Construction Of Electricity Generator Using DC Motors With Coils

1.0 INTRODUCTION
1.1 BACKGROUND OF THE PROJECT
For the past decades, world’s main concerns are energy and environment. Demands in finding alternative source of energy as an answer to the dwindling energy sources has become one of the top priorities in the field of science and technology. More than 90% of the world’s generated power uses electromagnets based on faraday’s law of electro-magnetic induction. Thus, interests in Free Energy/Electricity become popular.

The concept of Free Energy/Electricity is a misconception. There is no such thing as free energy. However, if we generate it thru the means of readily available resources such as the Sun, Wind, Tidal, Hydro-electric, Geothermal is only free after the initial capital cost. The energy generated becomes free after the point that we don’t have to pay for the generation of the electric power produced by these non-conventional methods of generating electrical power.

Hence, the concept of generating electricity using magnets has been around us for some time. Their magnetic fields are used to produce electrical power. These magnets are placed in the cores of motors and generators. Power generation’s basic principle lies on the magnetic effect. It states that “when a conductor is rotated in a magnetic field, a voltage is induced in the conductor”. This study will be dealing with such conductors.

This work made the researcher to come up with the idea of Electromagnetic Induction means. With the use of DC motor and magnets, this study intends to devise a generator that will generate usable amount of electricity.

In this study, a brushless motor is used as a generator. Brushless DC motors were developed from conventional brushed DC motors with the availability of solid state power semiconductors. Brushless DC motors are similar to AC synchronous motors. The major difference is that synchronous motors develop a sinusoidal back EMF, as compared to a rectangular, or trapezoidal, back EMF for brushless DC motors. Both have stator created rotating magnetic fields producing torque in a magnetic rotor. Synchronous motors are usually large multi-kilowatt size, often with electromagnet rotors. True synchronous motors are considered to be single speed, submultiples of the power line frequency. Brushless DC motors tend to be small– a few watts to tens of watts, with permanent magnet rotors. The speed of a brushless DC motor is not fixed unless driven by a phased locked loop slaved to a reference frequency.

1.2 PROBLEM STATEMENT
In the past, energy generation depends fully on fossil fuels which produces carbon monoxide and also have higher cost power generation bill. Because of these disadvantages, researchers came out with free energy generation. Free energy sources of energy are now a major concern worldwide as replacement to the high demand of fossil fuels. This energy becomes free only at a point after which we don’t have to pay for power generation after commissioning the unit. By using the magnetic force of magnets continuous motion (Energy) is generated.

We used Neodymium magnets are placed on the fins of the fan (dc motor). Disc shaped magnets are placed in such a way that all the north poles or south poles are facing one direction. This magnet also produces a magnetic field, so both the magnetic fields repel each other (like poles repel), which causes the fins to move, and thereby generating electricity.
