Re: Powering a 12 ton boat; need advice on big DC motors
Can you use a large squirrel cage fan (oversized furnace fan) and duct in cooling air?
The 40 hp table motors at the steel mill where I worked live in an environment that can be as much as 50°C and draw air from the oil cellar at 30°C for cooling. The motors can be operated on as much as a 20% duty cycle
Rule of thumb - 1 hp electric motor = 1.25 hp gas engine
I'm not sure if a diesel equates the same way.
