Does anyone know how big a 20MW synchronous motor would be to drive a ship's propellor?
How big are nuclear submarine motors? Off to google I go....
The P&O ship "Aurora" uses 20 MW motors but I can't find how big they are anywhere...
I googled nuclear submarine motor size, and got lots of hits. Here's one of the first ones -- pretty interesting info:
Oops, I just reallized that they drive the propeller shaft directly with the hot water turbine, not via an electric motor. My bad. But 35,000 shp is about 26MW, which is in your size range. Hmmm, what else uses a motor that size... Maybe an old diesel submarine. I'd head off to google again, but I need to get back to work...here comes the boss!
"Aurora" datasheet here
Well if that drawing is to scale, then that gives you the motor size, right? Is that what you're looking for?
