Magnetic suspended wind turbine generator is widely studied due to its low loss, low maintenance cost and high reliability. However, affected by the small stiffness of magnetic bearing, the generator shaft supported by magnetic bearing will be eccentric. Therefore, the performance of generator will be affected. A horizontal axial magnetic suspended wind turbine generator is designed in this paper. The variations of shaft eccentricity and Maxwell force of rotor supported by different bearing stiffness are studied. The results show that the shaft eccentricity affects the performance of generator; and the bearing stiffness is the key to reduce those effects. The magnetic bearing designed in this paper can meet the requirements of generator.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
