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.
