| Summary: | Air Wheel Generator (AWG) is known as a vertical axis wind turbine with generator for renewable energy have been developed for low and high speed application. Recently, the various shapes of Savonius housing have been studied to improve its rotational speed and coefficient of rotor power. In this paper, Savonius wind turbine with unidirectional Rotor House (RH) for high speed application has been experimental studies to increase the revolution per minute (RPM) of the alternator and charging capability. The experiment on the AWG test stand was set up for different Blade Thickness (BT), t=0.9 mm, 1.2 mm, 1.5 mm, and 2.0 mm where BT that has higher RPM will be the best rotor. The total of 4 test runs of passenger car installed with AWG was conducted using the best BT of the rotor. From the test run conducted on the highway road, the overall functionality of rotor and output voltage have been observed. The apparatus test stand requires verification with actual test run on passenger. On the other word, only the best BT with high RPM will be continued for further test stand for charging capability. Comparison of test stand and test run on passenger car show the blade with a thickness of 0.9mm as the optimum blade thickness. AWG with Blade Guiders had the average speed rated of the alternator is 600 RPM (V belt) and 400 RPM (V Ribbed belt) as a switch is on for air speeds varies from 22.22 to 32.8 m/s. The standard Permanent Magnet Direct Current (PMDC) generator with the same average speed rate was proposed as good combinations for AWG with uni-directional RH. Hence, the conversion of car alternator as the standard permanent magnet that has water proof that may be used also with wind nozzle and lighter rotor material to increase the torque and power of the rotor in the future. |
