In this paper, a rigorous and efficient approach, using the fuzzy-Inference Taguchi method with the multiple performance characteristics index (MPCI), is employed for obtaining the rigorous design of a small-scale direct-drive coreless axial-flux permanent-magnet (AFPM) generator for a vertical-axis wind turbine (VAWT) with both larger induced voltage and higher efficiency. The proposed method first establishes the orthogonal array (OA) recommended by the Taguchi method, then multiple targets are coordinated by the fuzzy inference mechanism to obtain a better combination of geometric parameters for achieving multiple quality targets. The three-dimensional (3-D) electromagnetic finite element method (FEM) is used as the tool for analyzing the performance of the coreless AFPM generator. The results have shown the proposed method can obtain the suitable generators geometric parameters for enhancing the induced voltage of the generator while keeping efficiency as high as possible under the rated speed.

AbstractThere is growing need for the green, reliable, and cost-effective power solution for the expanding wireless microelectronic devices. In many scenarios, these needs can be met through a small-scale wind energy portable turbine (SWEPT) that operates near ground level where wind speed is of the order of few meters per second. SWEPT is a three-bladed, 40 cm rotor diameter, direct-drive, horizontal-axis wind turbine that has very low cut-in wind speed of 1.7 m/s. It operates in a wide range of wind speeds between 1.7 m/s and 10 m/s and produces rated power output of 1 W at wind speed of 4.0 m/s. The wind turbine is capable of producing electrical power up to 9.8 W at wind speed of 10 m/s. The maximum efficiency of SWEPT was found to be around 21% which makes it one of the most efficient wind turbines reported at the small scale and low wind speed. These advancements open many new opportunities for embedding and utilizing wireless and portable devices.
