Well, I think it was said of the mathematician Gauss that when he cooked, it took him a long time but the results were invariably delicious. Or something like that. I make chicken paprikash the farm way. It takes a while but it's good.
I've been writing about the 110 VAC motor/generator on the MOEPED (MObile Experimental Physics Educational Demonstrator) recently and the attempt to turn this motor into a generator is showing a steep learning curve and never ending challenges.
But I did figure one thing out.
Earlier, to vibration test all parts, I'd connected the rear-wheel driven hundred-watt DC generator to an AC inverter, then to the AC motor, which powers the cranks. It worked OK, but it was just a dynamic brake. Perpetuum mobile non.
Well, I finally realized what I did wrong there. I used a modified square wave inverter!
I've already got the sine wave inverter, and have mounted it once. I'd had it all along.
I think when I repeat the shakedown, it should provide a little more compelling ride than before, and in the meantime I'm going to have to educate myself with EET 350 at ODU via the video lectures that I hate. It's the only thing available to me.
Anyway, I'm setting the generator one burner over, and moving back to the shakedown, this time with a significantly more "pure" mobile AC source. That should keep me busy.
