本研究之目的在於設計一個新型的軸向式磁性聯軸器，再設計兩個測試台
分別量測磁性聯軸器之軸向磁力與傳輸扭矩，並應用有限元素法進行電腦模
擬，再與實驗值作比較分析。亦針對本研究所設計的磁性聯軸器於裝配時所產
生的誤差現象，進行其對傳輸扭矩及磁力的影響分析，以期能達到對此磁性聯
軸器使用特性上有更深一層的瞭解。結果顯示，使用有限元素法分析軸向磁
力、扭矩、滑差角與磁極間距的關係值，其與實驗值的誤差值皆在10% 內。
本研究所設計的磁性聯軸器之傳輸效率皆在92% 以上，且在磁極間隙相同的
條件下，傳輸扭矩愈大，效率愈高。另外，磁性聯軸器軸中心的徑向偏移愈大，
最大傳輸扭矩與最大軸向磁力愈小，在相同的徑向偏移條件下，滑差角愈小，
傳輸扭矩及軸向磁力減少率愈大。磁性聯軸器軸中心的角向偏移愈大，最大傳
輸扭矩愈大，合力愈大。

The purposes of this study are to design two test rigs for measuring the
axial magnetic force and transmission torque of a novel magnetic coupling.
Using the finite element method (FEM) illustrates the characteristics of the
novel magnetic coupling, and then we compare simulation results with experimental
values. Moreover, the effect of misalignment on transmission
torque and magnetic force of magnetic coupling designed for this research
was explored in order to obtain the influence of assembly parameters. The
results reveal that when FEM was used to analyze the correlations among
the axial magnetic force, torque, slip angle and pole distance, the maximum
error between the simulation value and the experimental value was within
10%. The magnetic coupling designed for this research has a transmission
efficiency above 92%. With the same magnetic pole gap, the greater the
external torque is, the higher the transmission efficiency is. In addition, the
greater the radial displacement is, the smaller the maximum transmission
torque and maximum axial magnetic force are. With the same radial displacement,
the smaller the slip angle is, the greater the reduction rate of the
transmission torque and the axial magnetic force are. The greater the angular
displacement is, the greater the maximum transmission torque and
magnetic force are.
