BLDC PWM senseless motor controller manually Operating

Other Hardware Motors, Mechanics, Power and CNC
1

a Very warm greeting to all.

As a very NEW researcher in magnetic & frequency energy, with very little electronic board developing experience, I need the help of people who KNOWS in the Arduino Forum.

Can someone please help develope a BLDC PWM sensless Motor Controller that I can change all input manually for research purposes.

What I need is a PCBoard combination of the motor power driver & the Frequency Driver with all protections ie. BEMF, current and what is needed for protection on the board.

Also what will be a winner with the LCD monitor inluded with all of the INPUTS:

  1. V - A - Freq - RPM - Heat in Celcius

OUTPUT:

  1. V - A - Freq - Heat in Celcius

The input power 200 - 240VAC rectified to DC PWM Power driver and the volts VARIABLE from 0V - 240VDC with the LCD knobs changeable in 12VDC intervals and at least 10A circuitry with protection build in.

The Freq board combined to the power driver where the Duty Cycle & the Frequencies is variable seperately not effecting each other in the settings from 1% - 99%.

The Frequency settings from 1Hz - 16Mhz with 10Hz interchangeable settings for certain
range of frequencies. (Mega 2560 & Uno Ref 3).. Maybe the coding will control the manual settings.... I am not sure with a lack of knowledge.

This Bridge High Power High Torque Power driver must be controlled either by the Arduino Mega 2560 and/or Uno Ref 3, with a JUMPER setting on the Power Board to change the board output settings from single phase to 3 phase outputs and visa versa.

I presume that the only difference will be the coding and pin relationships to each other of the Arduino boards.

At last but not the least, is all the connections diagram of the Combined Power Driver & Freg Driver board onto the Arduino Mega 2560 and/or Uno ref 3

Attached link with more details of one of these drivers and circuit.

Hope you people out there can support and help me with this research project.

Looking forward to hear from anybody who are prepare to help.

I will gratefully accept circuit diagrams in Gerber file for manufacturing.

Warm Greetings & Blessings from out the Lovely South Africa.

Gert.

How much are you paying?

That is a relatively high power motor. But it is probably within the range of electric bikes. I would start with an off-the-shelf bike controller.

240V is high voltage. That's IGBT IPM territory perhaps. Opto isolation for gate drive is a really good idea (standard opto isolators are no good for this, high speed ones are needed).

Why the high voltage? I'd simply avoid the risks and go for low voltage if possible, saves cost, development
time, and fewer safety precautions are needed (but note that high power has its own safety issues, high
current failures involve big sparks, exploding semiconductor devices, overheating components).

Thanks for the replies so far.

The reason for the high volts as well as a current is for research purposes in the magnetic and frequency field.

Only the supply or input wil be AC power 220 rectify to DC and variable from 12VDC - 220VDC for research purposes.

So must the duty cycle & frequencies been variable controlled with the one not effecting the other, though also varriable from 1Hz say to 16MHz as what the Arduino can allow.

IGBT's will be used for the power drive that can handle high currents.

The coding not important at this stage as the Power Driver & Combined Frequency Driver Board and all settings that can manually be operating the most important.

Can you explain this further, I don't see how voltage is relevant.

It's not practical to make a driver for a range such as you are describing. There are very different parts requirements for low vs high voltage or current. Motor drivers will be designed for a range suitable for the motors they are intended to drive.

It sounds like you need to break it down into a few parts. It sounds like you want to combine a bench top power supply with a motor driver that can handle a huge voltage range. I would keep the two separate.

The circuit in the link you posted is a low voltage and low current demonstration. Starting with low voltage will teach you all about the principles of motor control without the chance of electrocution.

Do you understand 3-phase PWM? "1Hz to 16MHz" is completely out there as far as I can see, you'll be looking at something like 4 to 40kHz as a plausible range for PWM into a motor.

There are other ways that PWM to drive a bridge too, like space-vector modulation and hysteresis (bang-bang)
control.

There are microcontrollers with much better support for generating 3-phase PWM signals and more CPU
grunt for running high speed control loops. The Arduino isn't a specialist in these areas at all

OK!

Let me explain.

I successfully build a Magnet Motor and got the breakthrough om 19 February 2016 already.
With a 700W input and a output very close to 3KW just on the rotor coil combination. No generator coils implimented yet as the problem I did experienced with this model, was the quick overheating of the driver coils core.

  1. With further research for the last two years, I also made two very ADVANCED discoveries how to cool the system down very quickly and keep it cool with frequencies........ just amazing how this discovering works.

With frequencies input of in between 45KHz - 50KHz the rotor runs smoother and softer with bright light shining like spotlights.
The output coils rewind with the same driver coil with the power output to the lights

When the ouput light was disconnected, the rotor runs down in idle mode without any change in any settings.
When the lights were connected again, the rotor speed increases to normal RPM as setted, and the lights brightens up again like spotlights.

  1. I also make the breakthrough to run a generator coil in 3 phase loop with PWM frequencies put through the 3 phase generator coil as well.
    An output connection that increases the speed of the rotor instead, and also increase the output power to the lights connected to the output coil, where its brightness became like spotlights instead.

With an increase in frequencies to the driver and generator output coil, I made the sweetspot where the whole system ran into negative energy (AC Electricity) ie. outpunt current draw of 0.62A go into -0.62A instead without any change in the speed of the rotor or the spotlight brightness of the lights.

  1. Thus concluded that FREQUENCIES is the ULTIMATE for resonate power in FREE ENERGY devices.

CONCLUSION:

With my poor experience in building circuit boards combined with the frequencies driver board, I lost plenty boards burnt by either over current or spikes from BEMF.

To further my research and experiments in this field, I need the help from somebody who may assist in the developing of the combined power driver & frequency board for further research and developement.

If I make use of a VFD with 220VAC input which input is controlable, with a Arduino PWM system board connected to the VFD, with variable Duty Cycle and Frequencies not effecting each other in the process, whereby I may control all inputs manually, say from 1Hz - 16MHz as per Arduino Mega 2560, as well as the duty cycle from 1% - 99%, the results may also bring us OUT of the suppressed secrets of free energy.

Is there anybody who are prepare to sponsor me by the developing of such frequency driver board for use with Arduino and the 3 phase output VFD with coding to run the system manually for the research and testing purposes?

I will appreciate your replies.

Regards.
Gert

I have thought that there is somebody out there who will give help, but it seems that there is no interest at all. Can admin please delete this post. Money greed plays the biggest part in life.
Regret.

As there is really no interest in personal support in my research & development, I am busy learning the VERY HARD WAY to develope my project.
All hardware in this research works perfectly, but still suffering to get the Arduino coding as I want it to do the proper work.

If money and greed is and was not the main factor in life, life would have been a pleasure with confidence in most people.

I'm with Dave Jones on this one:EEVblog #708 - Free Energy Overunity is RUBBISH! - YouTube

[ In my experience some of the Free Energy proponents out there are perfect examples of greed by by cynically defrauding gullible people of there hard earned cash and deluding them - and some are self-deluded of course ]
