Title: Big acceleration and deacceleration forces will make the motor very shaky..
Post by: hartiberlin on May 28, 2005, 06:55:55 PM
Bi Butch and all,
if you motor will work as thought, I wonder, how long it will last.
As there are many pretty big acceleration and deacceleration forces onto the rotors
and they will hit each other with a lot of force, I also wonder, if one rotor
will really always stick to the magnets and be loosened by the second hitting it.
I guess at higher speed the couldchange somehow.

Now I think we must find also a better way, that the rotors will not be
accelerated and deaccelerated in every cycle.

I think the MFT design from Dave Squire was a solution to this problem.
There the iron rotor was made of a pair of rotors so each single rotor
going into the magnet fluxgap was also pulled out by the second
one, being not yet fully in there.

In the MFT design we had always positive forces over one cycle
and there is no cogging as in Butch?s motor, but okay, the forces are also weaker.

Butch?s motor has the advantage that the foces can be made very big
and thus the torque will be immense.
The disadvantage is the permanent acceleration and deacceleration of the rotors
that will wear out the components pretty fast.

We must now ponder about a better system based on Butch?s
success and see, how we can loosen the rotors from the magnets without
hitting each other.

Regards, Stefan.

Just trying to help out a little Stefen. My 2 cents worth is in ( )

The disadvantage is the permanent acceleration and deacceleration of the rotors
that will wear out the components pretty fast.

( Consider this a one cylinder engine which will never run as smooth as a V-8 or V-10. With several sets of rotors on one shaft I think the machine woule run pretty smooth)

We must now ponder about a better system based on Butch?s
success and see, how we can loosen the rotors from the magnets without
hitting each other.

( I believe that if the rotors each had a North North or South South magnet mounted in them for repulsation where they strike each other there would be no clackity clack or very little.)  Hope you understand what I'm trying to say.

Here's wishing Butch the best of luck.

What about hard rubber ends to stifle the impact?  Maybe a simple spring like those used in the valves of an engine?  Or both...

Hi,
thanks for the answers.
Well the problem integrating magnets into the rotors will be
very complicated, cause you have to watch then your total magnet field !
Will the rotors still be attracted to the stators or will it then repell also in this phase ?

I guess the idea with the hard gum or springs is more promissing.
Well, it will depend on how close really the 2 rotor steel plates must come
together to be able to push the first through the sticking phase..

I hope Butch can soon present a selfrunning motor and then we have to see,
how long the steelparts last, if they twist or bang each other too hard, so
that the support might get loose and the steel parts will stick to the magnets...

I think, Butch has the magnets much too close to the steel ! This way the
forces are there much to big and it need very much hard hitting to get the
first rotor to be loosended.

A wider airgap would be here more helpfull.
Regards, Stefan.

Stefan:

The repel magnets could be mounted in the insulated portion of the rotor. They wouldn't have to be mounted close to the striking part of the rotor and just powerful enough to keep rotors from banging against each other too hard.  ( Butch said for us to keep it simple) Hope he gets it running.

PS Might even be able to pick up elect. power from repel magnets which would serve as a dual purpose. Just a thought.
