A novel magnetic levitated bearing system for Vertical Axis Wind Turbines (VAWT)

Applied Energy, 2012
Abstract In this report, a novel magnetic levitated bearing suitable for Vertical Axis Wind Turbines (VAWT) is introduced, fabricated and tested. The bearing system generates a magnetic force, which can support the weight of the wind turbine rotor. A Finite Element Method (FEM) simulation shows how low the torque of this bearing is.
