Vertical Axis Wind Turbine (VAWT) is a type of important electric equipment. A hybrid maglev supporting structure in shaft system of VAWT is mentioned in this paper. The simulation has been conducted to study the magnetic field and force on this structure. The working condition is classified by four different length and magnetic isolated condition, three kinds of exciting currents compound modes is studied at the same time. Through the contrastive analysis of ANSYS simulation, the computed results reveal that the magnetism of pole terminals need to be isolated and face-to-face or back-to-back excitation is appropriate for magnet units in differential mode. The magnetic field and magnetic force are also emulated when the rotor working the position of equilibrium.
