4.0 out of 5 stars Decent Construction, Low Power Output
By Patrick Ferrell on July 24, 2020
I purchased this for a wind turbine demonstration project. From outer appearances, the motor construction is not great, but decent. I did not take it apart to examine the windings on the armature or brushes on the backplate.
I used some custom heavier, turbine blades, so I did not get very high RPMs when using a fan for driving the turbine, but you can see from the graph that the "No Load" voltage output is generally linear with shaft RPM, and I would expect the generator to require over 1000 RPM to reach 12 VDC no-load output. When attaching LEDs or an appropriate step-down circuit to charge a cell phone or run a USB-connected lamp, I measured output powers between 100 - 350 mW.
I attached a 15-in, 2-blade "Pacific Sky" turbine blade to the generator and got a no-load output of 15.5 - 17.5 VDC in a 4-4.5 m/s wind (as shown in the video), but had no way to directly measure the RPM of this particular blade. Extrapolating from the earlier data, I estimate 1400-1500 RPM. When attached to a 10-ohm resistive load, the voltage dropped to 1.3 - 1.5 volts, indicating an output power of around 200 mW, but I did not try to determine the optimum load for this blade configuration.
For the price, it's a bit expensive for a child's science experiment, but it seems to have limited capacity at low wind speeds (~4.5 m/s) to do much besides trickle-charging phones or perhaps 12V batteries with the appropriate turbine blades and circuitry.
