Abstract:
The wind speed Malaysia is ranged from 3-7 m/s and most wind turbine requires 5 m/s as cut in speed. Hence, low-energy wind harvesting device is proposed as alternative at this climate. This device is also intended to generate power from vehicle-induced wind. Three potential configurations (electromagnetic, piezoelectric and electrostatic) for small-scale energy harvesting device were proposed by previous researchers and studied in this work. Electromagnetic configuration of energy harvesting by fluttering was selected after analysis of three configurations. A wind belt was designed to withstand environmental conditions such as fresh water (rain), UV radiation and acid/alkali conditions. Several important parameters such as belt width, location of the magnet etc. for the design were evaluated experimentally. Taffeta silk was selected as the belt materials from potential materials. The optimum length and width of the belt in this study are 1 m and 12 mm. Neodymium N45 magnet was selected based on inductance and the optimum magnet position along the belt is 20 cm from the edges of the main frame. Experimental results showed the peak power recorded in parallel connection are 81.02 mW @ 6 m/s with a belt tension of 0.816 N and 24.54 mW @ 4 m/s with belt tension of 0.612 N. The acquired results can be acted as a guide for design of wind belt.
