Building the Improved Turbine

Meeting One – Wrapping coils, cutting plexi, and building base

Meeting Two – Change in plans, mapping out design, cutting out new rotor

Meeting Three – Cut rotors smaller, assembled rotor and connected coils

Meeting Four - made another design change and trimmed plexi off the

Meeting Five – Began basic wind and voltage testing

STARTING PICO TURBINE

[pic]

Our team built and tested 2 original Pico Turbine kits. When one we thought was the stronger of the two failed due to design flaws and shoddy materials, we decided to improve upon the original using better components.

Building of Improved Pico Turbine:

During a meeting after the 11/6 class, we came up with 2 possible concepts for our improved wind turbine.

One was a Triple Helix Wind Turbine. It is a lift design, and therefore it could spin faster than the wind speed.

The other was a Double Helix design; it caught wind from all directions, and was sturdy enough to endure high wind speeds. We agreed that this design would be the way to go.

We agreed to have our first meeting on 11/8 at Tyco in Cranston.

MEETING ONE

Our first challenge was to build the coil base. We decided to use 12 coils in a 3 phase configuration with gave us 4 coils per phase. Each phase was wired together in a star configuration to maximize voltage output in low wind. To have a total measurable output we rectified the 3 phases into DC with 6 diodes for ease of data collection. The 4 new Coils were hand wound 200 turns each with approximately 7 ohms per coil. Then we cut out the plexiglass to insert the coils and suspend them between the magnet layers. The magnets consist of the original 8 picoturbine magnets double stacked on two disks with four magnets on each disk. The magnets were backed with a piece of carbon steel to help concentrate the flux lines to make the most use of the magnets.

MEETING TWO

After careful consideration, our team decided that our Triple Helix design would have structural issues with increased wind speed, so we decided to go with a drag based Double helix that was similar to the original Pico – but better. We continued building the base while we thought over a new plan.

After a few days debating the material for the blades, we decided to build them out of fireproof foam.

MEETING THREE

We cut rotors in half lengthwise to create better wind flow, and the ability to stagger the blades further apart

MEETING FOUR

After initial testing, we discovered that the weight of the plexiglass became an issue. So to compensate, we removed as much material as possible from the magnet disks; as per our model below.
