These are test results reported by JLN, where's the similarity?

"When the LOAD IS CONNECTED the RPM speed is DOUBLED and the INPUT POWER DROPS dramatically".

Here's a picture of his monopole rotor:

I think that you will find that if you alternate the magnets you will get better performance.

JLN garnishes 2.3 watts in BEMF from his twin power coils. Does moving this current generate a magnetic field inside the coils that slows the current speed? I believe this is the common denominator for "Lenz Reversal".

FR2-5-2RS Full Ceramic Flanged Bearing 1/8"x5/16"x9/64" inch ZrO2
 
Price: $173.49

Magnet ring.

Dimensions: 1" od x 1/4" id x 1" thick
Tolerances: ±0.004" x ±0.004" x ±0.004"
Material: NdFeB, Grade N42
Plating/Coating: Ni-Cu-Ni (Nickel)
Magnetization Direction: Diametrical
Weight: 3.19 oz. (90.5 g)
Pull Force, Case 1: 40.44 lbs
Pull Force, Case 2: 49.01 lbs
Surface Field: 6909 Gauss
Brmax: 13,200 Gauss
BHmax: 42 MGOe

These rings are diametrically magnetized, which means they are magnetized perpendicular to the axis of the hole. The poles are located on opposite sides of the circular faces. They can be placed on a shaft to work with sensors or to generate electricity.

2 ceramic bearings  $346.98. One 1" neo tube  $22.77 Total cost:  $369.75

These bearings are a Little over sized. Sanding the bore hole just a tiny amount will allow these ceramic bearings to pressure fit just right. A brass rod can sand down just enough also to squeeze through the 1/8" ID bearing hole.

R2-5-2RS Full Ceramic Bearing 1/8"x5/16"x9/64" inch ZrO2 Bearings
 
Price: $46.88

This is the same bearing without the flange: Total cost for the 2 bearings and the 1" tube magnet $116.53

Here's the link:

http://www.vxb.com/page/bearings/CTGY/1-8inch

Here's the link for the tube magnet:

http://www.kjmagnetics.com/products.asp?cat=16

This small investment of $116.53 will put in the Hyper-Sonic RPM speed range. Don't neglect the "PVC coupling" safty housing!

The trick to mounting these bearings is First: Avoid glue!

Just sand each end of the 1/8" brass axle, and leave a thicker portion in the center for the bearings to squeeze onto. The magnet was pre-sanded to squeeze fit the OD and it all pressure fits. When your're ready the axle pushes through one side of the PVC coupling, the magnet slides on then one bearing, then the axle pushes through the other side to slde the other bearing on then it all press fits in the center. A bit of craftsmanship required. You won't regret it. A tiny push rollllllllls on seemingly forever!

A small air core series bifilar power coil, a Reed switch and a DPDT throw switch and you'll be in for the thrill of a life time with the "Hyper Speed Burst"!

Good luck sanding the I.D. of those bearings as that material is harder than the material used on your sandpaper.  You could use specialized diamond paper, but it is very expensive.  A properly sized diamond reamer would be the most cost-effective way to do this.

@Pirate88179,

The OD of the bearing is 5/16". The ID of the magnet tube is 1/4" that means the bore hole in the magnet needs to be enlarged by approximetely 1/32" and it's the magnet not the bearing I'm refering to. Sorry if I confused you. It might help to drill it out. Same goes for the bearing ID of 1/8". Assuming the brass axle rod is also 1/8", the brass rod needs to be be sanded, not the bearing. I would put tape at the ends where the magnet lines up and use a block to butt the rod up against then attach an electric drill to rotate it in a sandpaper sandwich. That would leave a full 1/8" thick section the length of the tube magnet in the center of the brass axle. Now the ends of that might need a tiny reduction, because lateral pressure on those bearings is potentially destructive. Any pressure needs to be applied to the base or the top of the bearing casing, depending on where the squeeze joint is. The flanged bearing might be safe to glue.

Just the vapors alone from some kinds of glue is enough to degrade the perfection of the precision ceramic balls. Once securely mounted, these kinds of ceramic bearings have extended longevity.

Ah, I see...never mind.  It is entirely possible that it was I that misunderstood you.  Ceramic bearings are great, and there are, of course, various grades.  I have found that the ones sold for skate boards and roller blades are actually pretty good and about 1/3 of the price you mentioned.  If yours is a higher precision than, that would make sense.

@Pirate88179,

The problem with the cheaper ones is that the ceramic ball bearings are set in stainless steel casings and all the stainless steel is unfortunatly magnetic. I just recieved two messages from manufacturers today confirming this. I believe that the presence of this material close to the magnet rotor will create drag and eddy currents and slow the rotor down. Lidmotor uses them at the ends of an extended axle with a high degree of satisfaction, but for internal magnet bearings I'm certain that the "All Ceramics" are far superior.

Here's the answer I got for the one pictured below:

A seller answered your question, "is the stainless steel non-magnetic?" about 1/8 x 1/4" Flanged Ceramic Miniature Ball.... 

Essam answered:

 "Hello,

"All of our Stainless steal has magnetic in it".

Thank you"

@Pirate88179,

A carbon fiber axle would help mitigate the effects of the magnetic stainless Steel. The advantage is that they would stick to the sides of the magnet. I think they're worth a try for the Price. There'd still be a homopolar vortex generated, but who knows how much it would hurt?

Here's a set of 4 from Amazon like the one pictured above for $35.03 plus free shipping!

OK, maybe I can help with this as we were in on the design and creation of ceramic bearings long ago.  All, not most, but ALL of the benefits of making/using a "ceramic" bearing go to hell if you use a metal race.  Not just for your experiments, but, think about this....-you have this very hard material and it is very wear resistant and chemical resistant, and you surround the contact for this material using a much softer material......what you have is crap!

In other words...(I also worked on this project for GM)  you have piston rings made from ceramic which is good for wear...BUT, the mating surface of your cylinders is aluminum...(or even steel) ok, do the math.  No benefits at all, and....even faster wear.

Who the hell makes bearings like this?  The ones I looked at from skateboards "looked" like total ceramic, but...I have never purchased any and if they involve steel then...it is crap.

Here's a DPDT schematic and picture of a blade switch: #1 connects directly to #2. #3 connects to the positive terminal of the battery and #4 to the start wire of the bifilar. #5 connects to the positve side of the Reed switch and #6 the negative side of the Reed switch. The end wire of the bifilar connects to the negative pole of the battery.

Once the blade switch shorts the coil directly to the battery, the coil turns into a D.C. electro-magnet. Current draw becomes limited after that by the standard formula of voltage divided by resistance, I=V/R. Any rotor acceleration followed by the direct connection would necessarily defy the second law of thermodynamics, and would serve as unconditional proof of an overunity circumstance.

This test, if successful, would catagorically confirm "Lenz Reversal" as an overunity effect once and for all and not a "Zero Sum" mechanism as our "Cynics" falsely maintain.
