Hi Alec,
The servo is a 24VDC motor with worm gear/ thread spindle reduction. No electronics are planned and the spindle has a adjustable endswitch. I have a mechanical background so I “avoid” complicated electronics…….
Zero position is given by a rudderposition Indicator. You know the sensor can be a simple potentiometer
So all by the KISS rule. However, I understand the benefit of electronic control; I think it is very useful on a sub to have a steering servo that can be linked to the (gyro) compass.

Hi Emile,
I always enjoy looking at20the 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,
Alec

Hi all,
Good progress on our Kreideseesub/ Eurosub20project.
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 so20the hull can be sandblasted and painted.
