The Robert Adams Pulse Motor Design Review

I am considering purchasing an easypic6 development board and setting up a motor configuration similar to yours. Were I to forge ahead with this, would it be reasonable to expect that I could load your hex file into a chip of like specification? Not sure I am up to assembler programming but I have done a bit of C from long ago.

Your comments and advice on this would be appreciated :-)

Kind regards, nodrog.

Thank you so much for your Reply
I have been so busy working on my motor I haven't been on the forum for a while

I have some very impressive results I am eager to share.

I will give you any information you need I have anew PDF I have created about all of the PIC system

If you need the Hex file more than happy to email it to you
cheers

Hi Rod,

Thanks you for showing the schematics and the scope shots. Would like to ask the scope settings both on horizontally (TIME/DIV) and on vertically (Volt/DIV)?
It would be more informative.
You indicate PVN012AP photovoltaic relay now for battery separation during the drive cycle and earlier you wrote using a PR32MA11NTZF Solid State relay. The first one seems a bit slower device than the second one, is it still good for the job?

Have you already have some measurement results (input vs output) with this setup you show?

Thank you
Gyula

Pulsing

Hi Rod,

Excellent work!

However I am confused with the scope shot, no offence... but is it inverted?

Which way are the pulses going? Is TP1 On or off?

good question?

The pulse goes low to turn on the device because it is referenced to ground
across the transistor.

if you need a photo I will make one later

Nope, thats fine. I was trying to remember what you had said about the cap switch out not being on when the coil drive was on... but had not allowed for inverted logic, lol

On <http://www.overunity.com/index.php?topic=10398.new#new> message #400 I have posted a coil shorting jpg of 8 shorts at peak sine wave.

I mention this as the computer might be a hold up for many (me too) and my circuits could be adapted to run the Adam without computer control... just using pots adjust the pulse width and number of pwm pulses. Also just using two matched (same number) N channel fets for top and bottom switching.Any interest let me know... I'm in the middle of a bunch of things at the moment so it won't be instant. Didn't post here as could be OT.

Rod, now if you had been using the arduino uno... LOL, love to get started on that one....

[coss]

hello
this system have COP>1?

[eternalightwithin]

Yes it does. >>>> COP1 Go and build it. You will get much satisfaction

This thread is simply EXCELLENT. I am getting into it too.

Today I cut an MFD board to 200mm circle and used a motor from and old VCR as a bearings (excellent btw).

I ordered some coils from Rod so that I don't have to fuzz with wrong resistance neither inductance. I am trying to replicate Rod's replication.

In the past I did play with Adams motor with great "success". I got it to run in incredible little current and voltage and really cold, sometimes 5 degrees Celsius below room temperature using a digital laser meter. Unfortunately at the time I did not know how to use or program a PIC micro-controller neither new much about electronics and neither about what that really meant.

Today things are different. I know a lot more about electronics and what it really means and know to program a PIC micro-controller AND I have all I need to make it happen. Back in business again!

One thing I have noticed is that Rod is ONLY using one of the sides of the sine wave induced by the magnet passing by, Imagine when we start using BOTH sides??!!!!

Rod, THANK you man, let's make this OU happen for all for good.

Fausto.

Hi Rod,

I am keen to build your controller and wish to ask if I may get a copy of your
code for the PIC.

Kindest Regards, Penno
