6 Phase 180watt PMG project (7/23/13)
Hello dear viewers. Here again is another project I just completed using the new six phase design I previously used for a small 30watt PMG. This time I used it to sort of improve the 180watt PMG I am currently offering to the market.
My purpose with the change is to try to combine the features of the standard jumpered option and the low rpm option. For those unfamiliar with what I am saying, you can look at the webpage for the 180watt PMG or the 150watt PMG so you can catch up with my discussion here. In the previous designs, my customers have the option to use a low rpm setup so that they can output higher voltage and start charging batteries earlier even with not so fast spinning of the shaft. There is a trade off however as the current output rises slower with the low rpm option. Whereas in the standard jumpering, the current rises faster but the voltage is lower. With the six phase design, there are no more low rpm or standard option. The output is low rpm style but at the same time, the current rises fast. Thus combining the features of both option.
The nominal power is still 180watt. Hand spinning the device can reach 12volt DC output(at about 300). The rectifier uses three bridge diodes to accomodate the six ac output lines.
In the video below, the multitester is set to 10DCV. Thus it can read up to 10volt DC maximum. Watch as the needle exceeds the maximum displacement to the right of the meter. There is a small capacitor at the output of the rectifier to maintain the voltage for a while. Otherwise the voltage quickly drops to zero as soon as I stop spinning the shaft.
I can actually generate 12volt DC with my fingers spinning the shaft. In the video below, again I use a small light bulb to test the device. A single flick of the shaft brightly lights the bulb.
With my experience in making polyphase device, I can probably make a new project in the future that can breach the 200watt output. I am going to start with the design as soon as I can.:)
