I want to convert my 30 ft. boat's V8 gas-guzzlers to 2 DC electric motors that run with a 10KW generator. I'm going to have batteries for running lights, bilge pumps etc., but I want to run the motors with a generator only. What would I need?
Hi, Tim - I think you're asking a lot from a 10 KW generator.
If you've got more than one big V8 engine powering your boat, you can figure on one big DC motor (A NetGain TransWarp 11 or 13?) with its own big (30-40kw? More?) generator to give you the same kind of power.
In a car, the size of the generator is really dependent on how much acceleration you need, because that's where you burn the energy. The boat is pretty much the same, I think. You need the most energy to take off, then less after you reach cruising speed. Right? The trouble here is that if you don't have any storage batteries, you need a larger generator to provide enough power for acceleration.
You didn't say why you don't want to use batteries to run your motors, but I guess you've got a good reason. Me, I'd prefer a battery pack to a bigger generator.
Good luck with your project, Tim!
