[PSUBS-MAILIST] Electircal System

[Alan James]

Hi Brian,
looked at your project page & am a bit confused.
Are you still using the diesel motor? & is the electric motor going in the hull & turning the 
propeller shaft of the diesel motor?
Also does the concrete exostructure incorporate ballast tanks or are they going to be attached 
to it? What are the dimensions of the pressure hull.
Regards Alan

Lower RPM and a lot of start up torque.   

This page has some additional motors with other voltages:

Why such low voltage on a motor this size? Those kinds of amps are going to take weld cables to manage.

Actually this one might be better, lower RPM

Sounds good.

Think I may have found a motor with an rpm curve that could fit the bill !   Going to talk to the golf cart folks tomorrow !

Well, that ought to give you something to ponder.

Cool,I know anything above 36 Volts can be problematic as far as getting accidently zapped.  But with the controllers they have now I could run a 48 volt AC induction motor from a DC power source.  That would be nice as far as smooth control capability and also I could run the motors in mineral oil and would not have to worry about any brushes.  However the rpm may be a problem unless I have some type of gear reduction.

Brian, 

Delta did 6000+ dives with a hull grounded 48 volt system without problem. Just saying.....

Hi All,
            I'm considering a 48 volt system for my motors, is that too high of voltage as far as safety goes for a sub ?
