Hi John.
I was wondering if this idea might be practical for
your applications.
Suspose you rigged your motor to work with the
RimTec magnetic clutches.
Then suspose you filled the inside of the enclosed
casing holding your already waterproof say...minnkota
motor with either oil or water before you sealed it. Then when you were at depth, the
outside water pressure
would not push against the sealed casing holding
the motor. Then you would not need a thick
barrier between the mag plate and the clutch. Would
that work?
Bill.

Magnetic Clutches
Hello fellow Psubbers,
I have looked very closely into
RimTec magnetic clutches about a year ago. I encourage everyone else to check
it out for themselves but I found they were very limited by the type of
barrier that one could have between the shaft mag plate and the mag
clutch. Less than 6 mm in most cases which was not practical for my
application and the pressure I was looking to work with. The barrier has to be
non-magnetic of course.
There is also a significant
limit to the torque they can transmit through a barrier this thick. Since they are custom made, they are
also very expensive. Much more expensive than building a good quality shaft
seal. I was very hopeful at first but do not feel they would be successful for
a 1 AMT psub. Be sure to check them out for yourself.
John
