[PSUBS-MAILIST] Fw: motor

[Alan via Personal_Submersibles]

Hank,
I Assume the seals are just rubber rotary seals like the Minnkota.
I have a few Cheap Chinese trolling motors. These ones might be
of a better standard. 
I would love you to buy one so I can find out how they are constructed,
but it is a bit of a gamble. It may be that it is a great find & you can
modify the seals easily. 
Emile was running the Protruar 2 hp brushless geared thruster on his sub,
& said it was a bit noisy. I believe he has now replaced it.
I was drawing an extra 1 amp off 50V (50w) on full throttle with oil (10cst)
in the housing. So it's not too much of a loss on a 2000W motor.

> You say they have a substandard seal, what does that mean.  Surely they hold the water out.  Would the seal configuration determine wether it is air or oil compensated.  The part I like is the power ratings, forget thrust because that is all crap.  But the amps, watts and volts, you could assume to be true.    Maybe if the seal is poor, it could be upgraded.

What do you think?  it has a controller inside the motor, not sure that can handle pressure.  maybe the controller can be removed and kept inside the sub.  I want to add two motors or more for long distance travel with an independent battery bank.  The current set up is to slow.   I figure this is better than adding a diesel engine.
