🌬️ Pacific Sky Power Gen Project Review

To say that this alternator does not work as advertised is a gross understatement. I have used it with a small wind turbine with a rotor diameter of about 0.867 m and could not produce any significant power even with wind speeds up to 8 m/s. I am very disappointed as I was led to believe that the alternator started producing power at 500rpm (listed in the description) but this information is clearly misleading.

Technical design is really bad. The armature shaft is not suspended on ball bearings and therefore does not rotate easily. The shaft is only 2mm in diameter so I had to put a bushing on it to allow the 4mm pulley to fit snug enough to be securely attached to the shaft. Due to the lack of bearings, a lot of external power had to be applied to the shaft to get it to spin at a high enough speed to light a low wattage (0.1W) 12V lightbulb. This generator was used in a freshman science project on…

error loading media. I bought this for a wind turbine demo project. Judging by the appearance, the design of the engine is small, but worthy. I didn't take it apart to check the windings on the armature or the brushes on the backplate. I used heavier turbine blades so I didn't get very high RPMs when using the fan to drive the turbine, but you can see from the graph that the output voltage "no load" is usually linear with shaft speed, and I would expect the generator to require over 1000 rpm to
