Systems to control the rotational speed of a Savonius-type wind turbine and to allow the Savonius rotor to stop the rotation in a strong wind are presented. It is known that the performances of a Savonius rotor changes greatly by varying the location of a deflecting plate which is placed in front of the rotor. The output of the rotor increases when the deflecting plate is located at an optimum place, while the rotor torque becomes nearly zero when the plate is located just in front of the rotor. Hence, in this work, the rotational speed of the Savonius rotor is controlled by turning the deflecting plate around the rotor. As the device to let the deflecting plate turn around the rotor, tail wings are used at first, and then, electronic devices, that is, an A/D converter, personal computer and a stepping motor are applied to control the rotational speed of the rotor more precisely than the control by the tail wings.
