http://joe.buckley.net/papers/eddyc.pdf Webb11 nov. 2024 · On one hand, at a low frequency, although the frequency is low, the rotation angle is large. This large angle leads to a higher speed of cutting the magnetic lines in unit time. Therefore, the eddy current damping is large. When the joint is loaded with DC-2 A, the current intensity is small, resulting in a small joint torsional stiffness.
