碩士電機工程學系[[abstract]]本論文為環型多極磁石充磁座的磁路模擬分析與設計，使磁石在徑向充磁前，計算及模擬磁鐵的磁力線及磁通量。在考量磁性材料特性與低成本的要求之下，根據充磁時間的控制與電流的限制，模擬充磁座的工作條件，開發符合傳送機的磁耦合扭力要求之環型多極磁石，進而改善其生產品質，縮短開發時程，降低生產成本。最後經由實驗驗證所設計之徑向充磁座的工作條件，找出適當的充磁電流範圍於10kA~13kA之間，及充磁座與磁石氣隙的距離0.5- 1 mm的範圍內，便可使得環型多極磁石獲得飽和的磁通密度。 關鍵字：磁性耦合扭力、徑向斜角充磁、充磁座。[[abstract]]This study is to simulate and design the magnetic circuit of the annular type multiple magnetizing fixture. The purpose aims to calculate and draw the lines of magnetic force and the magnetic flux before the magnet is magnetized. With the consideration of low-cost magnetic material property , the simulation of magnetizing fixture is performed under the control of magnetizing period and current limitation. Such design could meet the requirement of magnetic coupling torque, improve the magnetizing quality, reduce the developing period, and lower the cost. The experimental resets show that the appropriate magnetizing current is between 10kA and 13kA and the air gap inside the fixture is in the range of 0.5 ~ 1 mm in which the annular type multiple magnetizing fixture can obtain a saturated magnetic flux. Key word: magnetic coupling torque, radial oblique angle magnetizing, and magnetizing fixture
