近年來,隨著生活水平的提升,節約能源與環保意識的高漲,洗衣機已朝向節水、節能、靜音、結構簡單與多功能洗程等方向發展,因此具有高效率、高功率密度、高動態響應與高起動轉矩等優點的直驅式無刷直流馬達在洗衣機市場上逐漸嶄露頭角。本研究針對直驅式洗衣機馬達,設計以低成本、低解析度霍爾位置感測器訊號為基礎的方波換向、弦波換向及弱磁控制(相位超前)技術,並針對市售內藏型稀土磁石與表面黏貼型鐵氧體磁石之直驅式洗衣機馬達進行動力測試,證實本研究各種演算法則的可行性與相關性能。本研究另針對直驅式波輪型洗衣機分別在估測衣物行程、洗衣行程與脫水行程提出一低成本的泛用型控制架構,最後實際在市售洗衣機上進行洗衣實測,並與市售的洗衣機進行比較。實驗結果顯示本研究所設計的速度控制器透過估測轉動慣量建立補償機制,使洗衣速度曲線可以符合洗衣時要求之速度響應,並針對高速脫水後的減速過程提出一種安全,可避免反電動勢電壓回充直流側電容造成損毀的機制,並經由實驗結果證實其可行性。
In recent years, due to the improved living standard, energy saving, and high awareness of environmental protection, the washing machines have been developed on the way to water-saving, energy-saving, noise-free, simple structure, and multifunctional washing process. So, with features such as high efficiency, power density, quick dynamic response, and high starting torque, etc., brushless dc motors are gradually and extensively used in the commercial Direct Drive (DD) washing machines. In this research, a driving technology applying Hall effect position sensors for motors used in DD washing machines is developed. The driving technology uses signals from Hall effect position sensors to do square-wave commutation, sinusoidal commutation, and flux-weakening control (phase advance). The proposed technology is applied to two DD washing machines in the market: one has motor with interior ware earth magnet , while the other has motor with surface ferrite magnet, for dynamic tests. The experimental results demonstrate that the proposed method is feasible and valid. A cost-effective universal control structure is also developed to estimate the quantity of laundry, and to execute washing and spin-dry processes for DD pulsator washing machines. The proposed control structure is implemented and compared with a DD pulsator washing machine available in the market. The experimental result reveals that the dynamic response during washing process is satisfactory. A safe mechanism is introduced and implemented during high speed spin-dry process. The safe mechanism can avoid the failure resulting from charging the DC bus capacitors by the back-EMF voltage.
