Abstract
Inductive levitation improves the performance and durability of Vertical Axis Wind Turbines (VAWTs) by minimizing mechanical contact and energy losses. This study examines the usage of a Cylindrical Induction Levitator (CIL) in a VAWT system and develops an analytical model of its electromagnetic behavior. Magnetic circuit parameters, flux distribution, and inductance characteristics were calculated to ensure stable levitation and a uniform magnetic field in the air gap. The results demonstrate that the proposed configuration permits effective counterbalance of gravitational forces through electromagnetic lifting, minimizing friction and mechanical wear in the rotor system. The specific magnetic permeability of the air gap depended on the C/R ratio, decreasing as the ratio increased. This significantly affects levitation performance and system efficiency. Additionally, maintaining magnetic induction below saturation levels in ferromagnetic components ensures stable operation and improved reliability. These findings confirm that inductive levitation can enhance operational efficiency, reduce maintenance requirements, and extend the service life of VAWTs.
