Is there some kind of duty cycle on this motor? The 75Hp could be for a short period of time. The air compressor in our office/workshop just runs for a few minutes at a time. (And it makes me jump each time it starts) The marketing people will of course cite the maximum power. [Linked Image]

Another thought: If both voltage and frequncy are increased 20%, wouldn't that mean that the power too increases 20%?
