Variable drive idea
At a recent OTC show in Houston, SWACO, a oilfield services contractor, was
showing off a mud centrifuge with a unique drive system. It consisted of a flywheel with rare earth magnets mounted on it and a solid copper flywheel opposite it. The closer the rotating magnetic flywheel gets to the copper flywheel, the more rotational energy is transfered. With the two flywheels close together, both would spin at the same speed. As they were seperated the driven flywheel would slow down, and with enough gap, completely stop. No energy comsumed to operare as a variable speed tranny and clutch. Picture the implications of this in the auto industry future. Never realized that a magnetic field would affect copper. I'm talking about a 100hp(?)motor rotating a 1000#(?) centrifuge bowl and rotor |
