Howard Johnson Replication Tube Claim

[carbonc_cc]

I think this rotor should work.  Though it has a bit of friction and drag.

Now I just need to find a nice pizza pan to mount onto the rotor.

I spoke with Mylow this evening (~6:20 pm Mountain).

He's been looking all over for stator magnets.

I recommended that even though the ones I pointed out a couple of days might not be close enough of a match in his mind that he ought to go ahead and get them to give them a try.  There's a scientific pursuit here as well to find out what does and does not work, and to explore the ranges of operation.

Referring back to the test he did a couple of days ago in remagnetizing his iron stator magnet with neodymium magnets, he said, "the Neo magnets worked, but not like how I liked it."

A few days ago he went back to the place that had been remagnetizing his stator magnet and talked to the guy in charge, who was not at all inclined to help out with the project by continuing to remagnetize his stator magnet.  He said that the machine is very expensive to run and intended for paying commercial contracts.  It is used to magnetize magnets used in CNC lathes, to hold things in position.  He was dubious about what running that little magnet in his state-of-the-art machine might do to the equipment.  He did give a couple of referrals of others in the area who might be able to do this for Mylow, but when Mylow checked with the referred parties, they declined to help.

He's in process of documenting his re-assembly of the unit, taking video as he goes, and uploading them to YouTube.

In looking at the HJ motor photo some more, he said he noticed that HJ's stator magnet is higher than he has his.

He commented on CLaNZer's replication and commended him on the work he's doing.  He noted that the stator magnet is quite a departure, and he'll be interested to see if it works.

Mylow's goal for himself is to end up with a self-starter, so that he doesn't have to do anything with the rotor to get it to begin spinning other than to bring the stator into position.

@ sterlinga , you had me at "CNC",   sounds like the plant is producing mags for servo motors. Steppers use triangles, so servo motors it is, like as i RC cars that use servos, etc... Just wanna point that out, if you find the "standard" polarity for high quality servo motors you will have your FEMM info. Thanx 13

Note addition of permeability plate.

http://www.youtube.com/watch?v=_0adKZ7q1Qg - nearly dead magnets still have some weird movements

http://www.youtube.com/watch?v=GVwkb-5JVI0 - Video that shows the aluminum disk spinning and its flatness

http://www.youtube.com/watch?v=G6j3XsUoITY - rebuild of the magnet motor; placement of the first three magnets. Magnet bar used for spacing. Not exact, "okay".

http://www.youtube.com/watch?v=7lTl_Wvs0MY - permeability plate added to one set of seven equally-spaced rotor magnets, "just like Howard Johnson has in his motor".
CLaNZeR runs a wind-down test and shows his rotor magnet placement.

Or find a servo motor near the diameter mylow used, and you have your stator mag from the original vids, I'll c what i can dig up !


@ Clazer, Thnx
