<br/><br/> This study focuses on the development of a small-scale wind turbine designed specifically<br/>for low wind speed areas, utilizing a dual-rotor axial flux generator. The primary objective<br/>is to create an efficient energy-generation system by combining magnetic levitation and<br/>advanced flux management techniques. The system employs magnetic bowls, where<br/>magnets repel each other and are tilted at seventy degrees to stabilize and lift the rotor,<br/>enabling frictionless operation. For the dual-rotor generator, a Halbach array configuration<br/>is used to enhance magnetic flux density, reduce flux leakage, and concentrate the magnetic<br/>field within the coils to maximize energy harnessing.<br/>The results demonstrate that magnetic levitation significantly increases the rotor's<br/>revolutions per minute compared to traditional bearing systems, while also reducing<br/>friction. Furthermore, the Halbach array configuration enhances the flux density by<br/>threefold and increases the effective height of the magnetic field, leading to improved<br/>power output.<br/>A wind assessment conducted at Cupang Senior High School in Muntinlupa City, near<br/>Laguna de Bay, confirmed the suitability of the site’s low-speed, onshore wind conditions<br/>for small-scale turbine deployment. CFD analysis using SimScale showed that the<br/><br/>Conventional Savonius blade design outperformed the Ice blade design in terms of low-<br/>speed performance. FEA further verified the effectiveness of the Halbach array in<br/><br/>enhancing magnetic field strength and generator performance, especially at smaller air<br/>gaps. These findings support the DAHAPMSG system’s viability as a reliable, efficient<br/>renewable energy solution for low-wind, urban environments.
