theory right or wrong?
« on: October 19, 2013, 08:02:51 PM »
hey guys, just had a thought, its so simple im sure its been done before but wanted to check with you guys

Ok, so I am building something that turned out not to work due to the center of gravity being off and causing the motor extra strain that i didnt anticipate etc etc.

anyhow, when sped up (say 1000 rpm) the center of gravity moves back into alinement with the crank shaft so that the only resistance to the motor is that of the bearings (and a tiny bit of wind resistance)

now using centrifugal force, couldnt someone put a couple of magnets on the weights and have them rush past coils around the outside
(im not good with words and its 2 am now), would the resistance of the magnets be passed onto the motor or would centrifugal force take the brunt of the resistance?

em rephrasing,
spinning something at the center of gravity is very easy, even if its a 50kg weight, now if two equal weights on soild polls and connected to a crank shaft via another couple of bearings, and the crank shaft were spun at such a speed so centrifugal force would kick the weights out, the only resistance would be some air and the bearings (once spun so the weights were completely out).
now if these weights had magnets attached and the magnets were rushing past coils and creating resistance, would the resistance be absorbed by centrifugal forces, the weights them selves or the soild bars, or would the resistance be passed onto the motor spinning the crank shaft?

if its not clear what i mean please let me know and I will try and retype it (im dyslexic so while i can look at something and think the point has been made, in fact it just leaves the recipient with confusion)

Hi
I think it will work more or less as a flywheel. Weights will help
to overcome the resistance when magnets get engaged by the coils,
but when magnets disengage, motor will have to work harder to renew the speed.
