my wife enjoy’s the engine running…

Do not exceed 60 volts on that!
There is no " Phase paper " insulation between the windings of the coils.
If a coil from one phase is touching the coil of another and the potential between the two exceeds about 120 volts there is a risk the insulation will fail.
Now in my world I know we the good enamel wire is safe to 120 volts, but I have no idea what you are dealing with and I can guess it was never designed to run at high voltages.
So 60 is probably safe but 120 is absolutely out of the question
Previous experience with a 13 cubic inch Briggs and straton direct driving a 100 amp Leece-Neville taught me you can’t start under load with weak batteries.
The engines in this size can carry the load once you get above 2500 rpm.
Your wife has a charming smile, and seems a natural for demonstration videos !
Clearly she has an interest in you projects.
My wife says I drive too fast and yells at me ha ha.
She says I should do more work around the house and less playing around.

Hi Koen
What power can support your pwm?

Hi Wallace,
No problems with the alternator here, its been extra dipped…
My wife and i teamed up since 4 years now, building together… somehow she’s able to teach me…

Hi Thierry,
This pwm can handle 15 amps, i restricted it to 5 amps for the field windings of the alternator.

Hi Koen
how do you know that the coil of the rotor of your alternator can handle 5 amps

Hi Thierry,
5 amps is the load that it pull’s at 24v input

Hi Koen
I suspect that this observation is not obvious!
Do you feel that coal consumption of this setup (+ engine alternator + dc motor) is comparable to the setup (motor and transmission)?

Hi Thierry,
Running with the batteries and creating a constant load is the most efficient so far…
If doing gentle with the DC motor only, then the consumption is less then motor-gearbox… but i am still learning how to…

how can I know the level of electrical insulation of a generator?

mine is dipped in when i was present…

I don’t suppose that you documented the process?

i tried to memorise…
dipping in… dipping out… wait… and dipping in again…out, wait, hold…hot stuf…

What sort of dip did you use? Do you have to heat it first? How much do you need to take apart before the dip? Is there a cleanup process after the dip?
I’m guessing it wasn’t as simple as "dip it and take it out.

hot liquid dip they use… brittle when on the iron, easy to remove from the stator, but sticks on the copper windings… ( melts with the old protection layer ?)

Hi Koen
I understand that you want to run at constant speed?
I understand that the alternator to several poles can generate power at low RPM. what advantage it gives?
I do not understand the advantage of several poles for your configuration

Hi Thierry,
its more run at constant load i guess.
The low RPM gives me the advantage to choose the lower RPM on my engines to obtain already a needed amps to charge. So the range from 2200 to 3600 RPM for the engine and the range from 1400 to 3000 for the generator…

Progress on the Hybrid…
Battery’s came, inverter on the way, preparing for show next monday…
Installed some nice gizmo…
Having fun all the way…
