齒輪傳動系統在工業上已被廣泛的使用，因機械齒輪具有成本低及扭矩傳遞大的特性，然而產業對傳動系統之精密度及維修保養的要求日益提升。本文利用同心式磁性齒輪磁性非接觸式傳動之特性改善現有接觸式車窗傳動系統的缺點，是天生具有過載保護功能，無須保護電路及可達自我防夾之安全性設計，減少損耗及維修保養次數之優勢。
本文探討可一體式磁環充磁，具有極異方特性及偏斜磁極，且應用軟磁3D列印技術，列印新構型充磁座樣本，製作充磁耗能低的斜槽充磁座，以相同充磁電流匝數條件下，新構型充磁座充磁產生之磁通密度較傳統矽鋼片充磁座高出53%，最終將充磁後之磁環應用於同心式磁性齒輪，達到可降低36%頓轉扭矩之設計，並以實作結果進行驗證

Gear transmission system has been widely used in industry for its mechanical gears possessing the characteristics of low cost and large torque transmission. However, the industry's requirements on the precision and maintenance of the transmission system are increasing day by day.
This research investigated the integrated magnetic ring that could be magnetized, had the characteristics of polar anisotropy and skewed magnetic poles, and manufac-tured based on soft magnetic 3D printing technology. A new configurated sample of a skewed magnetization fixture is formed by 3D printing, which is featured with low magnetizing energy consumption. Under the condition of the same number of magnet-izing current turns, after magnetizing, the magnetic flux density of the new configur-ated magnetization fixture was 53% higher than that of the traditional silicon steel sheet one. Then, the magnetized magnetic ring was applied to the concentric magnetic gear to achieve a design that could reduce the torque by 36%, and finally the proposed design was further verified with experimental results
