Hi Emile,
I always enjoy looking at the solutions you come up with.
Can you tell us more about the servo and it's control electronics? My sub has a
PLC on board and I was thinking of leveraging that to control the rudder
and dive planes. So far I was thinking of using large stepper motors, and
to prevent them from pulling a continuous current to hold position, the
control surfaces are balanced. But a worm gear of course holds it's position
without any current draw at all, so is a very interesting idea too. What I'm
wondering about is whether or how you feed the motor position back to
the electronics.
thanks,

Eurosub project. http://picasaweb.google.nl/submachine55/Kreideseesub#
see the last pictures. This weekend we cut, fit check and
step weld the main ballast tanks. Carsten decided to make the MBT from
Alu instead of GRP for production and safety
reason. Also the steering servo an spool for
the emg. Buoy are in This month all metal work will be
finished so the hull can be sandblasted and
painted. Regards, Emile van
