[PSUBS-MAILIST] 36v alternator

[k6fee via Personal_Submersibles]

Hank,
What about using a surplus golf car motor as a generator? I know they are 48 volts and if you run at lower rpm you should be able to get 36v out, I would think.

            Brian, On 24v the motor takes 70A  so at 36v it should be around 50A  so I don't think a charger will do it.  I like your AC motor idea, except that I intend to switch over to AGM when I dive and will drive the sub with the main motor.  I have to give it to the Nekton engineers, that drive with a rudder, really works well.  The addition of positioning thrusters up front will be perfect.  It would be different if I didn't use gamma as a boat and sub all in one.  I sure like your idea! I  am going to see if I can find a 3hp universal AC\DC motor.Hank

                    Hank,       If you did have one I wonder if that would work.  I think they put out about 10 amps.  But there may be a duty cycle issue running a charger for that purpose may shorten it's life.  What about just running a AC motor off of a regular AC generator for the sole purpose of getting across the lake?   Brian

            Brian, I don't have a 36v charger.  I charge my bank 12v at a time.Hank

                    Hank,    Does your 36 volt charger put out enough amperage to power your motors ? Brian

Okay new idea, can't fit a diesel in my escape pod, so, I am thinking that I will put a 36v dc generator (home made) in my inflatable tender that I tow behind Gamma.  I am installing the original 2hp drive in the escape pod with the jettisoning prop assembly.  I will feed the 2 hp 24v motor with 36v so it will be 3hp.  The motor is rated at 3hp 36v.  I will run a power cable from the generator to 3 12v batteries in the pod, and I will travel on that power.  When I dive I will switch to my 36v agm  bank.   That should work since I am towing the tender anyways.  I am having trouble finding a 36v alternator.  I want an alternator with internal regulator.  I guess in a pinch I can use 3 12v alternators but then it is not compact anymore.  Any ideas?Hank _______________________________________________
