DC motors can be utilized for a wide range of chores and projects, from more practical machinery like circular saws to amateur crafts like fans or makeshift drills. DC motors provide a plethora of applications that can simplify your life. I’ll show you how to build a solar-powered DC motor that can run a fan in this Instructable.
This simple fan project can be used for a variety of purposes, such as cooling off in the heat of the summer or as a fume extractor when soldering. Its built-in battery allows it to function even when the sun isn’t out, which is a benefit.
Materials and Tools Required
Materials:
- Mini DC motor
- Positive wire
- Negative wire
- Battery holders
- Solar cell 1.5V 100mah (Dollar store garden light)
- Popsicle stick (Fan blades)
- Diode
- Battery (I used a NiCd 1.5V 300mah AA battery, also a 9V works the best) (More voltage faster the RPM, don’t exceed 12V because the motor might break)
- Ceramic capacitor (To minimize RF noise)
Optional:
- Propellor
- Resistor (If necessary)
Tools:
- Soldering iron
- Solder rosin 60/40 core
- Electrical tape
- Wire cutters
- Drill (Not shown in diagram)
- Voltmeter (Not shown in diagram)
Circuit Diagram
The circuit itself is rather simple, and the diagram will show you how the circuit’s parts are organized. Replace any batteries or other components you are using to boost the voltage with the ones I have. Depending on the battery type you use or the solar cell you use, your setup will decide how much resistance you need.
Set Up Before Soldering
Verify that you have seen the schematic diagram mentioned in above step before continuing. Before you solder everything, check everything over once you’ve set up everything as the diagram indicates. While carrying out this technique, you can allow your soldering iron to warm up.
Solder your Components
(Never solder on a table; this was only for demonstration purposes. Hold the wires with clips or a third person’s hand.
After everything is lined up, get ready to solder everything together as the diagram suggests.
The Fan Blade
I made a fan out of a popsicle stick, and I shaped the blades to produce the most breeze possible. Just enter “fan blades” on Google Images to find tutorials on how to make efficient blades. I suggest utilizing a plastic small propeller, which can be bought at RC retailers or even from old, broken RC toys, for blades that are more realistic and efficient.
Connect Fan Stand (Optional)
You might build a tripod mechanism to attach your fan if necessary; I used a cap to support mine.
Finished!!! Feel the Breeze of Free Energy!
You can now own a portable, self-producing DC fan. The wind generated by the popsicle was adequate, but a plastic propeller would likely be more efficient. I also tried a 9V battery, which was also more potent. Also, I would advise making these improvements
.Hope you find this project simple. Superkitz will be back soon with more informative blogs. Thank You Bye.
