Abstract

INTRODUCTION

The Philippines is visited by an average of 19 typhoons annually and during these calamities, we often experience electrical shut down for safety purposes. With this scenario, where typhoon occurs during night time, people are immobilized because of darkness in the surroundings, making everybody unable to move to safer ground. The use of solar panels is much recommended but due to its cost, an ordinary family cannot afford to own one. The assembly using the motor of an electric fan and powered by the wind speed of at least 30 kph can be used to light a 3 watt LED bulb. This can be used specifically during typhoons.

METHODS

The experimental method was used in the assembly of the project. The ventilation motor of a ceiling fan is a single phase induction motor that has a similar component with that of a generator. The electric motor of an electric fan (3 phase motor) was replaced and modified to become a single phase motor. The resulting motor was used both as a fan (when connected to AC) and a power source (when exposed to a wind speed of at least 30kph) that can light up a 3 watt LED bulb.

RESULTS

The assembly is of dual purpose. Since it reverses the function of a single phase motor, it is used as a fan when plugged to AC current, and when unplugged and exposed to a wind speed of 30 kph, it is a source of power that is enough to light a 3 watt LED bulb. The latter is used during typhoons when electricity is shut down and the source of light is inevitable. When unplugged and exposed to a 30 kph wind speed, it can generate an electric current of 100 Volts enough to light a 3 watt LED bulb which is sufficient to light a dark place in times of typhoons.

DISCUSSIONS

The single phase motor connected to a stand fan and with some modifications on its connections functions as a regular electric fan when connected to AC and a generator when power is out. As a generator, it generates electric current when exposed to a minimum of 30 kph wind speed enough to light a bulb. The converted fan is easily assembled and recyclable materials can be used.
