I have a micro hydro setup. The generator is a 3-phase AC motor scavenged from a Segway ES2 scooter rated 36 V, 300 W continuous, 700 W peak. It is being rectified to DC.
I thought that would be sufficient, but it appears I can get more power from the water source than I thought, and the motor may well generate well over it's rated limit as a motor. Great news.
My question are - will running it at RPMs that generate > 36 V & 300 watts damage the motor? I assume it will.
Obviously I can get a bigger motor, but I have access to more of these, cheap.
My second question is can I run two of these motors in parallel? Bolt one on top of the other, off the same shaft, so both are rotating at the exact same RPM, theoretically delivering exactly the same voltage and current.
To do so, can I combine both 3-phase outputs to my DC bridge rectifier? Will that work, or will I blow something up?
