Yeh, pardon my old so-fist-ic-ated ass, but I wanted to see the windings and rotor of the actual motor, and get an idea of just how it changes speeds, I ASSume by varying the freq of the input power....from looks of the 3 pin spade lugs there, the windings are about 1/4 inch thick, copper I would ASSume....
reading up on my friend's solar panels, and the theory/practice of the power panels they use some ....shit,...can't think of the name/type of transistor/control device, but it's forward voltage drop is about zero at silly high amp/current levels....like .5 volt.......
so the same I ASSume for the control device, just that it seems like awful massive for the heat sinks on their main power control switches,.....by comparison that is.....
