Good morning
Nice project 👍
Cool ideas !!
cool idea bro keep it up
I was going to experiment with a alternator, similarly, ibgot a brushed DC motor controller, PWM, to connect to the brushes, to vary the strenth of the magnetic field, and keep the coil cooler. I think the coil is ment to be pulsed in normal operation. To regulate output, I have heard it is most effiecent with about 3 vdc on the rotor coil. Great video..
Thanks James !
As a motor the efficiency depends on rpm, at low rpm the max voltage you can get without saturating will give you the highest output power, as rpms rise you want to drop the power to the field to reduce back emf and give more efficiency at higher rpm. For example at full 12v you may only have 2500 rpm max , it if you drop the field voltage to 5 volts it's possible you might get closer to 3-4000 rpm with the same controller. Pulsed dc to the field would be less effective, yes it can handle it but that's simply because that's what old style regulators used to use to regulate power (basically a relay that would turn off the field when the battery charge voltage was reached and turn the field coil back on when the voltage dropped to low for battery charging) but using a consistent voltage to the field would be more efficient, you just need different electronics than a relay.
Nice idea!
thanks very much. so how will the battery be charging as it is powering the alternator. can both the speed controller and the feed winding be connected together
Im still learning about electric. Can someone tell me what the limits are to an alternator? Ive heard 1500 watts or so.
Ive got a 3g ford alternator rated 12v and 130 amps which is a little over 1500 watts.
I saw a guy who ran his at 48v. He was using around a 1500w controller. Assuming he had a 130 amp alternator, would that mean hes running 130/48...2.7amps? This is what is confusing
Good project..
my question I have BLDC driver circuit with hall sensor. Can i use this circuit for this alternator to
Nice idea
How did the motor work, without changing the star winding into delta winding.
Will it work without changing the star to delta.
Well done, good job, until how many Ah battery is ok to connect it? 3:05 so to don't be destroyed?
Thanks mr electron you are genuine
I like that it's high torque low speed - what is needed for machines like lathes
Can v use single 12v battery for powering from both sides. Field coil and esc same battery
NICE VIDEO, MY QUESTION IS IF THIS CONTROLLER WILL WORK AT LONG THERM WITHOUT WARMING WITH THE ALTERNATOR, AND IF I COULD ADAPT A ELETRIC BIKE MANUAL ACELERATOR ON THIS CONTROLLER.
Use the output rectifiers for field supply. This does two things for you variable field strength and no power loss when the motor is not being driven.
The field coil should be voltage adjusted based on rpm, between 5-12 volts depending on if it's running at low rpm or high rpm.
THANKS FOR KNOWLEDGE SIR RIYALI YOU ARE GREAT THANKS AGAIN HARE KRISHNA
does it mather what side you rotate alternator ?
In some old tractor designs here in Europ comonly Delco and Bosch have capacitors on them if those capacitors fail the alternator does not charge baterry they also have another problem there exist left side and right side turning pulleys if wrong alternator is buyed also baterry dead empty.
So how to modifi such alternator and how determine in what direction it shuld spin and if you be acident buy wrong turning direction alternator how correct that mistake can the brushes be swaped or does it need to be swaped wires on the bridge rectifier as well.
There is lot confusion about that thing .
The laptop power supply is not usually 12V, it is usually 18V-20V, that would make it alone around 60W@3A
The 12V@2A is 24W for a total of 84W consumed/dissipated.
Some chargers are 15v and considering the full load current flow , voltage drops to 12v
Buen video, como calcular la fuerza del motor, rpm, potencia? Saludos
Trapezoidal or sinusoidal control? :)
If sinusoidal then is it FOC?
Good job..broww👍👍👏👏
What capacity alternator do you need to run a24VDC 1500W rated electric cooling system. Thank you.
Hello i have opened and alternator but i have 6 terminals coming out of the coil all with 2 terminals i really do not know which three i have to use can you help pls
Ok felicitari
what is white wire for? That is coming from the controller but is not in use.
i have zs-x11B module (with hall sensor connection) i want to use it to run bldc motor without hall sensor (alternator car modification) but not running. please teach me how to do that the bldc motor without hall sensor can spin using the zx-x11b module with hall sensor connection.
What if my motor controller has hall sensors or wires coming out that connected to hall censor ?
Can you make an electronic circuit for this motor?
Please send me the link of the video where you powered an inverter with the output of an alternator
Is there the same amount of volts at the output as at the input?
How do you work out that 1500W?
I like this video cause no talking
Can you guide me through purchasing the correct motor controller equipment to operate that alternator at it's full potential of close to 150 amps ? That would be great.
I will txt you the link when i find the required controller of rating 150 A or more.
@@MrElectron . Thank you for your reply and I will appreciate your help.
Hi!
I did some digging. 38 Amps is the max that is available in the no hall type.Perhaps if the a 24v volt or 48v alternator is available then the required current will decrease automatically.
Anyways, my employees are still looking.If it gets available, i will text you.

Although this controller has higher volt rating so its not suitable for your purpose.
@@MrElectron Thank you for all of your efforts.
Bldc motor or alternator which one is better for e bike project
I want 1 ton rotating 12 volt motor with less rpm ....I want to know which motor is suitable..plz suggest
Nice g
and when you instal a transformator 220v to 12v direct to the motor?
That's a different video.
Hello friend
This driver circuit can protect from motor back emf
Which motor is suitable to run electric cars,high torque motor.
Sir test this alternator motor and bldc controller in load like e bike
Hey hi! I saw both the videos great build I must congratulate you for not calling this a BLDC Moter. A lot many such videos that show alternator being turned into a motor claim that it's a bldc motor, when they have those brushes still installed on the armature!! And they also build bldc motors without magnets now that is fascinating 😂😂😂😂😂😂😂😂😂😂😂😂😂
Technically, if you just remove the armature and install a permanent magnet in its place, it truly becomes a brushless motor. There’s videos of that being done
The armature and brushes are just there to create the needed magnetic field
This is the video I been looking for finally someone who is just running one battery
Thanks
CAN YOU PLEASE TRY TO FIND A WAY OR SHOW ON YOU VIDEO ON HOW TO CREATE A SPEED CONTROLLER TO THE BLDC MOTOR WITH HIGH VOLTAGE DC INPUT LIKE GERARD MORIN DID....
I bought this controller that you listed and used in youre video ..but it looks way smaller than the one you used
Well that's bad... It has been more than a year since i bought it. They might have modified it to bring down the production costs.
saludos Mr Electron y si me vendes ya armado el alternador, para solo utilizar

@@MrElectron thank you alot
can I increase to 150 AMPS with 12v using this
Car Alternator
I didn't get your question
@@MrElectron upgrade the Amps from 120 Amps to 150 Amps
I got a RC BEC 30A speed controller connected to an alternator hooked to a car battery. The alternator spinned very slow for about 5 sec and stopped. Can reactivate but it repeats it's 5sec cycle. Any idea what went wrong.
You're probably using a sensorless controller built for smaller BLDC motors. What's happening is that the switching frequency is so high that it skips over most windings, resulting in poor performance. And it's shutting down as it's not recieving proper feedback from the other phases as it's too fast.
Either make or buy a sensored driver circuit. It would have extremely low torque and would need turning over to "sync".
alternator to motor
Hi I have a question,: why 3 wires if is DC? can you explain? also can you tell us the model of the controller you are using? thank you and best regards
It's pulsed dc timed between those three wires based on the phase angle of the rotor. It would be more efficient to use 3 phase ac because the windings overlap, in an alternator the windings overlap while in a bldc the windings don't overlap. This is why in an alternator the output is a sinusoidal wave form while in a bldc the output (back emf) is trapezoidal (basically pulsed dc).
Good luck

How powerful motor can be made by a car alternator?
You won't see Maximum amps, current draw until the motor shaft is loaded. Maximum torque will be with the motor stalled. Hook it up to a dyno to measure HP and Torque. you could use a generator as a dyno to measure watts and then times by 1.34 to get HP @rpm with a tachometer rpm reading.
how much RPM it will attains ?
This one's way to involved for me or anyone that doesn't have an education in electricity.
Is it ok to use alternator to e bike

Did it can be turn without pwm?
any thing is possible with electricity
Sir vedios are very good .pls give us supplier adress to get NO hall sencor. Motor controller.I need 1000 w controller working v 48v what is the price.can we get 1000w of power from truck alternator
Can I use this for ebike bro
Sir ye circuit kaha se mile ga please help or kitne ka hai
What's that's cirkid?
Sir can we use car 12vbattery for running alternator as bldc motor in bike please reply sir
Of course, but not directly. You need a driver circuit. Either buy it or make it.
Why cant you use one battery?
Bhai ye moter me se kaun sa current nikalata hai ac ya dc
Reply fast bro
Mr Elctron you mix up the winding terminology.
The "rotor" (also called "armature") has a "rotor winding" or "armature winding"
The stationary part is the "stator" or "field" so has a " stator winding" or "field winding".
The stator is not the armature, and the rotor is not the field :-)

Why don't you answer? How can i contact you? I need some help.
Any dc motor can be a generator or a motor,it just depends how you run it.
Some are easier than others, for example it's difficult to turn a series wound motor into a generator.
i know bro
I’ll use one of my low amp salvaged power supplies to connect to my e bike controllers to run their motors without using their batteries 5:20
is it possible to use a car alternator without a board or controller
no
Now, question is, how do I run this off 120 or 240 vac
There's no way you're using this on 120 or 240V AC. First, the US power system only has two phases and a neutral. These phases are 180 degrees out of phase.
An alternator is for low voltage only. You need a 3-phase driver circuit and a big 3-phase step down transformer to use. Just use an induction motor made for the job..

@@mmk4854 yes, there's tons of videos on TH-cam of people putting them in ebikes and go carts and the like. depending on the alternator you can get over 20 horsepower out of it as long as you have a good enough controller.
@@mmk4854 what more would you like to know about the alternator motor?
Is it possible to run alternator without controller
no
I don't get 3 phase ac or dc :-[
This is a three-phase synchronous motor
Sorry from a 12 Volt 100ah battery to a 24 VDC 1500W cooling system.
Can I use to make a table saw?
If you can find a way to attach the motor and pulley then absolutely. As long as the blade isn't too big and you don't cut too big of lumber it should work just fine.
I used one to power a drill press with a dead motor, and another to power a CNC spindle.
@@lazyh-online4839
Thanks .
It's need 1.5v to make magnet fild
The field voltage depends on the room range that you want. Lower rpm and higher torque means higher field voltage (8-14 volts) while if you want higher rpm and don't need as much torque you can use a lower field voltage (4-7 volts). I usually use a bldc controller (esc) with a BEC. That stands for battery eliminator circuit, it provides about 5 volts which is a good number for general purpose projects using an alternator as a motor.
What is the torque ?
The force when the rotor turns.
Try to hold onto a rotor with your hands when it is turning, and try to stop it with your hands from turning.
If the torque is low, your hands can easily stop the rotor from rotating.
If the torque is high, your hands will not stop the rotor from turning.
Useful videos should be uploaded 😎
Wats going on?

Yes !! Because the toque is good.. I am finding ways to increase its RPM Safely by taking all the circuit protective precautions
@@MrElectron wow....amazing....thinking to convert an old bike into electrick...hero honda splendor...what u think...how much speed it can gain...?
Few tests left after which i can reply to your query. Stay Connected
@@MrElectron ok bro...all the best...👍👍👍
I watched a video the other day about that. World's first 4 speed e bike it was called I think. They removed cylinder and mounted electric motor where the ohc would be with a chain drive down to the crank. Basically replacing cylinder and head with an electric motor.
When the video full RPM test
Found a way to run it for it's prime used, and as a générator you will be able to obtain 120 Amps of 12v DC

So , apparently it's 65w ...why you write (1500W) then??? ☹
So it's a synchrous motor
True, in a bldc the coils are isolated which gives a trapezoidal back emf waveform, while in an alternator the coils overlap which gives a sinusoidal back emf pattern, which means it's more accurate to call it a synchronous ac motor rather than a bldc equivalent.
@@lazyh-online4839 exactly my point
