A Novel Design of Ceiling Fan System

There are many electrical appliances used in every house. One of them is the ceiling fan where it consumes between 70 to 90 Watts of electrical energy. This makes it the second highest appliance to consume electricity. The conventional ceiling fan is designed based on induction machine. However, the induction machine is not very efficient. Another weakness of the conventional ceiling fan is that it does not fully utilize the rotating part in it. This paper aims to use the rotating part in the ceiling fan to regenerate electricity to be used in other household appliances. This concept uses the basic design of the internal and external rotor which is to be used to build the system. Thus, this design could help to reduce energy consumption and making the ceiling fan more efficient compared to the conventional ceiling fan. The literature review in this paper is done to study the various types of machines which could be selected to be used in designing the new type of ceiling fan. Such machines are the induction machine, synchronous machine, the DC machine and the permanent magnet. The proposed design for the motor and generator are determined after the comparison had been done between all the designs. The proposed design is simulated and analyzed using the finite element software, ANSYS software, ANSOFT MAXWELL. The results obtained from the simulation are in term of the flux distribution and the air gap distribution. After analyzing the result, it is found that the design chosen proved to be working successfully.
