Electric Motor Secrets

By the use of this motor the pollution in the air can be stopped.I would use a small appliance motor I scrounged out of a vacuum or fan. Ten pounds is not that much just test out your gears or belts to be sure you don't over amp your motor. I would bet the motor from an old hand held drill or such would be small enough to hide well and strong enough to lift your ten pounds. Make sure you gear it down so the speed will not shoot anything into orbit when you open it.

Lindemann Rotary Attraction Motor from AC Motor

Hi All,

After following this thread, I completed (modified) a 1 PH AC Motor to Rotary Attraction motor. Here is the video:

YouTube - Rotary attraction motor from AC motor

I'm still using the stator winding of the original motor and drive the spinning with a reed switch. May be caused of the small wire stator winding, the speed and torque of this motor is not satisfied.

Newbie question about Peter's solenoid motor featured in the DVD ...

Hello.

I am learning so please excuse my ignorance.

Why are there four windings in the coil.

One is for power in.

One is to send the current caused from the collapsing magnetic field to charge a battery.

What are the other two used for please ?


Thanks.

Please guys, stay on topic. Those motors have nothing to do with Peters attraction motor concept.

Ok ... gone

Anyway this is the patent number for his motor:
5,514,923

Scott's Motor

Has anyone heard of or know if this motor ... I know this guy ... He built one of his early motors in my shop ... decades ago.
Nice to see he got a patent on it ... May 7, 1996 ... 5,514,923

The patent is moot as it is not an original idea. Here (attached) are just a few of the copyrighted drawings provided by Mr Bill Muller dated 1987. Let me add - WE discussed this motor at the Colorado Springs Symposium - Aug 1984.

field collapse directly used

Hi Everyone,

I truly believe that the following post is in the spirit of the 'electric motor secrets' discussion.
-------------------------------------------------------------------------
---because there is no longer a reluctance gradient. It is during this period of zero change in inductance that the energy on the coils is discharged, usually to be stored on a capacitor for later use.

Hi all,

About 15 years ago I selected a VR motor (variable reluctance motor) for an energy recovery project. What I proposed actually worked and rather well to my surprise. What I did:

Some VR's come with both the + and - coil wires freed and not common(ed) in anyway. A local surplus store had tons of these. What I did was hook the pole coils up in such a way (using diodes of course) that when an energized pole field collapsed, it dumped the energy into the next pole. So using one with 4 or 8 poles on the lams was optimum. The only 8 I found had a badly bent rotor so I used a 4. So basically windings #1 and #3 got energized when their times came and windings #2 and #4 received the collapsing field energy from their neighbors, #1 and #3 respectively. IOW: #1 gets energized, turns off, collapses and in turn energizes #2. #3 gets energized, turns off, collapses and in turn energizes #4. Now we're back at #1 and it repeats. Now a VR stepper usually has 3 or 5 pairs of windings but whatever it was, it had an even number of wires and it worked.

Stalling the rotor you could feel the torque upon energizing a coil set and then feel a second (but smaller) torque when de-energized. As you might have guessed it ran best a one speed because the collapse does occur at some rate so there was some timing sensitivity.

This only worked because VR motors are attraction motors thus having NO rotor polarity to contend with.

Thought I'd share,

Greg

Make a little 555 timer circuit and chop the LED front end of your optical commutator with a 50% duty-cycle and an ON-TIME equal to about 1.5 time divisions on your scope.

If you make the 555 timer circuit with a variable pot, you will be able to dial up the perfect chopping frequency to maximize the energy recovery. Once you know the right frequency, you can hardwire the circuit for those values.

THIS IS EXACTLY WHAT I NEED!!!

Idea officially stolen

So much great information in this thread... Applications in so many areas.

Price

Hi CyberXena,
I have seen that Proto Laminations site before, and I always wondered what the cost will be for such an attraction motor. Please let us know how much they quote. As far as I understand it they make actual laminations dies that stamp out the shapes rather then laser or flow jets. So I really wonder how expensive this service is.
Please keep us updated!

Thanks,
Steven

Anyway, I think that the V3.0 motor has a lot of potential if the power ON times are chopped so that they match the current rise time and if higher voltages are used. So far I have not encountered any problems with that design and if I had to make a new one, I would make it just like that again. The adjustable timing and duty cycle commutator works like a charm

Thanks for responding your project has inspired me to build one now. I will use a lamination house here to cut down on the work a bit.

Proto Laminations' Electromagnetic Web Site

I have to think about the rise time vs power on chop time issue some more to understand it well. I am considering using a microprocessor to adjust timing and maybe voltage issues - I have prototyped some control circuits for the Arduino system. Pehaps this will be useful to others in the future. A couple of questions, please excuse me , What voltage did you mean in the quote 12v? 24V or more? I have run my motors up to 20Volts so far. Another question does your cnc system use standard position codes? (g-code etc.?) Did your speed-to-torque converter work well? I was planning on using one myself to connect my motor to an axial flux generator I'm building. They have less torque requirements than PMA's. I have several of the PMAs (Wind blue and others). I started to build a two motor version of the one I posted on this board, but then decided to wait on your project to see the outcome. But Now it seems to be the time to go forward. Thanks again for your response.
I hope to be able to tap your expertise (as time allows )as the project goes on.

Hi cyberXena
Unfortunately I have not made any progress with the V3.0 motor at all, both motors are just sitting on the shelf and waiting some better days. I am busy on other things now. My problem is that my enthusiasm always jumps back and forth between different projects. Also I don't have a decent way to measure the mechanical power of the motor because it runs so fast and using Peters way I cannot get a decent data, also my flywheel is made out of acrylic and it melts at those speeds if I try to slow it down using friction from the leather belt. I think that in next month or so I will be able to get access to a decent dynamometer and then I will tests both attraction motors and the Flynn motor that is currently consuming all my time. Anyway, I think that the V3.0 motor has a lot of potential if the power ON times are chopped so that they match the current rise time and if higher voltages are used. So far I have not encountered any problems with that design and if I had to make a new one, I would make it just like that again. The adjustable timing and duty cycle commutator works like a charm

final word on V3 motor? - torque?

Hi all,
It's been a while since my last post in this thread. I have nothing new to tell yet, because as Peter said, I am busy with other and not so interesting things right now. Anyway, I wanted to tell that last week I held a lecture about Bedini devices and Peters attraction motors at local particle physics institute. They organize seminars each month and many other enthusiasts like me visit those seminars. The main topics there is renewable energy. Anyway, I shared what I know and demonstrated my attraction motor. I used V2.0 motor to show the principles, I made everything so that I could put the inductive spikes to the front side capacitor using a switch when the motor was running. At 12v it rotated at about 3500RPM, was loud and consumed 2.4A of current. When I flipped the switch, the current consumption suddenly dropped to 1.4A, the motor became much quieter and the RPM's increased noticeably. That was a real eye opener for many of the people there, everyone was very interested. I will make a short video that demonstrated this, so I can promote this technology further and maybe someone with more free time and resources will be able to bring this thing to the next level.
Also just then I realized why this current waveform of V2.0 motor looks like it does:


This image shows the short current pulses that fill the whole 70 degree attraction window, they all are equal in duration, but nevertheless each next pulse gets shorter and shorter in amplitude. This is because already at air gaps of 0.13mm the varying core inductance trend starts to show itself and it gets even more obvious if the air gaps are even smaller, like this waveform with 0.08mm air gap:



All this need to be taken into account when building such motors. I should have realized this earlier. But what can you do, you never stop learning

I hope this helps someone.

I was wondering after following this whole thread and building two simple motors out of old series 1 motors. I was wondering what the final word was on the V3.0 motor? There seemed to be this issue with wave form and the torque.. are they resolved. I now have a machine shop and some resources to build one from scratch but I would like to know what the summary of this V3.0 design was...
Thanks

That waveform is more substantional than your explanation. Recently with Steorn I discovered some things and got an even deeper understanding of inductors. When I first saw your waveform I didn't think much of it but since I have some more knowledge now I want to adress it.

Yes as the rotor closes the gaps the inductance will be changing in realtime. But your waveform shows something even more amazing. In theory the rapidly changing inductance will create an asymptotic slope. Almost exactly the same as an RL current graph (you can show this by simple formulas). That is the rate of current rise will decrease the more the inductance is being changed. But this means that the slope should die off.

Yours is doing something very unusual on the other hand. Not only is it dieing off its slope is changing sign! Do you know what this means? The inductance has become negative during that short time period! This has some substantional implications. One of those is that your motor has been destroying energy . But if that negative inductance can be harnessed then an inductor will create energy just by hooking it to a battery. The current flow will be in opposite direction than a regular inductor thus charging it.

Thanks to your work I have gained some new knowledge.
