| description | The invention provides a double-stator hybrid excitation eddy current damping device. The device is of a hollow structure, and includes an outer stator, a rotor and an inner stator. The outer stator is fixed on an outer support base and includes a plurality of core teeth and excitation windings wound on the core teeth, and the slots between adjacent core teeth are sealed by first permanent magnets. The inner stator is fixed on an inner support base and includes a plurality of core teeth and excitation windings wound on the core teeth, and the slots between adjacent core teeth is sealed by second permanent magnets. The eddy current damping device is light, and the air gap magnetic field is produced by the excitation windings and the permanent magnets together, so that the air gap magnetic field provided has large amplitude and is adjustable and efficient. When the rotor is preferably arranged in a copper-steel-copper structure, the radial air gap flux density and conductivity can be further improved, and a gre |
