[Electric Boats] Re: Efficiency of mars motor

 

A better way to ask my question might be "Is there an efficiency advantage to operating the motor at a higher rpm for a given KWh output?".

Finally figured out how to match the required HP to the HP for a given diameter/pitch. So now I think that my best propeller RPM should be 1020. So is there a best RPM to operate the 72 volt mars motor at? Best in this case would be RPM rather than maximum power.
