Shorting the gen coil with PWM? .. and other things.

Hi Al, Do you have a still shot of that rotor?
In motion it's hard tp tell.
I'm assuming they're magnets , the black blurs ?

Hi, yes, the 7th post on this thread is a still photo of the rotor.

Its not always possible right away but get scope and learn how to use it. Then you get true test of what kind of power your dealing with.

I am happy for ya.

Thanks Matt, I am on it, I ordered a cheap hand held scope, and I am waiting for the package, it comes from china.

best,

Hi.
You may be interested in my attempt at generator coil shorting from a while back.
Pulse Motor Generator Coil Shorting Test
As you can see in the video the brightest purple neon flashes happen at a certain sweet spot, TDC.

Very nice, you are shorting with pwm. did you try to fill caps with that? I want to know what is the difference between shorting at peeks of the sine wave vs shorting all the time with pwm like in your video. (regarding drag and time needed to fill a cap to a certaint point).

question: why mosfets and not bipolars?

best,
