[PSUBS-MAILIST] power converter

[hank pronk via Personal_Submersibles]

Alan,The motors are air filled with upgraded cartridge seals.  No compensation required.  I was thinking  I could run them on 48 volts if they provide enough power to move the sub.   I will do a test at the lake tomorrow, I tried in a garbage pail, all I did was rotate the water lol.Hank

 Hank,are they oil filled motors?I am thinking that if they aren't, then you might get away with drawingmore amps on a lower voltage for the same load, if you could keep themotor cooler with oil compensation. You could put a temperature sensor in the thruster to make sure you don't over heat it.I intend to do some temperature comparisons between oil & air filledmotors in the next Month.Cheers Alan

HELP,,,Turns  out my Perry thrusters are not 36V but 120 Vdc.  I can only manage 48V dc from Gamma's battery bank.  Can I step the voltage up with something.Hank
