The eddy current damper applied to the first-order vibration reduction of the wind turbine can effectively reduce the first-order vibration acceleration, reduce the load and fatigue of the wind turbine, improve the service life and reduce the cost of the wind turbine.
Through the superposition of two 90° vertical bearing guide mechanisms, two degrees of freedom in the plane can be provided to the vibrator, and the structural energy consumption relies on the vibrator moving in the plane to cut the magnetic inductance lines.

The double slides damper is suitable for vertical installation on wind turbine parts with small installation space, such as yaw platforms, nacelle interior and top of nacelle.
