The Turbinator!
Hasta la windmill, baby.
The Team
Keshia Agazuma
 Corie Davis
 Alex James
 Jamison Trent
 Lee West
The Device
Fan Blades attached
to pulley system
 Pulley connected to
magnets of the
 Turning of the
magnets induce an
electric current in
the coil
Mechanical and Electrical Components
 The
fan blades turning produces
rotational kinetic energy which is
transferred through the pulley system to
turn the magnets.
 The magnets’ motion produces a
magnetic field which then induces an
electric current along the wire
P = 0.5 x ρ x A x Cp x V^3 x Ng x Nb
P = power in watts (746 watts = 1 hp) (1,000
watts = 1 kilowatt)
 ρ = air density
 A = rotor swept area, exposed to the wind
 Cp = Coefficient of performance
 V = wind speed in meters/sec
 Ng = generator efficiency
 Nb = gearbox/bearings efficiency
P = 0.5*1.164*0.0248*0.35*1.7^3*Ng*0.80
 Power was measured to be 0.00288 W
 Solving for Ng (generator efficiency) this
gives a value of 0.15 or 15%
Design and Construction Issues
 Negating
friction that is caused by the
pulley turning against the wood.
 Attaching the coil so that the magnets
can spin freely.
 Bearing accidentally immobilized with
super glue.
 Magnets too heavy
 Wind
from fan is not that powerful,
design must be light.
 Stronger Magnets + More Coil = More
 Complicated design produces more
problems than benefits.
