Hey Dave,

You have not posted an update in awhile, I was curious what your new test's were showing?

To have a better control of the speed, change the throttle for a potentiometer, and thus be able to better regulate the revolutions, although I had to adjust the rotation as smoothly as possible. The revolutions of the motor were maintained between 2820 and 2900, the initial voltage that it is had in the exit of the coil with the focus, it was 100 volts, when putting another focus in parallel, the lighting fell.
after many coil and rotor adjustments, close-up, I achieved 125 volts of output at super brightness.
I put two bulbs in series to see what I got, the bulbs lit up well in the middle, the voltage between the bulbs went up to 150 to 160, depending on the combination of the bulbs seriously, different watts.

In the test of the coil, what has been obtained by the aforementioned generation of voltage, when the circuit is short-circuited, the generator is accelerated, but what I have not been able or able to accelerate under load, the coil accelerates short, but I have not achieved it under load.
I am waiting for the speed control to be able to adjust the speed with more precision, and thus make the evaluations.
I remember Mr. Dave's comment that some coils do not accelerate, that he had to do different coil tests, and how he balanced the different coil resistances, and the coils that had certain ohms accelerated or did not accelerate.
This is some work looking for the causes of things, trying again, making adjustments, making a new rotor plus magnets, different magnitudes, making a new coil.
I remember the videos of Mr. Dave where he shows the different rotors that he had to develop, the making of the coils, until he found what worked best.
I also remember Mr. Dave's comments detailing all those processes, as he guides us to what had to be done.
I began to read Turion's comments, for example I made a copy of his comments on the forum, some are not in the forum anymore, but the good thing I did back up his comments and I am returning to study.
I think I have to make another coil and connect it in series at best so if the acceleration is given at 2800,
I hope to do this when I try the speed control I'm waiting for.

The replica of Mr. Dave's project that I built is simple and straightforward, it has different measurements than the one I build it, so some data may vary,
I think that in my rotor the spacing between magnets I put them very close, since to install another coil I will not be able to put it continuous, and just as one realizes what has to improve, and it is work time, hours, days, investment .

I am all days it was hard and continuous work, one ends up tired and sleepless, but it is a pleasure to keep looking and improving, I work to prove myself the acceleration under load.

I continue with the project until I achieve what Mr Dave has demonstrated, and thank you for your guidance.
Thanks for your attention

To get the 36 volts, I had to use the car's battery, but I had to solve the charging problems, to keep them running constantly.
With a computer power supply that I have kept, I made the adjustments to have a permanent charger at 36 volts, and thus have continuous work.
I was missing the regulator, but anyway I made it operate without it.
I started operating the motor at 36 volts, and the generator with the 12-wire, 4-series, 3-parallel connection, with a 72-watt, 130-volt bulb.
The brightness of the spotlight is very bright.
Remember that the motor had bought it with its speed control, I installed the regulator and its accelerator. This allowed me to control the speed in a way, the problem that the acceleration or speed control is the type that motorcycles bring, and it makes it difficult for me to maintain the turn

hi greetings everyone
These past days I was working very hard.
The mr of the lathe workshop spoke to me, who already had the part for me, the shaft coupler.
Well I went for the part, to start working on the generator and the 36 volt 800 Watts ZY1020 motor.
I needed the batteries, I have 2 car batteries that I use for when I do not have electric power from the grid and with an inverter I get power.
I continue in a moment more

ok greetings mr Dave
and everyone on the forum

I spent the whole morning and part of the afternoon, checking a coil that I made with a ferrite core, take advantage of some wires that I do not use in wanting to make some multi-core coils in a car generator, what happened is that the wire gauge exceeded the measurement the alternator slots were 12 strands of # 20 cable,
I made the coil with a ferrite core wind the 12 cables in parallel the length of each cable was 6 meters.

I began to carry out the tests, and tests what I could obtain was that in court it gave the acceleration, I did not find the acceleration of the speed under load, I do not have the motor with a higher speed of 1500 rpm, it is with the machinist of the lathe is doing a motor-shaft coupler.
During the test, the ferrite core hit the rotor and broke it. I took off a piece of wing. It helped me to do the tests better. The only risk and danger was that the piece flew, fortunately I was not hurt.

It remains to test the coil that I already have 12 wires, from Dave's project, put a ferrite core, adapt it since there are no exact measurements for the coil core in question. I'm going to have to buy them and see what measures work for me.

Or do I make a new coil adapted to a new core


Boy, every detail of the projects takes time and effort.

I am left with the pending to continue and acquire the pieces to do the tests.
