Hi Laurent,

Good to see you got the screen demo to compile and upload.

It looks like you have accidentally removed a comment mark in the UCC code. When a line is commented it has a green color in the editor. This means the line will not get compiled and uploaded to the Arduino. A comment line is just for human reading.

Make sure the line is commented properly by using two forward slashes at the begining like this:

// This line is now a comment...

If it is not commented properly then the compiler will treat it like program code and try and compile it with error.

You can try firing a FET using the 5V signal. Yes there is a chance that if youblow your FET with high BEMF then some could find it´s way back through the gate and damage the MCU. If your FET doesn´t have reverse bias protection diode inside then put a reverse bias diode over the drain and source, to protect the FET and thus the microcontroller unit (MCU). You can also put a neon across the drain and source of the FET to protect it further.

Yucca.

at all

going on to design the power UCC motor for my ultralight i have some questions to you about the windings

on my Lynch motors   there is no normal winding  that is to say there is no coil + core + magnet  there is solid  long straps of copper "winding" (around 1 centimeter width  and 2 mm thick)   as if it is a one turn of heavy strong winding.  If you see at the patent of Cedric Lynch (simply ggoole it)  it seems to be an array    in my motors there is an array of 143  single turns winding all arround the rotor and all theses array are separeted by the mean of laminated cores   and i can say to you that this motor works very well

now to my precise question

would it be possible to make a UCC with one single copper wire    perhaps 5mm diameter  to support 300 pulsed amperes to motorise the 9 magnets arrangement  (as i proposed at the beginning of this thread) 
in fact how is the best way to transfer the electrical power to the copper wire to get the most electromagneticforce         i speak here  up to 13 -15 KW   (about 20 hp)

thanks

@Yucca

i have less time now but i will soon ask you a lot of questions about the arduino   thank's

The most power depends on your amperage. If say you can provide 100 amperes then try to get as much WINDINGS as possible with a wire that can handle that to make a strong field. On the other hand this not being a 100% DC motor you have to take self induction of the windings in account as it can become a negative thing.

Since the current is thought to flow principally along the edge of a conductor, it might pay
to silver plate this wire.

@ Paul-R

yes very goog idea   and if we go simpler   why not  a single copper tubing ? for instance   

i can get easily  outer diameter 5 mm and inside 3 mm copper tubing  and a lot of other dimension

thanks for the info       

any body  about  UCC   with one winding-tubing for very high  current  ??

all the best

Laurent

@all

concerning  the one turn tubing UCC     i have seen that this could help but only at very high frequency         so for the purpose i am thinking of  it is not very usefull

but my question is always up to date

the ampere-turns calculation says 

for a given electromagneticforce of   let's say X-force

i can get it with

300 amperes and one single turn coil

or 300 turns coil on one ampere

or 10 turns coil  with 30 amperes

or 30 turns coil with 10 amps

and so on


so what have i  to calculate to absorb  a power of     15 kw (about 20 ps)  with a battery of 51.8 volt nominal and 40 aH

if somebody can help


thanks

Laurent

Nice motor , here you see it go from pulse mode to Lenz by advancing or retarding the timing
