[PSUBS-MAILIST] rpm

[hank pronk via Personal_Submersibles]

Vance,
Yes for sure, Gamma has two separate amp gauges, one for the motor and one for the rest of the sub. All 24v and the trolling motor is 12 v

 Yeah, too
 simple. Maybe that's a good guess, but..... I will say
 that an ammeter in the boat is a good thing. You can keep an
 eye on things, and if it goes UP at some stage, you would
 suspect a thruster issue (a tangle, or a bearing failure or
 whatever). All it takes is an appropriate shunt and a gauge
 (in my pre-digital steampunk mind). Okay, thanks anyway. I
 was curious, that's all.

 Vance,
 I did not do an amp draw test because I do not have the
 technology in house. I 
 would guess with a 10% rpm drop, there may be a 10% amp
 increase. That would be 
 to simple :-)

  Hank,
  Did you check the amperage? I wonder if the
  resistance causes a higher draw, and if so, how
  much?

  I am working on a hydraulic
  pump that will be external and pressure compensated 
  in oil.  I am using a trolling motor to drive the pump.  A
  while back there was 
  a question about rpm drop when a trolling motor is filled
  with oil.  I bench 
  tested that today, and the motor runs at 2,000rpm stock and
  1,800 rpm full of 
  WD40.
