      42413db2       From: DGoncz@replikon.net              --00000000000097a51505f79d6ab4       Content-Type: text/plain; charset="UTF-8"              I'm sorry I'm having trouble replying to my own post and those of other       writers in this news group using Google groups.              My thinking tends toward rather divergent novel posts anyway which are       difficult to relate to previous posts so it's not a total loss of advantage.              Today I have a significant development to report in my efforts to construct       a homopolar bicycle hub suitable for deceleration, theft resistance,       potential energy capture, and limited maneuvering assistance such as       driving the outside wheel in a very sharp turn on tough terrain, and       backing a tricycle up which is a feature that almost no tricycles have and       I mean human power tricycles here human electric hybrid tricycles.              So that said the homopolar makes use of the generator term in the faradays       law I stated in my other post on Maxwell's equations and faradays law. The       generator term is the positive term in the sum for e the electric motive       force. The alternator term is the negative term in that sum.              Well I've been tinkering with a small machine tool using a plastic chuck       called the unimant one. I've owned one since 1987. I've gripped a small       ring magnet made of neodymium iron boron alloy in the three jaw chuck on my       machines tiny headstock which is separable from the rest of the machinery.       Then what happened that is the development is this:              I had been toying with the idea of using a plastic core armature to measure       voltage induced by spinning the magnet rapidly with the driver motor from       the unimat. I gave up that idea. I ordered an inductor stock from Digi key       and it has a ferret core which is fairly strongly attracted by the magnet       on the chuck.              Well what happened today is I realized that if I insert plastic sheet or       washers between the magnet and the ferrite inductor I can establish a       uniform gap with variable friction and explore and plot and that is the       crucial part of many scientific and diverse, plot out the relationship       between the gap and a limiting current plotted on the y dependent axis       which would be the current at which the things stops being stalled assuming       that I can get any motion at all and that the heat does not melt the       plastic.              So I really wanted to share this with you all in case I need one has       explored homopolar motors in the physics lab. One vendor and I believe they       are in Czechoslovakia provides a homopolar motor disproof kit which       establishes that no EMF is generated even when the magnets rotate. I don't       have that kit so I can't report on the null result.              A fully developed homopolar bicycle hub motor would have North Pole facing       North Pole with a gap between, and an armature wound with a toroidal form       having some turns of wire, the core of the armature being a soft magnetic       material. Other components made of soft magnetic material would complete       the magnetic circuit and ferrofluid can be added to increase that       completion effect. In I am nowhere near there.              But I am making progress and I do like to report progress.                     Douglas goncz       Replikon Research              --00000000000097a51505f79d6ab4       Content-Type: text/html; charset="UTF-8"       Content-Transfer-Encoding: quoted-printable               |
