[PSUBS-MAILIST] Electircal System

[vbra676539 at aol.com]

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

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 ?
