Creating a working model of a Mini DC Gear Motor Fan is a classic science project that demonstrates the conversion of electrical energy into mechanical energy.
Using a geared motor is a great choice because, while it spins slower than a standard hobby motor, it has more torque (turning force) and is much more stable for a sturdy desk fan modelPush the plastic propeller onto the gear motor shaft. Geared motors often have a "D-shaped" or flattened shaft; make sure the hole in the fan blade aligns correctly.Inside the motor, electricity passes through coils of wire, creating a magnetic field. This field interacts with fixed magnets inside the motor casing, causing the shaft to spin.Because you are using a Gear Motor, internal gears reduce the high speed of the internal motor but increase the torque. This makes the fan powerful enough to move air consistently even if the blades are slightly heavy.: If the fan is blowing air backward, simply swap the two wires connected to the motor terminals. This reverses the polarity and the direction of spin.
Use markers or paint to make your cardboard base look like a real household appliance.
Safety: Ensure the fan blades are securely attached. Since geared motors have high torque, a loose blade can fly off with force!
Would you like me to help you write a "Project Report" or a "Hypothesis" to go along with this model for your science fair?
