Question for ya...

If it is a 5.5Hp Engine then... 1 horsepower is equal to 745 watts. Which at 5.5Hp it would be 4097.5 watts. If you only got 1000 watts then thats only about 1/4 of the power. Or is this at a lower RPM for this engine and therefor lower Hp? But if its not then that would mean you have about 25% efficient generator. Shouldn't they be a bit more effiecent?

Thanks,
-Randy

I was only able to run it to about 800 rpm. Full speed for this motor would be about 1150 rpm at which there would be an additional increase in power, how much I don't know. This motor was also built with relatively inexpensive ferrite magnets. If it had been built with neos the power output would have been much higher. Still in the long run a 1000 watts out of a free motor and some cheap magnets isn't all bad. Now the problem is finding time to finish the tower and the 3 to 1 serpentine belt speed increaser.
