Title: Has anyone played with using 3phase ESC for brushless motors???
Post by: Login to see usernames on September 24, 2021, 16:53:34 pm
Brushless 3 phase motors hooked up to a step up transformer like the lines on the pole. I have an ESC but don't have transformer to do the job at the moment. When they start it makes a beeping sound like there is a speaker in it. There is no speaker…

Video with ESC power fuel cell.
Having issues posting vids.. Follow link.. Tried many times to fix video posting issue. It appears to have something to do with YouTube turning my video into a short. Any help is appreciated.

Proposed drawing of 3phase esc

High output water fuel cell using brushless ESC
Take note of the fog or vapors coming off the top of  the cell.

Proposed drawing of 3phase esc

I always have asked myself where the third leg was connected to.....
Cool video, btw.
Do you have any power consumption on that test?

I have 2 vesc,s.........
Should also work, otherwise i could do something with  Arduino, ill gues......

Not sure about power consumption. Here is max power used so far.
11.1v Lipo battery and highest measurement of current 1.5amp

Also it does not just fire up you have to add so far absurd amounts of electrolytes so far I’ve tried KOH and Baking Soda. It’s all I have at the moment. My choice electrolyte is potassium bicarbonate but I do not have any right now.
I think the ESC needs caps and inductors to possibly tune it further. Still the cell produces fog off of it like fogger and changes torch flame just like fogger.

To control ESC I use a servo tester.

Just purchased some good old KHCO3 and some titanium foil to experiment with. Going to try hooking it around inside around fuel cell where I have a lead going to just the water bath.

Seems this set up is really touchy and only works with this wiring set up.
2 outside leads add a positive flowing to one and negative flowing to the other.
Center tap is neutral.
Hook up Cathode to center tube and
Anode to the water bath
(Near future I’m attaching a cylindrical piece of Titanium foil around the outside of the tubes to the water bath lead this will be oxygen collecting)

Water bath means the housing ? Or just a wire in the water?

Recently I used a piece of SS wire for the connection to the water bath. I just switched to a SS straw from the kitchen section.
I’m hoping I can add a liner of of titanium foil to the inside of cell container.
I’m looking to try cutting the titanium foil to a size that will tune the tiny bubbles into larger ones possibly using different surface space ratio to attract more H2 over O2.
