[PSUBS-MAILIST] thruster discovery

[hank pronk via Personal_Submersibles]

Alan,
Just talked to a buddy that installs these pumps.  He said you can get many voltage and hp combinations and they are around 400 dollars.  Also you can get a speed controller.  No brushes, no pictures.  :-)  they are about 4.5 in dia and 2 feet long and shiny ss body.

 Voltage is 220 AC  buy it
 gets better!  I discovered the bottom end of the motor has
 a very elaborate  thrust assembly and a rubber bladder for
 pressure compensation.  OMG  just remove the armature and
 machine the spline off and screw a prop adaptor on and your
 done!

  just dismantled a submersible
 well pump.  As I thought it
  is fluid
 filled and all SS, it seems like it is filled with
  anti freeze not oil.  This would make a
 beautiful
  thruster.  The output shaft is
 splined and a simple adaptor
  to a prop and
 your done, also a thrust washer should go
 
 in.  The armature rides on bushings, not bearings.  The
  wires are potted and plug into the motor
 interior. This is
  very interesting and
 should be explored more.
