Hello again fellow hobbyists, enthusiasts and plain viewers to my website. It has been a year since I made my first 150watt PMG. Since that time, I summoned the courage to offer the said project to the public. This is mainly to help support additional projects I plan to do and also to check if the unit is at least marginally marketable. I am pleasantly surprised that it met my expectations and would help me financially sustain my endeavors.
Now I am presenting in this webpage an improved version of the 150watt PMG. This is a 180watt variant. The output is not so very far from the original. I made several design changes in its internal makeup to improve the output. Below is a picture of the unit.

Here is another picture with a rectifier attached to the unit.
The unit is very similar to the original. Much of the specs is the same except that it can output 20% higher power. As I mentioned, I only made internal tweaks to increase the power output. The dimension is almost the same. Just a bit heavier but still less than 2.5kg in weight. I also used now a thicker bolt for the shaft which is about 1/2 inch in diameter. It still also features two wiring options if I want a higher voltage output as a low rpm option. Below is a couple of short videos of the unit . The first video shows me lighting a small bulb with just a few quick turns of the shaft using my fingers. It is still quite stiff to turn. Remember in the original PMG I still needed a chain ring to help me manually turn the shaft and adequately light up the small bulb. This time my bare fingers is enough.
Another video below shows the PMG lighting a 12volt car bulb. This time I used a fiber plastic to help me increase leverage while turning the shaft as the bulb gives stiffer resistance to shaft turning. In both cases anyway I did not have to use a hand drill to turn the shaft.
In test with a 12volt lead-acid battery load and using a hand drill to turn the shaft, I see about 15 amperes going into the battery. If used in a wind turbine set up and in a strong wind condition, the PMG can be good up to 200watt output. It has rpm/volt rating of 20-30.
I plan on offering this unit to the public also so for those who would be interested, please go to www.sulit.com.ph. I also advertise the 150watt PMG there. Just type wind turbine generator in the search box and you will see my project among the listing.
In the future, I also plan on making a small PMG in the 50watt and lower range output. This can be useful for high school or even elementary student projects on renewable energy. Or it can be used by hobbyists to make portable power sources like for lamps or even small radios. Any income I derive from sale of my projects goes into other projects like this one. So I thank those who have bought from me and also those who will buy from me as they sustain my projects in reality.
Thank you and happy reading again.
