DESIGN
-Basic structure is 2
crossed rods
-Generator (G) is
supported inside
-G consists of 2 sets of
copper wire wrapped
700 times around tube
-1st rod holds G, 2nd rod has a magnet attached
to it and is attached to windmill’s blades
-Fan blows blades, spins rod and magnet,
generates electricity, lights bulb
MECHANICAL/ELECTRICAL ASPECTS
 Wind Power
 Causes blades to spin and rotate magnet
 Generator
 Spinning magnet causes current to flow through wire
 Light
 Energy from generator lights bulb
ESTIMATED EFFICIENCY
 Power = 0.5 x rho x A x V^3
 rho = 1.225 kg/m^3
 A = 48 in^2 = 0.03096768 m^2
 Velocity = 1.7 m/s
 I = .0176470588 amps
 Voltage = 1.7 volts
 P (theoretical) = 0.0931883298 watts
 P (actual) = Voltage x I = .03 watts
 Efficiency = (actual/theoretical) x 100 = 32.2%
DESIGN ISSUES
• Actual design
– Getting our structure together
•
•
Knowing what we wanted to build
Measuring correctly
• Generator
– Making it work
•
•
Getting the right kind of wire and stronger magnets
Figuring out how many coils we needed
• Getting high voltage
– The Generator
•
We had to get our magnets to spin perpendicularly to our coiled wire
CONCLUSION
-Through all the planning and
struggling, we were able to
put our windmill together
successfully and get some
voltage out of it.
