| dc.description.abstract | 本篇論文欲設計一個創新的手輪馬達，並將此應用於電動輪椅。不同於傳統的電動輪椅，利用高轉速的馬達搭配減速機構；手輪馬達採直接驅動，不需要減速機構，使得空間可以有效利用，重量大幅降低。手輪馬達不僅是一個馬達，亦有手扶圈的功用，而且轉子就是手扶圈，施力半徑大，力矩與力矩密度高。
本文先對電動輪椅的行駛條件作性能估測，並決定馬達的性能規格，將馬達作靈敏度分析後，再利用最佳化軟體搜尋最佳尺寸，並使用有限元素分析軟體驗證與尺寸修改，期望降低力矩漣波與齒卡力矩。最後將本文設計的馬達作性能測試，並與模擬比較驗證 | zh_TW |
| dc.description.abstract | The traditional electric wheelchairs are equipped with a high speed motor and reduction gears. In general, the structure is space-unefficient and weight-overloded. So the thesis suggests an innovative rim motor for electric wheelchairs. A target of our paper is to design a direct-drive rim motor having high torque without the additional equipment. The novel device could be used to be not only a motor rotor but a hand-rim. This motor has high power, torque, torque density and low weight.
First of all, we should determine the torque, speed and power based on dynamic evaluation. Second, the sensitivity analysis and optimal search method would be used. Ultimately, the optimal results would be demonstrated by the Finite-Element-Method Analysis (FEMA). Moreover, we would modify the detail dimension to eliminate the cogging torque and torque ripple. The simulation results would be eventually compared with experiments. | en |
