NdFeB magnets in wind energy system: A review of innovations for enhanced energy efficiency in Indonesia

Indoensia faces significant challenges due to its reliance on fossil fuels, which contribute to high greenhouse gas emissions. To mitigate this issue, Indonesia is actively investigating renewable energy alternatives, such as wind power, despite conditions with typically low wind speeds. This study explores the potential application of NdFeB (Neodymium Iron Boron) permanent magnets in wind turbine generators, aiming to enhance efficiency and minimize environmental impacts. NdFeB magnets provide significant coercivity and energy density, which can improve generator performance in low-wind conditions. This paper examines various synthesis methods for NdFeB magnets, including powder metallurgy and melt-spinning, while also exploring their applications and advantages in wind turbines. Challenges such as dependence on rare earth elements, corrosion, and material expenses are also investigated. By investing in advanced magnet technology and renewable infrastructure, Indonesia has the potential to enhance its wind energy capacity, contributing to the long-term sustainability goals and supporting industrial development in green energy.
