Abstract

Renewable, unlimited and environmentally safe, wind energy is referred to as renewable energy. In Indonesia, wind speeds between 3 to 7 m/s are considered moderate wind speeds. Wind turbines can be used to convert wind energy into electrical energy. The Savonius rotor is cylindrical and has two or more blades attached. The purpose of this study is to determine the power, torque, and rotation per minute produced by a Savonius rotor wind turbine with a blade radius of 50 cm and a blade height of 100 cm. Wind speeds of 3 m/s, 5 m/s, 7 m/s, 9 m/s, 11 m/s, 13 m/s, and 15 m/s were used for testing. A tachometer was used to measure rpm, while a loadcell sensor measured torque and power data. Based on the research findings, it was found that each wind speed variation produced a different average rotor rotation per minute. The rotor speed, torque, and power increased with increasing wind speed.
