Two stator mixed excitation eddy current damping devices

The utility model provides a two stator mixed excitation eddy current damping devices, the device are hollow structure, including external stator, rotor and internal stator, the external stator is fixed outside on the supporting seat, and including several iron core tooth and the excitation winding on each iron core tooth of detouring, the notch between the adjacent iron core tooth is sealed by first permanent magnet each other, including the internal stator is fixed on the supporting seat, including several iron core tooth and the excitation winding on each iron core tooth of detouring, the notch between the adjacent iron core tooth is sealed by the second permanent magnet each other. This eddy current damping device quality is light, and the air gap field is produced by excitation winding and permanent magnet jointly, and the air gap field amplitude that consequently can provide is big, adjustable, efficient. When the preferred adoption copper of rotor the steel when the steel structure is arranged, radial
