Peter Peregrinus Magnet Motor AD 1269

[Chipper]

Has anyone replicated this motor? Or do you know of anyone who has?

I keep seeing strange interpretations of his statements, and drawings that are way off of the mark of his original.

I am interested in seeing if anyone has done exactly what he has done.

 It is a perpetual motion design that could be up graded by using three arms insted of just one. It is worth playing with.

Well thanks for that. But I am really interested in getting his original machine to work. I have tried a few crude interpretations myself, and darn it all, I can't get it to work.

It seems to me that the drawing you posted, amongst others, isn't quite attuned to what he wrote. It appears that something is amiss. But in order to do exactly what he said, or possibly drew, requires quite a bit of effort. I would have to put some lodestones on the lapidary machine in my garage, then I would have to hammer out a bunch of silver capsules etc... Of which I am willing to do, provided I understand exactly what it is he did.

For instance, here is a fine example (but still wrong) of an approach.

The thing I have grief with about this one, is that the guy put the ball to the inside of the teeth, instead of to the outside of the teeth as referred to in the drawing and the writings.

It also appears that Peregrinus's model is exceptionally well balanced, between magnetic strength and weight of wheel together with the ball. I suspect that if I get it working, then it will be so well balanced, that I won't be able to get any usefull energy out of it. At least, according to how I interpret his writings and his drawings.

Things to consider.
1. He wrote his original letter in "Antiquated French". (implies errors into modern english)
2. Most translations available nowadays seem to be based on other peoples interpretations.
3. The drawing may not even be his original one.
4. Are the translators even knowledgeable enough about magnetism, to make appropriate translations?

At any rate, if someone has built exactly what is he described, working or not, I would like to see it. This would help me in my endeavor to do this wheel the way Peregrinus did it. I will be putting a lot of effort into this, so it would be nice if it didn't take me a year to do it.

Chipper, the picture does not match what is said and who is to say what is said is even true.

The more I think about it, the more I find wrong with it. The poles do not matter but yet it is said that one is used to attract and the other to repell but he is said to be using nails for the teeth. The poles have an eaqual attraction to steel and niether has a repelling affect on steel unless the nails are magnetized. Now if the nails were magnetized, which would happen after being subjected to a magnetic field, then what is stated as far as the poles are concerned would happen.
The picture shows a pole to be aligned with the teeth unlike what is stated about the need to be slightly angled.
The more I think about it, the more I find this not to be able to work. At least not as shown or stated.
If he built one that worked, we are not being supplied with the right information. It is interesting that silver or brass is being mentioned as an option for the weight where as the other parts are requesting the use of silver without giving an option for another metal like brass. I haven't played with silver, has anyone else? If so, did you find there to be some sort of differnce with it then any other metal when introduced to a magnet field?

Ya, now we are seeing eye to eye. I was having problems with the statement about constant repel and attraction taking place by only Iron. I really think Peregrinus knew better than that. After all, this guy came up with the basics of North and South, and designed compasses and all. This implies that something stinks in Denmark - as the old saying goes.

I sure wish I could get my hands on the original writings. Then perhaps take a crack at translating it myself.

There is definately a lot wrong between what was stated and what was drawn, and or implied...

I want to repeat your request for Silver. Does anyone know if it provides perhaps stronger eddy currents than Copper or Brass?

Why would he encase the loadstone in a silver capsule, and also the wheel?
Could it be he had tested some fundamentals of some sort of eddy current effect?
