Turbine Open Circuit Voltage Test Results

Detail Description |
Detail Photo |
|
Our Group constructed and successfully tested the Picoturbine in its original conception, achieving the highest power output of any of the class groups. Although we originally discussed modifying the original design, we eventually decided to devote our time developing a horizontal, drag-based design, due to the constraints and limitations of the Pico design. |
|
|
|
|
|
After deciding to expand our HAWT design to include a total of 8 coils and 16 magnets, member Greg Gobeli assembled the photographed armature. We decided to mount the magnets on twin stators with the coils attached to the rotor. Power would be transmitted via the coils soldered to the copper axle transferring power to flexible steel brushes, and on to power terminals. |
|
|
Each stator could be adjusted in proximity to the rotor to maximize magnetic field strength. |
|
|
Each stator disk was constructed of plexiglass with cutouts for the insertion of eight magnets. |
|
|
Turbine was bolted to baseplate with terminal connections. |
|
|
Rotator consisted of bolted-on plastic blades cut and attached to discarded 23.5 inch bicycle wheel. Blade pitch was adjustable and we lubricated bearings in wheel cage for maximum efficiency. |
|
|
Power would be transmitted from perimeter of wheel with light belt using wing-tip to center speed ratio. Wheel was mounted with adjustable tensioner to set appropriated variation in belt tension. |
|
|
Eventual testing demonstrated maximum power transmission with a downwind setup with blades pitched at approximately 45 degree angle and loose tension on the drive belt. |

Turbine Test Procedures:
We positioned the completed turbine approximately 6 inches away from a window fan controlled by a rheostat that allowed us to vary the speed. We used a hand-held digital anemometer to gauge the equivalent wind speed. Testing was done at various wind speeds with no load, with a 100 ohm load, and with a 200 ohm load. Although the internal resistance of our turbine was measured at 55 ohms, we decided to use the 200 ohm load for standard testing.
Turbine Open Voltage Test Results:
Power output was predictable along the standard curve with power increasing exponentially along with corresponding increases in wind speed. Still, considering the quality, size and amount of materials that went into this project, power output was slight, implying increased size and efficiency of wind turbine would lead to increased cost-effectiveness and practicality.
