Hi 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. Regards, Van:
owner- Hi 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,

owner- Hi all, Good progress on our Kreideseesub/ 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, Hobbemalaan 54 1816GE Alkmaar 0031-72-5122401 / 0031-6-46375374 No virus found in this incoming message. |
