Wind Energy Harvesting

August 11 – 18 2009

Experiment 1: Measuring the Wind Speed

FAN SPEED Actual Wind Speed

1 4.37 m/s

2 4.98 m/s

3 5.59 m/s

DATA

This experiment was done by using the

simple anemometer provided by Sir

Opus. The electric fan measured is the one situated in the

workshop.

Fan Speed Voltage (AC) Current

1 3.2 V 2.05 mA

2 4.4 V 25 mA

3 5.05 V 25 mA

Experiment 2: Measuring Voltage and Current

DATA

This experiment was done using the department electric fan situated at the department workshop . The pictures of

the set-up for both the voltage and current measurements will be provided in the next slides. The video coverage

will also be shown.

At a fan speed of 1 which is

approximately having a wind speed of 4.37

m/s. The device can

slightly turn a light bulb on.

Experiment 3: Motor Testing

Motor 1: AirPAx MotorVoltage Generated: 10.4 V

AC The motor has a red and black physical color

characteristic. It is slightly harder to turn as compared to the other motor tested. This motor tested at the

department using the drill at the uniform drill speed.

Motor 2: Teac MotorVoltage Generated: 11.33 V AC The motor’s rotor

component runs smoothly under the experiment

conditions. This motor is run using the same set-up as the first motor. The drill used to test the motor also runs at a uniform speed.
