотки возбуждения на уровне 5А каким либо импульсным стабилизатором тока.
You might try a 1/4 inch nut driver on those torx bolts, thats what I used on the torx bolt on my alternator. Good video.
Please show me the connections to the power
How is the video? 😂
Dont forget to re pack the bearings with grease when you take the alternator apart.
after soldering the 3 stator coils you did not show how to wire them to electric source.
They connect to the speed controller, does not matter the order
@@MadeEasyChannel you can show either
How to wire to power source without controller
Or
How to make a controller.
Otherwise your video is slower, but the same as all the others on this.
Why not use a12 point socket to remove the torx head bolts?
Not sure where it came from or where to get one, but I actually have the right socket for those bolts. I'm sure a regular socket, maybe 6 or 12 point, would still work. That's something I should check.
HEy, if you're going to be serious in this project, i would recommend for you to use a VESC controller, they're not that expensive (50-70USD from what i know), and they are fully programmable, so you can fine-tune it to run perfectly with the alternator
lol does that spool of solder say RadioShack on it, i thought they all closed down.
Well... That's certainly one way of turning a really short video into a realllllllllllly long one without even explaining the supply to the altered alternator!!!!!!
What's the advantages with converting an alternator over using a starter motor or one out of for example an electric fork lift?
You can get used alternators for pretty cheap
Starter motor will burn up quick.
They are made for quick with heavy torc use.
Forklift motors are expensive.
Obviously not brushless but a great project
Brushless hybrid. I know, through me off at first, too. The reason they say brushless (hybrid) is because the driving current is not flowing through the brushes. Only a couple amps to generate the field. This barely wears the brushes so they last MUCH longer than they would on a conventional brushed motor.
Where are the three terminal wires from the alternator connected to after the soldering?? Please give me fast response.. I'd love to make mine
I have tried on 2 occasion to make this motor out of a alternator and this do not work, have anyone else tried this and if so do it work for you
We had some luck, and we got it turnin' real nice. It works really well, it's very powerful once it gets going, but the starting torque is quite weak.
NOTE: we used an ESC from an RC plane, we'll use a wired hand throttle later.
Here's a video for proof:
ua-cam.com/video/UpU3wQyp5qA/v-deo.html
Use a 48V sensorless controller and you will see better torque
@@foxxyytofficial I do have a 36V sensored ESC, but it requires extra hall sensors and a 10s battery pack. And 10s BMS are quite expensive. Also, I was powering the rotor coil with 3.7V.
@@imnotbeluga007 you can add hall sensors to alternators, Austiwawa and Enrengineering did it
And for the rotor, use 6-12V depending on the stator voltage
@@foxxyytofficial please at what state voltage should I use 6v or 12v for best performance.
I'm planning on running this alternator at 60v+ for an ebike project
@@Yangmist3r 12V will give more torqur but it will heat more, you will need to make sure that a fan will push fresh air on the coils and the stator
You forgot the most important part. Wiring config. Wtf
How did you connect the three wires to power 🤷🏽♂️
Can you explain, what is the DC power supply connected to? also the silver box and all those wires are connected to where?
The silver box is a bldc controller
The dc power supply is connected to the brushes
I'm with you, Ray. It's the most important part of the setup but NOTHING is said about it.
Great video!
Strangely when you cranked the current and voltage on the brush, the motor (alternator) rpm was slowing down.
Do you have any thoughts about that?
So, what's your suggestion for the voltage on the brush, if we expect faster and more torque from the motor?
I am not sure, I will be making another video with different voltages to see what works best..
@@MadeEasyChannel cool, thanks!
I'm about to do ev conversion project, this video helps a lot. 👍
if cranking up voltage/current on the coil (the slip rings) the rpm decreases and torque increases, and if turning down the RPM goes up and torque goes down
when you increase the rotor voltage and amp, it will increase the rotor magnatic field.
when the magnatic field stronger, it hard tu turn.
that why the motor spin slower.
you can check it yourself.
spin the pulley by hand, lower voltage and lower amp are easy to spin compare to high voltage and high amp.
@@bro-shamsulnubairi8689 yes, that’s make sense.
Then the ideal usage would be using “adjustable” power supply for the rotor, so when we needed torque (i.e. at start/hill) it could provide more voltage/current, when we needed speed it could lower the voltage/current.
from where you have buy the convertor please share the link and how much volt of battery you are using???
I added it to the description
how do i identify if output current is dc or ac? my cheap multimeter don't have this function. tq
It would be nice if you put it in the wiring diagram, what you hook up to
Can you tell me the voltage and amperage required to run this
Can I use a rheostat to deliver variable power to the "motor"?
No, you need speed controller. Rheostat cannot handle the Amperage the motor requires
All we observed is you soldering wires. You did not show the connections to the controller or power supply? Why not?
What you dident make it brushless tho
So if you put 12v dc to the rotor and 3 phase ac to the stator than this becomes synchronous motor ?
Pretty much
May you show the diagram of the connection please sir
Feeling same here 😔
@Kizit
The way he connected things to the motor was 1) connect dc power to the rotor electromagnet winding, 2) connect the storebought sensorless ESC controller wires for phases 1, 2, and 3 to motor windings a, b and c in any order, and finally 3) connect the positive and negative power wires to their respective spots. The only things to watch out for are to not mistake the positive and negative power connections for each other, and to reverse the connections on motor windings b and c if you want to reverse the motor direction. Most ESCs will let you control direction through the ESC though. If you want to build an esc instead of buying one I suggest you watch Great Scott!'s DIY or Buy video on ESC controllers for a "lay of the land" so to speak first.
if u don't have torques wrenches. u may have a flat head screw driver that will catch at
off go the side
is it still working until now..?
Es bueno, pero cuando le agregas carga en la polea (la transmision con las ruedas), el consumo de energia ee eleva muchisimo
Wowww!!!amazing! Good job.
It posible tha,this modificade alternator charger the same vatery at the same taime when the alternator Is workin at the ame Time whe It using 12 Volt vatery motocicle
What car did this altenator come from?
you think this motor is powerful as 1000w hub motor? I think Its a little weak (maybe good for a kids truck that goes 25km\h)
Check the new Austiwawa video, he got 69kph on a bicycle, so probably with a different gearing you could get 40-50kph on a truck or kart
Considering most alternators provide 80 to 200 amps at 12 volts you would have at least that many kw of power that the motor can handle continuously. It would be something like a 3 to 5 hp electric motor. Or equivelant to a roughly 7 to 16 hp gas motor. Pretty powerful. Some alternators are designed to spin at 8k to 16k rpm in normal use too due to the belt gearing on the engine.
Almost like a brushless motor?
I would,n hire you to waler warp around!
Don't be lazy use a lighter or small torch to shrink the heat shrink tubing
Wt is it ?
What type/brand is this particular alt? Which auto was it used on?
I just bought a random one from eBay
@@MadeEasyChannel Does it have anything to identify brand or mfgr? I understand a delta configuration is much more efficient and useful than a wye--better torque and higher rpm. I want to E-bike an old 1960 Schwinn and building is the funnest part of all.
GREAT VIDEO, most I have watched seem to lack info or assume knowledge.
The right tools would have this a 5 minute v
Merhaba video içeri konusu çok iyi , fakat ayrıntılarda çok fazla uzun tutulmuştur..

A similar generator pushes my car with a driver and a passenger. I like it. I also like to make interesting projects, one of which I do on my UA-cam channel
You have done the best job explaining this , but I’m still having trouble
The rotating part is a wound rotor. The outer stationary part is called a stator. The rings on the rotor shaft the brushes ride on are called "slip rings. If you put power in the brushes, you get a synchronis motor. The 3 line input for the stator creates a rotating field because each phase is 120 degrees off from the one next to it in the sequence. If you switch any 2 leads, you change direction of rotation. Please don't try ro explain the science, just do it.
It is neither brushed nor brushless, something in between?
it runs from a brushless controller
just uses brushes to feed the coil
both,
brush and brushless
Donde se consigue el controlador en que pais yo soy de argentina
@@alfredoserrudo7908 aliexpress
From an electronics control and design standpoint it is effectively a brushless motor that has an electromagnet instead of a permanent magnet for the rotor. If you were to modify the rotor to have permanent magnets it would be 100% a brushless dc motor.
You did not show how you wired the alternator to the power supply thanks
What size battery will run that 24 volts?
The controller needs 36v
You run 3 12v batteries to get the 36v
@@user-cq8iu6et8l thank you
Where was the "brush less" part? Looked to me like you were applying DC power to the ROTOR (not Armature) through the brushes and slip rings.
The brushless part is the fact that you run ac power through the 3 phase windings just like a bldc motor. You can run it with a esc designed for a sensorless brushless motor or with a 3 phase variable frequency drive. You just have to power the rotor windings since it is an electromagnet instead of a squirrel cage or permanent magnet.
@@joshnabours9102 So as I said, applying DC power to the rotor through brushes and slip rings. So NOT a brushless motor. A standard DC motor applies DC power through the same brushes except the rotor has a commutator instead of slip rings.
@@TheCSRTech you are emphasizing the most insignificant part about the motor. This alternator is effectively a brushless motor with an electromagnet on the rotor instead of permanent magnets. The slip ring only serves to maintain contact with the spinning rotor winding where with a brushed dc motor the brushes serve as a way to change polarity of the windings to make the motor function at all. If you glued magnets onto the rotor this motor would be a 100% brushless dc motor. If you placed the 3 phase winding of an ac induction motor or bldc motor in the rotor portion of the motor it too would need some form of slip ring system to maintain electrical contact with the windings. They wouldn't cease to be induction or bldc motors though.... A brushless motor is only a squirrel cage induction motor with permanent magnets replacing the squirrel cage of the motor anyway.
@@joshnabours9102 Significant or not, if a motor has brushes it is not brushless. Simple english; not clickbait titles.
Let us back up for a minute to clear up something. Slip rings do not preform the same function as brushes. Brushes purpose is to switch the direction of dc current as the motor rotates. Slip rings purpose is to maintain constant contact with a portion of a device capable of spinning more than a certian number of degrees. This alternator motor is a brushless motor that has slip rings in order to allow the rotor to be an electromagnet for simple power output control and greater reliability in the harsh conditions of the engine bay. You can also find slip rings in non motor applications such as tank turrets or other rotating assemblies. Wires do not twist infinitely after all. They were also once used as the on/off power contractors on certain older motors controlled by mechanically linked levers. Brushless and dc motors can have slip rings, but only brushed motors have brushes. Alternators do not have brushes. They have slip rings. Have you ever seen a 3 phase brushed dc motor before? No. Because dc motors directly run on dc which does not have phases. I rest my case. You are simply incorrect.
You didn’t show after 3 wires where they are connected
from wireing into operating ...you did not show how to connect the power source
why don`t you use a flame on the shrink rap?
I was in the garage, with wood all around, I thought of it. But used soldering iron instead
@@MadeEasyChannel I meant something like a cigarette lighter.
Great video. Congratulations
May I ask What controller did you use it?
I added it to the description
@@MadeEasyChannel Thank you !!!
Watching people struggling to take something apart without using proper tools is not my idea of a good time.
SCREWS ARE CALLED INVERTED TORX
watched the whole video and you didnt even show how you actually hook up the power to it
Just like others to the end they skip not showing everything
pls anyone can give me a motor controller?
The flux is already in the solder....
Can you make a diagram for the connection without using speed controller please
It is impossible without speed controller
@@foxxyytofficial no.
Its just that no one has shown how to do it.
Its like watching the same video 30 thousand times.
Someone needs to show one if two.
1st how to do it without a controller
2nd how to make a controller.
Otherwise, it the same video as all the others.
@@baddog9320 china have the controllers

No one delivers to my house. Been trying for months to get a drop point in the city. Which is 100 miles away.
I have mine set up but it doesn’t spin when I put 12 volts to 2 of the wires
Same altanator that came off of a Bravada
U skipped all the wiring in the video
still need help?
@@foxxyytofficial no just had to buy the thing
This has brushes and is not BLDC
people get so triggered with this
the brushes don't spin the motor
If you want to be technical it is a hybrid induction motor. However, the main difference between this alternator as a motor and a bldc as a motor is that the rotor is an electromagnet instead of a permanent magnet. And the poorer power efficiency. You can drive the alternator motor with a sensorless esc just like a bldc motor or you can use a vfd like a 3 phase induction motor.
Alternator to motor
FIND A SOCKET THAT FITS OVER THE TORX
Where Åre The bruchless part?? Make me hheehee..
Why did you skip the wiring of brushes? The connections of three wires to controller? Useless tutorial.
Use the right tool for the job. A set of Torx drivers is a very cheap addition to your tool kit. Pliers destroy a lot of fasteners that you might want later on. Not only that, but if you round off or break the fastener in question before you get it removed, you complicate your job significantly. Use the right tool for the job. Also a cigarette lighter will do a nicer job of tightening heat shrink tubing, better than a soldering iron, anyway. It appears you are using flux core solder, so there is actually no need to apply extra flux. Otherwise, good vid, except it probably raises more questions than it answers. Nothing wrong with that, though.

Worst video out there. The biggest question out there is what is needed to drive it AFTER the regulator/rectifier is bypassed. But you said ABSOLUTELY NOTHING in that area.
🥱
Not a bad video , But your soldering skills need a lot more practice 👍
😅😂🤣
Over 26 wasteful minutes of showing stripping the back of the alternator and soldering three wires.
They are all hiden the last step how to connect 3 wires and neutral wire. All the same shit
You could have shortened the video to 7 minutes because it became very boring, despite your efforts and the good result, but no one wants to watch a half-hour video on a simple topic
Why do other guys need to use two motor controllers but you and some other guy always use 1? What's the fucking secret. I can't clearly see where you connect the positive and negative ends of the brushes.
Do you really have to show the grueling torture and time consuming detail of every step?
yes. if you don't like it, don't watch it.
