Maybe possible idea for duplicating effect of Holcomb and others

Hello again,

Here I have uploaded a third image from that same testing...which I wanted to discuss plus give my opinion.

I believe (am pretty sure off) that He is using the Sensing Type ESC for this test, just because it keeps having an "inactive" phase during intervals, and so switching on all 3 phases the inactive one..and this is done by the ESC Processor, in order to detect the right magnetic positioning of the rotor. So, that inactive (not sending power to it) circuit of coils, serves as a sensor, which feeds back the rotor magnetic positioning.

And that is why we need a Full, Sensorless Driver here.

.but I know you do not have one working...However, this will work as well just for one signal of the 3.

maybe you forgot about the good old Lissajous pieces.
The CRT tube has four plates. And they are not afraid of overexertion.
It's just hard to interpret the resulting image.
This is how the hungry get out of the situation, who have nowhere to wait for help.

Hello  to All,

I put together the basic schematics for Zafer Yildiz circuit based on 3 FET's...simple.

I may do sometime next week the symbols electronic schematics, as this is just as we saw it on video.

I found the best FETs are the AUIRF3205 which are Automotive Rated Spec's...a bit more expensive (like $4.36 USD ea) , but worth it, because they are heavier duty than typical board mount types...

I also uploaded the PDF Data Sheet for that FET...

They are 55V and 98A Rated N-Channels MOSFET.

Hello,

Something I have noticed on Zafer Video...

Note when He accelerates the Alternator-Motor, with Potentiometer, the PSU shows no Amperage increase?
I find this property of this ESC, very useful for our purposes...
Here I uploaded two images from video...first one when he starts and a second one, once He accelerates Motor, note the Voltage increase,  while no amps increase.


Edit 1: Never mind, no big deal, I noticed He has CC on...or Current Control (CC) Limit.

Hi UFO,


Thanks for the nice schematic.  Also the IRF 3205 mosfets he is using are rated for 110 amps at 55 volts.  I have used them many times and they are pretty durable.


Thanks again for your input.
