Winter

Preliminary Design

Initial Model and Design

Magnet

Rotor blades

Gears

• Four fan blades at 45° angle

• 1.6 to 1 gear ratio

• Neodymium magnet

• 30 gauge magnet wire

Mechanical Aspects

Construction issues:• Basic design layout

• Stability of the Fan

• Reducing the friction

• A more efficient generator than our test generator

Possible Improvements

• Increase amount of wire coiled• Increase the wire gauge• Increase magnetic field• Make higher gear ratio• Reduce friction• Use nonmagnetic materials for housing of magnet

ConclusionDespite construction issues we were able to produce a wind

generator that successfully met the guidelines.
