DEVELOPMENT OF MICRO AIR FLOW GENERATOR FOR ELECTRICAL CHARGING SYSTEM

The need for electrical energy nowadays is high. As technology becomes advanced in certain areas, the ability to produce power has had to keep pace with the increasing of demands. There is a tremendous amount of free energy in the air or wind which is available for energy conversion. The use of wind machines to harness the energy in the wind is not a new concept. The early machines were used for pumping water for irrigation purposes and later developed as windmills for grinding grain. The power in the wind at any moment is the result of a mass of air moving at speed in a particular direction. Thus, the electric power generation technology these days being highly develop. Since motorcycles are the main vehicle used in Malaysia, a charging device is not available compare to cars which have a cigarette port as charging port. Aware on free energy produced by air flow in the motorcycle exhaust, it can be utilized to produce electricity. Having a concept of wind generator, this air flow energy can be exploited. Therefore, the aim of this project is to generate electricity through the conversion of wind energy to electrical energy. The methods used are to develop a turbine for energy harvester, a DC generator for electrical generation and an electrical circuit to boost the output produced by the generator. The air flow is being converted into kinetic energy by the rotation of a turbine. Attached to the turbine is the shaft and directly into the DC motor. Inside the motor, there are two main components which are permanent magnet (stator) and winding (rotor). The rotation of the shaft makes the rotor move and then the motor will react as the generator. From these consequences, the generation of electricity energy can be produced. Then, prototype being developed consists of the turbine, the casing of the turbine, DC generator and electrical circuit. Several testing then being conducted to see the performances and output of the prototype. By having a rechargeable battery, electrical energy can be stored. Target of this prototype is to produce SV for charging purpose. This electrical energy then can be used for any type of application, such as charging the hand phone, mp3 player and even digital camera
