showing a ruler and magnets.

Mylow just barely posted a video showing the rotor and stator magnets next to a Data Scan Ruler.
http://www.youtube.com/watch?v=xeijLKkuj_c

It looks like the rotor magnets are metric.

2 cm long x 1 cm x 1 cm, slightly tapered in the inside of the channel.

The stator magnets (he uses only one in his motor) are not rectangular but arced.  It looks like they are 1-1/32 inch long, 55/64 inches wide, ~5/8 from the base to the top of the arc, and ~1/2 inch to the bottom of the arc from the base (oriented like an up-side-down U).

In other news, Mylow phoned me this evening to say that the stator magnet has now diminished in magnetism to the point that the motor is no longer turning.

He stopped by the place he goes to get the stator magnet remagnetized this afternoon, to get permission to give out their name and address.  The preferred that he not do that since they are doing this as a favor to him, and they only want to receive commercial orders, but under those conditions, they may still allow him to give out the info.  They also told him (paraphrasing), "We can't keep remagnetizing your magnet for you.  It costs us a lot of money to run that machine and to maintain the hydrogen both."  They've been giving him a break on the price they've been charging him.  I encouraged him to let them know what he is doing, to see his videos, to inspire them to continue to help him out and be part of history in the making.

He said the alnico magnets in the rotor don't seem to be losing their magnetism at all.  Just the iron stator magnets.  He's looking to replace the iron stator magnet with something else that doesn't demagnetize so easily.

Once it's running again, he's pondering maybe taking this to the media.

I should mention that Milow also posted a video showing a review of his drawings from when he was in highschool back in the 1980s. Shows some nice-looking drawings he made, including of how the Johnson motor could be integrated into an engine block of a vehicle.

He was a pretty good draftsman, especially considering that he never took any drafting classes.

This ones way too big for MyLow but shouldn't demagnetize.  Could be killer on a larger setup.  HJ made his stator magnets from 12 smaller sections.

Ask him if he could get the company that magnetizes his magnet to map the gauss on one of the rotor magnets. Such would go a long way with all of this.

Howard Johnson: Secret World of Magnets

I just uploaded a 45 page .pdf by Howard Johnson (2.5 MB)

It discusses magnetic gates, vortices within a magnet, details of his 'banana' curved/cupped magnets etc.

Rotor speed seems proportional to the stator mag's strength. It slows down as the iron mag deteriorates.
I wonder if he could use a couple of strong Neo's on a steel bar with the 'right' shape & how long they would last.

Better yet, remove the magnets from a few old hard drives and stick them together.

He only needs two NdFeB magnets to remagnetize alnico and hard iron magnets. Place the south end of the NdFeB on one pole of the iron PM, and the north end of the other NdFeB on the other pole of the iron PM. For best results, leave it like that for at least a few minutes.

This idea about about expensive equipment to remagnetize alnico & iron PM's doesn't make sense to me because they have extremely low coercivity, which is the reason why they're demagnetizing so easily. In the video it's very clear the PM's internal alignments are flexing & changing during each revolution. What do you expect from such PM's.

I've remagnetized all kinds of PM's countless times just by using NdFeB. No big deal.

I have used such myself. great for them old crank winds from old telephones.

lostcauses10, I don’t buy this “Yea I can see why the guy would run”. As usual, it is him and the likes of him I already mentioned in my previous post who are the real problem, not anyone else. Let’s not be so nice to people who aren’t at all nice to us. C’mon.

So, let’s put the money where the mouth is. I’m willing to contribute for sending, if they are willing, X00013 or CLaNZeR or both to Chicago to see MYLOW121363’s machine in action. Is anybody willing to take me up on this offer? Let’s see how much the cost will be and where to send the money. No need to mention that both X00013 and CLaNZeR are prominent members of our community with proven record and if “death trets” are the concern they are the first to get such, way before MYLOW121363 so he shouldn’t pull the wool over our eyes with those “resived death trets". Both X00013 and ClaNZeR have access to machine shops and can then duplicate what they’ve seen with their own eyes, if they find it convincing enough to put the money and effort into this. Enough of these blind alleys those claimant are pushing the good people into. Undoubtedly, I’ll be willing, if it’s OK, to accompany them at my expense which by no means is a condition for my contributing to their travel. How’s that?
