Design and modelling of electrical machine for ceiling fan system

The purpose of this research is to conduct an empirical research to design the electrical machine of a ceiling fan system purposely to generate additional electrical power. The conventional single-phase ceiling fan using an induction motor has a lower 30 efficiency. In addition, the wasted kinetic energy from the mechanical rotor rotation can be converted from mechanical energy to electrical energy. Literature review on topologies of an electrical machine, ceiling fan technologies, previous research on ceiling fan and air gap configurations was systematically analyse in order to obtain the optimum proposed designs configuration. In this research, the permanent magnet machine configuration was selected to propose two designs of ceiling fan machine. The newly introduced design concept in this study is the use of concept single rotor double stator that combining the motor and generator in one system. In this research, Finite Element Analysis (FEA) has been performed to justify and to compare the outcome of the proposed designs using the An soft Maxwell software by analysing the induced voltage, flux linkage, flux distribution and air gap flux density. The selected optimized design will be used to develop a prototype for validating the procedure between the simulation result and experimental result. The testing of the prototype will be conducted experimentally to validate the output with the conventional ceiling fan in term of output power, efficiency and speed. © 2006-2015 Asian Research Publishing Network (ARPN).
