Overview of permanent magnet wind power generators

Abstract

With the advancement of renewable energy technologies and the increasing emphasis on environmental issues, wind power generation systems have experienced rapid development. Permanent-magnet (PM) machines have been widely favored in the generator domain due to their high torque density, high reliability, and high efficiency. This article provides a detailed review of PM machines applied in wind power generation systems, categorizing the types of machines based on the number of mechanical and electrical ports (EPs). This article emphasizes the generator topologies, operational principles, and performance characteristics, while also comparing the advantages and disadvantages of different structures. Furthermore, this article discusses the current challenges faced by PM wind generators and outlines future development trends.
