Waterproof Steering Coupling - Magnetic Coupling
A magnetic coupling is used to transmit the Steering Servo movement out of the water tight compartment to the rudder pushrod.
This has been successful.
In the correct configuration, all six magnet pairs are engaged.
It can suffer the problem that the outside disk can be forced to detent in the wrong place, one sector in either direction.
In this position, two magnet pairs are attracting and four are repelling.
It is a semi-stable state, but it can easily be pushed back to the corrected alignment.
The pattern of magnetic orientation has an effect on behaviour, and more study is required to determine the best arrangement and quantity of the magnets.
Perhaps less magnet pairs are better, because the angle to next detent point would be greater with a reduced number of magnets.
This would need to be balanced against the reduced magnetic coupling with the reduced number of a magnets.
