The Awesome Windmill Generator
Breana Harvell, Anna Carr,
Darius James, John Quigley,
and Robert Walker
The insulator is made of a cardboard box
The copper rod goes through both sides of
the box and serves as the axle
Red coated, copper wire wraps around the
cardboard box forming coils
Four magnets are attached to the axle,
inside of the cardboard box
The light is connected to the ends of the
A fan is attached to one end of the axle and
generates the power to light the bulb when
spinning at the appropriate pace
Straight fan axle linkage
Magnets magnetically attached to copper axle, which is spun by the fan or wind power
Magnets spin in between the spun coils, which collect and transfer the electrical charge to the light bulb
For the efficiency of our engine we use the equation:
Produced 16 Volts and ~ 0.1 Amps
P = I x V = (0.1 A) x (16 V) = 1.6 watts
Power generated = 1.6 watts
Period = 1 second
E = efficiency
Nb = gearbox/ bearings efficiency
Area = 49cm2
Ce = coefficient of performance
* 1.225 is assumed as the air density
We will combine the two efficiency values and coefficient of performance and let them account for the total efficiency of our generator
E = 62.805 % efficient
Our first cardboard box was
crushed by the pressure of the coils
Two of the magnets snapped into
The initial wire purchased was not
coated and was the wrong size
Difficulty getting the rod to stick to
the fan properly
Basically, our generator works.
The gauge of wire does make a difference in the intensity of power generated
As well as the coating of the wire
Creating motion between a magnetic field and a coated conductor, the change in charge over an area of the conductor will cause a charge to be distributed
coating and gauge
Fan positioning is not perfectly square.
Cardboard serves as sort of a insulator and absorbs some of the energy.
