Pierre's 170W in 1600W out Looped Very impressive Build continued & moderated

Great to see it rotating 

For the 'x' question...the one to change is the one without // in front of it, x = 5.
(at 3:33 in your video)
The line at the top which says 'int x = 0;' is what's called a variable declaration. It's saying that a variable called x will be an integer. If that wasn't there it wouldn't know what x was.
When you see // it means a comment, something the program doesn't use as it's code.
Another example would be:
// Hello Luc

[/size]First test with magnet as rotor. Without current limitation and magnet rotor the device consumes exactly 1 Amp at 3.50 Volts.Fr. Premier test avec aimant comme rotor. Sans limitation de courant et rotor magnétique, l'appareil consomme exactement 1 ampère à 3,50 volts.

Hi Luc, very nice demonstration.

You need to change the line that says:

x=5; //total loop delay is 20*x = 100ms. f=10Hz

You can change it to any of the the lines below:
x=1;  // x=1ms, loop delay is 20ms, results in 50Hz loop speed, or 1/3*50Hz magnet spin speed
x=2;  // x=2ms, loop delay is 40ms, results in 25Hz loop speed, or 1/3*25Hz magnet spin speed
x=3;  // x=3ms, loop delay is 60ms, results in 16.66Hz loop speed, or 1/3*16.66Hz magnet spin speed
x=4;  // x=4ms, loop delay is 80ms, results in 12.5Hz loop speed, or 1/3*12.5Hz magnet spin speed
x=5;  // x=5ms,loop delay is 100ms, results in 10Hz loop speed, or 1/3*10Hz magnet spin speed
x=10;  // x=10ms, loop delay is 200ms results in 5Hz loop speed, or 1/3*5Hz magnet spin speed
x=20;  // x=20ms, loop delay is 400ms results in 2.5Hz loop speed, or 1/3*2.5Hz magnet spin speed
x=25;  // x=25ms, loop delay is 500ms results in 2Hz loop speed, or 1/3*2Hz magnet spin speed
x=50;  // x=50ms, loop delay is 1000ms results in 1Hz loop speed, or 1/3*1Hz magnet spin speed

I note that it takes three times looping to go around the stator one time, so the magnet speed is 1/3 of the loop speed. Currently the loop speed is set (x=5) at 10Hz, so your magnet is spinning at 1/3*10Hz=3.33Hz.

Thanks

I changed line   x=5; //total loop delay is 20*x = 100ms. f=10Hz   to   x=50; //total loop delay is 20*x = 100ms. f=10Hz   and got an upload error!

What next?

Thanks for your help

Luc, check the serial port settings in your laptop Arduino program (the program you upload the sketch with). Most likely the wrong serial port is selected so it can't talk to the Arduino. Also make sure the correct Arduino is selected: should be the 2560 which is the board you are using.
