damping coil 阻尼線圈。

As a result , the electromagnetic field intensity is changed accordingly and fluctuating current in the damper coil is created . damping force is mostly produced because of the phase difference between fluctuating current and displacement of rotor . the formulas of fluctuating current and damping coefficient are deduced theoretically , and the calculated results are consistent with the experimental results 通過分析發現電磁阻尼器線圈內由于轉子渦動時變化的磁場而產生的波動電流與轉子位移間的相位差是產生阻尼的主要原因,推導了波動電流、阻尼系數的計算公式,并通過實驗展示了被動式電磁阻尼器的阻尼效應。
