[PSUBS-MAILIST] Elco Motors

[via Personal_Submersibles]

Joe,


A good idea. Paul M. reckons the dsl/elec hybrid makes for the best psub for the obvious reasons, and so did Captain K. Autonomy is good. If it's 7-8K for the entire system, I would suggest that it ain't bad, considering. Then maybe add a variation on Hank's shaftless coupling, perhaps?

Very interesting and informative data on Elco's marine website pertaining to sizing, rates of discharge, range, and hybrid matching http://www.elcomotoryachts.com/ep-600.shtml

I don't think its possible to scratch build the reliability of these particular types of products in the electric boat industry, these are fully engineered systems. At 7-8k, its an expensive motor and would have to be inside with a rotating shaft seal arrangement, but coming from an experimental aircraft perspective the price points on these motors is a comparative bargain. I'm looking at these from a long distance surface transit standpoint for the Seehund.
