N52 Neo's 25mm x 4mm coils made by me till I got bored of turning took pictures but not as many as I wanted getting those pics off of the camera later on about 1 hour when I rebuild out of more robust parts will be gettting pre-wound coils
got some dodgy arduino's too here they are
they don't come up with a com port in the arduino IDE don't know how to make them work
any how the lack of photo's will be sorted in the next few days due to time constraints couln't get all done that I wanted, tut!

here is a few pictures on the screen in yellow reads RPM 525 machine vibrates a bit! pic1 and pic2 shows something unrelated theTL074 the mic, preamp and amp with a reference ground pic3 show me tinning a wire pic4 5 6 7working on the bar graph displays again unrelated pic8 is the display for the rpm meter pic9 shows an overview of the project pic10 shows the usb slots that I made along with the IR2110 H-bridge stuck to a piece of cardboard pic11 shows the backside of the maching pic12 the frontside pic13 shows the arduino that controls the electronic speed controller with a pot to control the speed pic14 another overview and finally the pic15 shows my paint drawing of the wheel and the magnets 1/3rd out of phase was going to do the AC readings from the coils today but run out of time on my session!

there is one coil that is just an untouched coil factory wound, It's at the bottom on the back I used ferite welding rods for the core the rest of the three coils are wound around bolts and the Neo's are doubled up so 8mm of magnet! on both sides of the wheel

so those R3 UNO's that I mentioned do not come up with a port number normally port 3 or port4 and when trying to upload the squarewave code to the nano it comes back as
avrdude: ser_open(): can't set com-state for "\\.\COM3"
An error occurred while uploading the sketch
does anyone know whats up?
this is the code I'm trying to use:
avrdude: ser_open(): can't set com-state for "\\.\COM3"

this is the code I'm trying to use:
C:
#include <TimerOne.h>
const int pwmPin1 = 9; // PWM output for signal 1
const int pwmPin2 = 10; // PWM output for signal 2
const long frequency = 50; // Frequency in Hz
const long period = 1000000 / frequency; // Period in microseconds
const long deadTime = 50; // Dead time in microseconds
void setup() {
pinMode(pwmPin1, OUTPUT);
pinMode(pwmPin2, OUTPUT);
// Initialize Timer1
Timer1.initialize(period);
// Set up PWM outputs with complementary signals and dead time
Timer1.pwm(pwmPin1, 0); // Initialize with 0% duty cycle
Timer1.setPwmDuty(pwmPin2, 0);
// Set up the ISR to control the PWM signals and add dead time
Timer1.attachInterrupt(updatePWM);
}
void updatePWM() {
static bool toggleState = false;
// First half of the period (signal 1 is HIGH, signal 2 is LOW)
if (!toggleState) {
Timer1.setPwmDuty(pwmPin1, 511); // 50% duty cycle for signal 1
delayMicroseconds(deadTime); // Dead time
Timer1.setPwmDuty(pwmPin2, 511); // 50% duty cycle for signal 2
}
// Second half of the period (signal 2 is HIGH, signal 1 is LOW)
else {
Timer1.setPwmDuty(pwmPin2, 511); // 50% duty cycle for signal 2
delayMicroseconds(deadTime); // Dead time
Timer1.setPwmDuty(pwmPin1, 511); // 50% duty cycle for signal 1
}
toggleState = !toggleState; // Toggle between signal 1 and signal 2
}
void loop() {
// No logic in the loop. PWM signals are handled in the ISR.
}you can see the capacitor bank in lots of the photo's!

awsome guy!! can you provide an example between to voltage sources please? I'm going for a session in less than an hour so if you can shed some light on how to get the arduino's working that would be great too! thank you
so I think this is right so far

so did not make readings because one part failed and have to wait for the super glue to go off before I run it again not risking running it till completly dry I measured the resistances though front top 13ohm front side 10ohm back bottom 59ohm and back side 54ohm and one voltage reading before it broke down was on the back bottom and it read 40.5vac this is at 550 rpm, so need to measure the ac from the other 3 when I get it back up and running! probs not today! also the arduinos are not playing ball so pretty pissed today nevermind!

It’s only a simulator.
Real world characteristics kick in.
Temperature, tolerances, resistance, inductance, capacitance,reactance. It all makes a difference.
Is a driving simulator the same as driving on the road?.

did you see this post I posted it like seconds before your comment?
look at this see what you recon. As you see it does not work can anybody render it to full working order? so the ac coils power the circuit I've provided both the schematics working one is "done_ski" and the one I want working is the "modelling machine with..."
