i like your consept mine is a slightly diffrent design i never used the bearing to stop up and down play. I have been using mine for a few years now tho. Thanks for the wake up call need to move my project on, cant believe how close people are to the big break through
i can see how it stops the side to side play not sure how it would stop the up and down play and im still waiting for an ancer from my email about prices
I am not shure that I understand your description of the system. We have two or more magnets put together. The rotor is made of a conducting material such as copper. Copper is not magnetic (this is not entirely true since copper does contain some magnetism but generally not enough to make a real difference). Thus is not the rotor drawn to one side. Also the magnetic fields are balanced in a cunning way.
I hope this was an adequate anser to your question.
the magnet are diametic 180 segment 2 segment per side( total 4 segment)? other wise the metal conducting rotor would be drawn to the onside of the magnet
pleease clearify how the contor rortor stay center other wise?
You are absolutely spot on! This type of bearing actually benefits from having a large diameter. The bigger the better. This has to do with the surface area of the magnets that makes most of the important parameters increases by the square.
There are three different types of bearings. 1. The inner rotor bearing - as you would imagine a normal bearing. 2. Outer rotor, 3. Intermediate (Hollow shaft) with magnets on the inside as well as on the outside.
Can a bearing of this type be constructed which could have a large bore shaft of any size and keep the inside to outside diameter thickness at a minimum? I am looking to create a vortex tube and the shaft size needs to be rather large. The shaft would actaully be a tube casing with a ID of at least 6 inches.
No outside electrical input is needed to control the bearing.
As a matter of fact thnks to this the EDB is capable of handing extremely fast events transient events - lets say an impact with extremely short duration (explosion for instance).
A contact ball bearing would in such an event have had all the steel balls crushed and an active magnetic would not manage to send out control signals.
We will shortly post a simulation showing this remarkable feature.
For this specific bearing (there are two more - one with an outer rotor and one so called internmediate bearing) you mount it like you would with a traditional ball bearing. There are specific bearing housings for this purpose commercially available.
Fitting the shaft to the inner rotor can be made in several different ways. One is to heat up the rotor and chill the shaft. This in combination with the right tolerances will provide the needed function.
Many thanks for the compliments.

The genius project. I could see the PhDThesis about it, and presented is simply fantastic.

i would like to know if there needs to be any outside electrical input to sustain the high speed.

How can you fix the housing of the bearing to the machine?

So, where are your HED bearings available?
I would like to put a couple to the test.
