10 - Oscillating Stator Permanent Magnet Motor.

I believe the apparatus must be such that the timing has a much larger window, not nearly so critical. I'm cooking up something good for the next video. Stay tuned!

It was just a thought. You are doing great research here btw. Very interesting. Thanks.

Friction losses. Unavoidable. That's the problem. Only things I'm aware of approaching perpetual motion machine status are superconductivity, the orbital motion of planets, etc.

You deserve alot of credit,i have been thinking of tis same principle for years. I beleive part of your problem may be in the timing,must be just right. I beleive you have to get itjust at the point where push pull is properly seperated to become a rhythym and starts to pulsate. Also if your diameter was larger it would have more power. Hope my ideas help,will definetly follow your progress

It has also been suggested here to use a spring to achieve a more sinusoidal movement on the stator w/o modifying the bobbin raceway. I might give that a try too. It would be very easy to replace the linkage connecting the two arms with various length U-shaped pieces of coat hanger, even though I believe that would create just one sweet spot RPM.

Give me a day or two to lick my wounds (literally). I'll conduct the tests using the Dewalt drill that I injured myself with and a friction wheel in the chuck to spin the device up to a constant speed each time.

Cheers,
ZFF

You're right about one thing for sure - I do deflect the stator more at start-up but only because that's how I start it from a standing stop w/o spinning the wheel first. Once in motion the stator deflection remains fairly constant regardless of speed. At least that's how it feels. I think some high speed photography would be easiest to reveal what's going on.

What I'm doing mechanically is pretty much the same with one exception - The roller will be 3-4 times closer to the center of rotation, at the bobbin, so that the rotor magnets have a mechanical advantage over the stator. In your animation the roller is at a mechanical disadvantage.

That's already beed suggested. Thanks.

Okay. That's an idea. I've got an assortment of some stiff springs I might be able to try in place of the linkage connecting the upper and lower arm. Thanks.

why dont you attach a pencile to the bottom arm so you can use that as a scribe. That way when you move it by hand it wiil trace your exact movement on the cam

get a better heavier fly wheel that is really round.

[contd]Also, I guess there needs to be an offset. You need to take measurements before you make anything mechanical. Doing it using a relay to oscillate the arm and using a frequency generator to vary the amplitude/phase/frequency should be easiest IMO. Let me know if you need any help.

Did you try it without a load?
What I see is, you oscillate the arm more when the rotor is at rest and is starting up. (It swings more) and as it takes on speed you oscillate it less, but more quickly.
So there is a timing issue. [contd]

Hi ZFF
You can see the animation I made by clicking my name. (or paste youtube code:DAfqbx96GbQ.
Check the description for details. Hope it will be of use.
