Title of Activity:
Project Progress.
ü Development of Windmill as Electricity Generator (The rotor part)
Objective:
- Construct the rotor part for windmill.
- Combine the rotor with the turbine part.
- Tested rotor part as a wind turbine.
Content/Procedure:
- Using the compact disc, make it as a base part of the rotor. Use the plastic tap washer as a holder and glue it at the centre of the compact disc.
- Take a ruler and mark one side of the rotor disk with perpendicular dot marking. Be sure the two lines are 90 degrees apart. Use geometry square or the corner of a piece of paper to help locate the second line.
- Hot glue the 4 fender washers to the disk, centre them over the dot mark and bringing their edges up to the edge of the disk. And be sure the washers are clean and free of all grease and dirt.
- Carefully separate the magnets by sliding them off the stack, one at a time. And place a magnet on each washer with the same pole facing up (north or south). To unsure the polarity of the magnets, we can use a magnetic compass to confirm that all the magnets are either north or south.
Result and Analysis:
Tools and Materials are used to make this turbine part are:
When finishing this rotor part, this part has been tested together with the turbine and the coil parts. As a result, the wind turbine has generated some voltage. But there have some problem, the output voltage are too small. For improvement, I should re-check coil orientation. Following the wire through the circuit, it should spiral through the first coil in either a clockwise or counter-clockwise direction, and should go the same direction in each of the other coils. I also should re-check the gap between magnets and coils is not too large and the rotor is stable.
Conclusions:
As a conclusion, the rotor part is the important part because the magnet that is used should be more powerful and the rotor also should be rotate in a stable rotation. And this rotor part also should be able to combine with the other part and can generate the electricity. And for the problems that occur for this part also have been resolved with some discussion and research.
