[PSUBS-MAILIST] 36v alternator

Tue Oct 17 05:53:02 EDT 2017

 Kieth,I have an extra 36v golf cart motor here, but there are two problems ,I think, anyways.  My understanding is, for a dc motor to work as a generator it must have permanent magnets, I think?  The next problem is the sheer size and weight.  these motors are quite heavy, witch is probably why they are so robust.  If it did work, it would be very tough and reliable.Hank

 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 _______________________________________________Personal_Submersibles mailing listPersonal_Submersibles at psubs.orghttp://www.psubs.org/mailman/listinfo.cgi/personal_submersibles_______________________________________________
