Working Magnetic Motor on you tube??

[Rosphere]

Sean's setup is pretty nice, but when it gets down to the wire and you want to adjust things more precisely, loosening and tightening the stator mags and moving around won't give the best control, even though it is flexible. The design I have in mind would be very similar to what Sean has, but only I would use screw-adjustable stator mountings so that I could not only precisely move the stators (both circumferentially and radially), but I could make these adjustments while the motor is running. That way we can quickly fine tune it and see what positions work and which don't...

Good idea, Jason.  You know, the base of these things make great sounding boards.  Even in the videos we can hear the acceleration or deceleration of the device.  We hardly need the tachometer, but it is good to have.  Adjusting on the fly is a great way to find the optimum distances and angles.  However, as a metastable FE device, I fear that we may need more investment than this to keep it going.

What I mean is that we may need to invest in, or borrow, some high speed cameras.  This auto synchronization of stator angles without need of any sort of gearing is where, I believe, the magic and metastability lie.  It is the only thing that makes this design unique and promising.  I wonder what the stators are doing with respect to the rotor magnets during an acceleration phase.  It would be nice to be able to record real time data of the positions of the rotor and stators.  Now that I think of it, we would not need the camera if we had good, synchronized position/time data.

Let us say that we have 8 magnets on the rotor, as with he current design.  I want to know at what angle the driving stator makes at exactly those 8 positions when the rotor is accelerating, decelerating, and gradually loaded to control an acceleration run up.  This way we can both understand more about exactly how this design works and start to design control mechanisms to accompany the PTO, so that we do not kill the golden goose when we want to tap some power.  Blue_energy had some ideas about how to do this in an earlier post.

...off to work now.

Sorry if that comment came across as negative, I just think it hillarious that when you go through Al's material and read that an alignment difference in millimeters between the rotating stators and the rotor made the device "work as shown," that a device that does not resemble the original is being used to discount it. Al's device may very well be fake, or achieving it's rotation as a result of high EMF in his basement, but until someone builds a device exactly like the original, no one can claim whether it works or doesn't.

The Zero Fossil Fuels guy didnt even atempt to make a similar device. Why dont I just put a stuffed duck on a turntable (with a magnet in its mouth for good measure) to disprove Al's video!!   

Let's focus on more constructive comments rather that flaming others.
We might need them for future topics.

Yep, like the "Redneck OU channel"!  Surely if ZPE wants to have his own mythbusters channel (and not the redneck mythbusters channel) he's gotta do better than ferrite magnets & superglue where the spec required neo's, fairly tight tolerances, tested air gaps, AND the alloy dampers.  Sorry, but flaming that particular video is nothing but mandatory - I'd expect nothing less.

edit: or perhaps I've overlooked the attempt at comedy?

Good idea, Jason.  You know, the base of these things make great sounding boards.  Even in the videos we can hear the acceleration or deceleration of the device.  We hardly need the tachometer, but it is good to have.

You can make a poor man's tach using your sound card, an audio transformer and a CdS photocell (or phototransistor only, no transformer).  Radio Shack has the parts:

# Audio Transformer (8:1000) Radio Shack (http://www.radioshack.com/product/index.jsp?productId=2103254 Part# 273-1380)
# CdS Photoresistor Radio Shack (http://www.radioshack.com/product/index.jsp?productId=2062590 Part# 276-1657)

Here is the circuit:



You can run one of these circuits on each the left and right channel to monitor the RPMs on both pieces of equipment.  The output is recorded as a .wav file and you can either use Sonic Visualizer (www.sonicvisualizer.org) or some simple .wav file processing to get the RPMs back out into useful data.

Hello fellow seekers.
Got my magnets today 14th ordered from KJMagnetics. I'm in Sweden. Orderdate was January 5th.

Been following the developments since it was posted on PESwiki. Was very convinced to attempt make a duplicate....now undecided on the matter to make a duplicate or not, as many competent people seem to be on it. Everybody is busy so am I .

Does it strike anyone as odd that no other video of a running machine has been released after the initial one ?
With the thirst of information out there - and the expressed intent to make this Open Source - why no more videos of running machines ?

I guess we all will know within the next 7 days.
