Oh, idea. Those moving magnets can generate
electricity. Feed it back to the motor, and you have a perpetual motion machine.
Lets see who swallows that one...

From: owner-personal_submersibles@psubs.org [mailto:owner-personal_submersibles@psubs.org] On Behalf Of Thijs Struijs Sent: Wednesday, December 13, 2006 2:12 PM To: personal_submersibles@psubs.org Subject: Re: [PSUBS-MAILIST] Magnetic couplings After (simply) buying a coupling you would still
have to deal with the alignement of the two axes. When you look at the cut-away
picture you will see they apply a big and strong frame to achieve that. A small
misalignment will be increased by the force off the magnets. I think starting
from scratch might even be the easier way.
I have added 3 more links. One of them shows a
configuration in which the magnets are placed in 2 causers opposing each other.
It seems this is much more forgifing than the other solution. The
separation between the two parts is a flat disc. This might be a problem
under high pressure. Another problem is the axial force on the
bearings.
Another thing to consider if the influence of the
magnets on a compass and maybe other electronic components. Applied in
a ROV you can forget the compass.
