Outline of Final Research Achievements

In this study, I develop the output improvement mechanism of the vertical axis small wind power generator. In this study, I clarified the effectiveness of two mechanism to show next.
The first is the mechanism that incorporated a noncircular gear to reduce cogging torque of the motor for generators. Some noncircular gear reduced more than 25 % of torque as a result.
The second is the continuously variable transmission mechanism that is mechanical to control in a centrifugal governor. As a result, the output improved this continuously variable transmission mechanism more than 15% in comparison with step-up gear of the gear ratio uniformity. In addition, from this improvement study, I was able to devise the continuously variable transmission of a new method.
