((Help me please!! alternator delta conversion as a motor))

A small conversion for cycle which costs cheap! MDR :lol:

You need 200A rc controller to be able to pull 30A+-
Are you planning to use the alternator for an electric vehicle?

Yes, for a small trottinette. (Low-cost).
No need to toss a big fortune inside.
 
Its going to be expensive to make enough power with an alternator for an EV
Maybe just go with a brushed motor and controller?
Do you need to use the alternator or does it just need to be a cheap scooter?

No, one conversion alternator costs little, and the truth e-bike or e-scooter costs (1200-2000$) my friend :wink:
And one kit for e-bike conversion costs (250-500$, from china), I want just as the video above for (50-60$) maximum,
and so to act like an idiot a few minutes around my garden, it is tous.
I do not want to go to my work with. LOL :mrgreen:
 
I see, Cool 8)
You will need a strong controller. That 80A would only have been good enough for a little load.

Wait a moment! Why do you have your servo tester connected on IN side? PWM signal for the ESC comes from OUT side! + and - are shared by both sides.



YES, on my picture which I posted, PWM is on IN, but I understood later by seeing video YouTube, which PWM goes side OUT, no concern. :wink:
But in this way, not work not also.
How I can make a test for ESC, to be sure that he is good Dead?

You can try to run other BLDC motor, old hard drive main motor for example

Old main engine of the hard disk for example, you mean what exactly:?:

Thank you for the link skalabala, ha ha ha :lol:
I was far from believing that this thing is possible :!:
I knew not, now yes. :wink:
I have a hard disk, but I want not damaged because I have data inside.
I tried this test with mini ventilator 12V of pc, and it weakly turned then ESC makes beep beep....

How did you accessed phase wires or this ventilator? You could take old CD or DVD rom motor as well.

P.S. Go to any computer repair shop they will trow at you with damaged HDs and CD roms.

OK parabellum, I would look for old hd, dvd or cd reader.
Concerning the connection ventilator, he has 4 wires (black-, yellow +, blue, green, for the speed I think?!),
then I connected black, yellow, and blue, or green, towards 3 wires ESC.
The ventilator work weak, saccader, and ESC to emit Several beep.((((((

If colors correspond to IN-OUTs of phases, then ABC are your ESC phase connection points.

Sorry but, for repeat the connection "delta" and be sure of myself!
I connect the points blue together, green together, then red together, or, A+A, B+B, C+C ?
Thank you for your patience Parabellum :wink:

PS:My magnets rotor and stator were with thickness get greasy enormous and to turn with difficulty,
but once to clean, then to sand with wire wool, so turn better, and I put a magnet on them, and magnetism better also.
I make a test after and give the result. :mrgreen:

A+A, B+B, C+C then connect each pair to ESC phase wire.

CPU fan does not have phase leads outside. It has tinny controller inside and cables are 1-,2 +,3 PWM in,4 speed sens. So I do not expect it to run from ESC phase wires.
 
It is wonderful! He run finally!
To connect: A+A, B+B, C+C.
It is also necessary to wait the "beep" starting of ESC, and then to activate the servo tester, thus my error also It is when the ESC makes its "beep" in the first one, was that I disconnected the wires by fear which the ESC warms or burns.
Also, I cleaned rotor and stator with straw of steel, and completed work then! Happy! :mrgreen:
Here is a short video of my driving alternator, and an picture with the handle accelerator (effect hall) for the next stage (she will be connected to potentiometer servo tester).
Thank you Parabellum, Skalabala, Harold in CR, to be to interest in my problem.

I would give another video with handle accelerator connected,
I go tempted also, to lower the tension of the rotor, of 12V in 3V, with a " deck divisor of tension ", he can run even faster!, to test!
More, I would add one li-po battery 6S 22v, with big autonomy, li-po is low weigh against other battery.
I would explain quite the conversion for those who will wish. :wink:

Nice. Glad to read it!

P.S. You know, you can connect your hall throttle to servotester, right? :wink:


Thank you parabellum for your contribution. :wink:

Yes it is possible, a guy welded the wires of this handle effect hall towards servo tester and works very well.
I go tried to make tomorrow.

Hello Parabellum, before welding the wire, and burning out the servo tester!
To see on picture, the rear view of the card servo tester, because I hesitate between 1 or 2(middle),
to weld the wire jumper on brooch "Signal" IN, in 1 or 2 of the potentiometer.
I know that it is necessary to delete the button potentiometer, you worry not.
Cool of your answer. :wink:

So, exactly what determines the speed ? Is the servo tester adjusting the field weakening and the twist throttle adjusting the volts-amperage to the motor, all at the same time ?

Electronics is what has me baffled.

I think that the servo tester works with a question of frequency simply, and he replaces " the recever of frequency " wirelessly, as well as " the transmitter ", wirelessly also,
for make a fast test of good work of servo etc...
Thus, by diverting the servo tester, the handle effect hall just replaces the button, to be better comfortable to accelerate.
Alternator can run even faster with more voltage, and also by lowering voltage to the rotor (as Widodo explained), but to take account of the maximum voltage to authorize by ESC, for example my ESC 80A, takes li-po battery 2S-6S (7V-22V).
