Energy > Inexhaustible > Magnetic Motors > Bowman > Open Sourcing > Instructions > Specs > Non-magnetic materials Use non-magnetic materials for rotors and bodyYes, a lot of stuff has magnetic properties that can be overlooked in static modeling. Induction can set up after startup, and so on. This can be failure in a prototype free energy device that is working with new, or little understood processes. Believe it or not wood, and fiberglass can cause some problems as well as the non ferromagnetic metals. I use 316 SS and plastic that is non-fibrous even then the way we use the stuff is important. Keep the metal out of the path of the magnetic fields is law number one. Douglas Alt Materials

Would any of these have issues in terms of magnetic interference?
What is the price differential? Strength?
Hopefully we will be having centripetal forces to contend with.

Answer: I have researched issues of substances in effects of magnetic shielding and found that there are two categories of substances. Nonpermeable - wood, plastic and any other non-magnetic substance, these do not have any substantial effect on magnetic fields. Where Permeable substances such as steel act as a magnetic shield. So I don't think any plastic is going to make a difference. Question: What is the price differential? Strength? Answer: I have asked one of the major suppliers of plastics to give us information on other plastics that have properties very close to Delrin. Since they made a comment that there are cheaper replacements I think we will find one. Strength: At .5 inches of thichness I don't think we are going to have any problem with that for any plastic we choose. Question: Hopefully we will be having centripetal forces to contend with. Answer: True, we would hope that once optimised, that the RPM's will be fast enough to have to worry about that.. And potentially vibration from the magnet moving past each other causes side to side forces. Could start to really vibrate once we get up to speed.

Subject: [PES_BMM] Delrin - not available in Clear
is spelled "Delrin" and made by Dupont. In it's natural uncolored state, Delrin is opaque white. I had read that Doug would like us to make the engine clear for better demonstration. I am quoting from one of the sites I was on that says: Quote: If you did not find the Delrin® lot that you were looking for, we suggest that you check your requirements and maybe use one of the Nylatron/Nylon formulas. Delrin®- Acetal is a wonderful material but there are materials with many of the same qualities and are considerably less expensive. So, my question is, does Delrin have a property that we really need, or can we substitute it with another plastic that is available in clear so that we can produce a good clear machine? If we can use something else, then I will continue my search for a good supplier of a clear alternative. Return to
