New to the forum, and can't find this info or examples on the web. I'm interested in the possibility of coupling multiple DC brushless motors to a single drive shaft for main propulsion on a 45-50', twin screw boat. Lots of sail boat examples are given, but my interest is in a power trawler-style boat. Twin diesels of 150-250hp are standard on these vessels, but I want to consider using multiple smaller electric motors, say 3 x 50 kW motors per shaft. The motors would need to be assembled linear along the shaft to avoid major retrofit of the boat. My interest is in redundant systems, ability to carry spar parts, ease of installation, etc. Rather than contracting an engineer to design it, are there any gaping holes in my plan? Thanks!
