Cogging ...
As 1 pole draws near to a pole they resist each other ...
Two poles. One on the rotor (a magnet) and one in the stator (steel core). "Draws near to" = getting closer. "Resist each other" = repel or repulsion. What did I twist?
In his very FIRST line he says “two magnetic poles”. He is talking about electromagnetic poles one created by an electrical supply and the other induced by the approaching magnet in a coil.
Very first Google hit:
Is steel magnetic?
A: In general, steels are magnetic.
That has as much to do with what we are talking about as what you linked to. Magnetic pokes is what he said. Obviously they contain metal as well as a coil or you could not possibly build a motor or generator out of them. He said magnetic poles which is different than steel poles. Am I correct or incorrect?
You are incorrect. A magnetic pole in a motor or generator does not have to have a coil around it. Look up consequent pole. And besides his whole post was about cogging which is independent of coils.
You're guessing about what you think he meant. I am talking about what he wrote and posted and the common, scientific and technical definitions of the words and terms he used.
Shop class today
Jordan cut his Madmack parts out today to explore cogging.
We have the bearings, shaft, collars and now platform pieces.
We have the square magnets and the material to build adjuster.
After cancellation is performed we will sub out 1 pole with and iron
core with coil. If everything goes right we might be able to run this big
wheel with a tiny rubber band type belt using a miniature motor to
see how much the coil will put out.
3 battery discharge motor to a MadMack style generator rotor for my
son. Slow speeds, very safe and energy conservative. Don't quote me
but I think I saw the drive motor amps at about 50ma-75ma on 12vdc
coming from the 3 battery arrangement.
Mounting and placing the motor plus stainless shaft in the mail. Drilling
the hub and then placement of square magnets.
Put in many hours of work this week building. My ss shaft is here
and the one bearing for the top mount will be in soon. The mail
is stopped up bad, I ordered a bearing 3 weeks ago. The motor
to drive the wheel is mounted to my satisfaction and the upper
cross member is going well.
I can't believe all the hours I put in and it looks the same almost.
This really takes alot of time and I enjoy it.
one thing I need to do is take out a small segment to explain the
way I build. So many guys are not as well equipped plus have little
experience rigging.
Cutting tools for metal plate and plastic are important, then a welder
helps a bunch so I'll be showing my designs soon for the guys who
are wondering how to start something to make tests with.
Since magnets are very powerful at close range to metal cores it becomes
imperative that a rigid structure be formed, not as easy as it may seem.
