Shouldn't it be fully possible to use repelling forces without degaussing the magnets?

Let's say you have two magnets side by side vertically. Nort up and south down. These two magnets will repel each other without degaussing because the magnetic lines will allways be in parallell. However, if you twist the magnets 90 degrees in opposite direction, so north or south directly points into each other, you will have repelling with degaussing after a while. Isn't it so?

The more the electro magnets, the more it's starts to look like an ordinary pulse motor.

The big difference would be that this design is not decelerating between it's pulse coils. That would make quite a big difference I think.

Here are my thoughts on that.

View topic - constant velocity increase

Your solution is much better as my idea of adding large numbers of pulse coils. (as shown in the big pulse motor)

Maybe it's only me, but I'm quite sceptic to so called magnet motors with a lot of batteries ans wires all over the place...

Show me a video/evidence of a magnetmotor without any wires - at least no batteries

Stefan quotes Paul S. somewhere in the Steorn thread saying that because Steorn used repulsion in their model it would lead to a degaussing of the magnets and that his motor is running on attraction only. If it is indeed the case that the magnets can be demagnetized by applying repulsive magnetic forces, then  repulsing  the rotor away might demagnetize it and nearby stator magnets and lead to a loss of torque or function. That could be an important point to consider.

You missunderstand how magnets work and how they are used. And you haven't really grasped my FBDISSM yet.

1) Magnets in an ordinary electric motor is continuously working in both attraction and repel mode. Otherwise the ordinary motor
    wouldn't work any good. And the magnets never demagnetize when being both attracted and repelled, just as in my motor but
    with the difference that the repel mode is just applied for approx 4-7% of the loop time. The rest is pure attraction.
    So there is really nothing to consider regarding the risk of demagnetizing the magnets.

2) So far I have never encountered any repel setup using neodymium magnets that will demagnetize each other.
    I have read a lot about repel mode at this forum and others places as well, but nobody really knows if there is a risk of demagnetization.
    People are just guessing about this subject and it has started a rumor that repel mode will demagnetize neo magnets.
    But the truth is most likely that neos wont demagnetize in repel mode due to the fact that their demagnetization curve states that it
    takes about 1200KA/m to even get close to the risk of damaging the magnets. Just to clarify you should now that 1200KA/m is a many,
    many, many, many times stronger field than any neodymium magnet is capable of delivering. Like a 100 times stronger or more.
    Perhaps there is somekind of eddy current involved at repel motion that will heat the magnet & lower the threshold of the demagnetization curve.
    Just to find out about the risk of repel mode I have built a motor forcing 2 discs full of magnets in repel to interact in full motion at 1000 RPM.
    I will let this motor operate the discs for several month, perhaps a year, and then I'll know for sure if repel mode can cause demagnetization.

3) I repeat. The FBDISSM does not operate in repel mode, it's pure attraction. The small repel pulse will not affect the magnets at all.
    If it did affect them, then no other electrical motor of the whole entire world could work without getting demagnetized, and they dont.

Hi Honk,

Thanks for your patient explanation. This has cleared up a few missunderstandings.
As I am new to this field but fascinated by this split spiral motor concept there is lots to learn and relearn and very little in the sense of textbooks or prior art. Hence I am glad to be able to ask questions at this forum, hopefully contributing a little and not holding up or annoying anyone.javascript:void(0);
Your argument concerning demagnetization makes absolute  sense to me, especially in light of your ongoing twin magnet disc experiment. I did not think thought that the FBDISSM was operated in repel mode, I just assumed the repel pulse to be equal to the attraction pulse.

Cheers

Hey Honk,

You got a fascinating thing goin on here... I've got a couple of questions of course, and maybe an idea or two that might throw a monkey wrench into the mix

1. Would it help the situation if there were 2 of these motors stacked on a single shaft? I.E. Have the 2nd motor rotated a bit so that the sticky spots do not overlap. Would having a setup like this decrease the "stickyness" to the sticky spot?

2. Instead of using a normal N/S magnet in the rotor, could you potentially replace it with a Halbach array? I've been surfing this forum for a while now and I don't think i've seen anyone mention using an array as a rotor or a stator anywhere (correct me if i'm wrong - i've been gone a while). If i'm reading the info on Halbach array's correctly they are the closest thing we could get to a magnetic monopole...

3. Why use a stainless steel guide for the stator magnets? Will that not affect the magnetic field lines a little bit? I understand that the effect will be fairly minimal, but in researching magnetic shielding a bit I'd think that there would be some kind of affect. Perhaps a good quality plastic would be a better idea - I understand that it wouldn't be laser precise, but a good injection mould can do wonderful things

4. This is just a pure question for you Honk, because you sound like you really know your stuff Would a product like Giron (http://www.lessemf.com/mag-shld.html) be of any use in a motor like this? I.E. inserting it into the sticky spot to change if from a sticky spot to a coast spot. My understanding of magnetic shielding is very limited...

Thanks for the great work and honest and forthright replies Honk! I look forward to more details so we can all get to building one or 2... maybe 3...
