30watt PMG Project (7/11/2013)
Hello to the viewers of this webpage, first timers or otherwise. Before anything else I would like to offer my thanks to all those who have patronized my other projects(the 150watt and 180watt PMGs) when I placed it as a commercial offering, and thereby made it possible for me to pursue additional projects. This time my purpose is to assemble a small experimental PMG using a different design and with more coil phases than the usual 3 phase devices. Whatever I learned from this project, I hope to be able to use to make better PMGs or at least improve whatever I am already offering to the public.
The completed device has six phases(as can be seen from a close up picture below) and therefore has six external line from the terminal block towards the rectifier which converts the six AC line into a single DC output.
The output can reach 15-16Vdc via hand turning only which I would consider as already low RPM range(~20rpm/volt). In the short video below, a single quick flick of the shaft using my fingers propels the needle of the multitester to more than the maximum. Please note how the needle moves beyond the maximum readout to the right. The tester is set to 10DCV which means it can read a maximum of 10volt DC. I just shorted the output to reset the tester and made multiple trials.
In the video below, I set the tester to 50DCV which means the maximum it could read is 50volt DC. Several turns on the shaft made it reach about 15-16volt DC. I also placed a small capacitor at the output(100uf, 25volt rated) to retain the output so I can read the result. Without the capacitor the reading quickly goes down to zero as soon as I stop turning the shaft.
In the next video below, I connected a small bulb to the output. A single quick flick of the shaft brightly lights the bulb. It performs the same as my 180watt PMG in powering a small bulb since it reaches a high enough voltage easily. Although of course the ouput saturates more quickly as it is of much lower rating.
Tests using my multitester for short circuit current yields about 125-150mA using my hand only. Using a hand drill to turn the shaft and small 12volt battery as load gives more than 2 amperes reading. This gives about 30watt power output.
Well this is all I can say about this small PMG. Until my next post of a new experiment. See you again.:)
