| Summary: | Demands for electrical energy have increases every year. This demand inclination
effect the cost to generate electricity. As a consumer we need to use an efficient
electrical appliance to avoid waste of energy. Ceiling fan is among the most use
electrical appliance. Conventional ceiling fan is not very efficient. The mechanical
rotation of the fan blade is not fully utilized. The kinetic energy from the rotation of
the fan blade can be capture and converted back to electrical energy. The purpose of
this paper is to describe the development of novel design electrical energy for ceiling
fan that capable of harnessing the waste kinetic energy. Various literature reviews
have been conducted to study the effect of different configuration and parameter such
as blade design, core shape design, relation between number of poles and efficiency
and winding configuration of the electrical machine. For this project permanent
magnet is use as source of excitation. Permanent magnet especially neodymium
magnet (NdFeB) provide high flux density that suit the purpose of motor and
generator. The model is design using AutoCAD to replicate the actual dimensions and
then simulate using finite design element software (Ansys Maxwell) to study the flux
distribution and back EMF characteristic. As for the charger circuit, the design and
simulation is done by using Multism. The charger circuit can give indication when the
battery need to be charge and when the battery is fully charged. The charger circuit is
capable of charging 12V lead acid battery. Based on the results, the ceiling fan model
need to further study to improve the performance and efficiency. After complete the
design simulation the model than will be fabricate and test to determine whether the
actual result is as per the theoretical or not. |
