Procedure
- Built a Rotor (See Figure 1)
- Cut a circle with a 140mm diameter from corrugated
plastic;
- Attach the Rare Earth Magnets, with North Pole to top,
to the outer rim of the circle using a glue gun;
- Insert a Lego Axle connector to the centre of the Rotor
and glue with glue gun.
- Built a Rotor Base (See Figure 2)
- Built a 18 Lego block high tower where the Propeller
connects to the Rotor using a Lego Axle.
- Make the Coils (See Figure 3)
- Make a winding jig by folding a small piece of
corrugated cardboard over itself three times;
- Width = 30mm, Length = 200mm;
- Secure with electric tape;
- Wind the wire onto the jig, making 4 coils of 200 turns
each.
- Built a Stator (See Figure 4)
- Cut a rectangle from corrugated plastic;
- Width = 120mm, Height = 227 mm;
- Attach four Coils to the upper part of rectangle.
- Built a Circuit (See Figure 5 and Diagram 1)
- Used electronic components to built a Bridge Rectifier
so that electric power can be converted from Alternating
Current to Direct Current.
- Built a Wind Turbine
- Assemble all the previous parts as shown in Figure 6.
- Built a Wind Meter (See Figure 7)
- Used Lego Blocks, Cardboard and a Paperclip to build a
model.
