為了優化馬達效率,儘管要根據來自霍爾傳感器的轉子位置信息來控制超前角,但必須使用實際設備來調節超前角。
即使馬達控制器/驅動器具有自動超前角控制功能,超前角也必需根據馬達常數,rpm和其他因素進行調整。因此,需要一種減輕用戶負擔的改進的控制方法。
智能相位控制可檢測馬達電流相位,並反饋信息以進行自動超前角控制。當馬達應用中帶有感測器時,霍爾信號的相位會自動調整以匹配馬達驅動電流的相位。
無論馬達的rpm,負載轉矩和電源電壓如何,都能實現高效率。智能相位控制還有助於減少調整導程角所需的外部零件數量。
減少了超前角控制所需的外部組件數量,並且無需根據電動機的運行狀態變化進行任何編程
為了滿足市場需求,東芝開發了智能相位控制,以響應不斷發展的社會和技術趨勢。智能相位控制無需複雜的調整即可使用。東芝提供了廣泛的BLDC馬達驅動控制器產品組合,它們具有適合各種需求的智能相位控制。如果要使用集成了智能相位控制的BLDC馬達評估產品計劃或設計,可以下載參考設計。
