PARKER派克電磁閥PHS530E-03-24V-FL 3/8顯然不可取。為此，人們往往需要配備限制電機起動電流的起動設備，過去人們多采用Y/△轉換，自藕降壓，磁控降壓等方式來實現。這些方法雖然可以起到一定的限流作用，但沒有從根本上解決問題。伴隨傳動控制對自動化要求的不斷提高，采用可控硅為主要器件、單片機為控制核心的智能型電動機起動設備－軟起動器，已在各行各業得到越來越多的應用，由于軟起動器性能優良、體積小、重量輕，并且具有智能控制及多種保護功能，而且各項起動參數可根據不同負載進行調整，其負載適應性很強。因此電子式軟起動器將逐步取代落后的Y/Δ、自耦減壓和磁控式等傳統的減壓起動設備成為必然。電力電子技術的快速發展，智能型軟起動器得到廣泛應用。智能型軟起動器是一種集軟起動、軟停車、輕載節能和多功能保護于一體的新穎電機控制裝置。

總之，只有了解用戶、了解任務才能設計出好的人機界面。確定為完成此系統功能人和計算機應分別完成的任務任務分析有兩種途徑。一種是從實際出發，通過對原有處于手工或半手工狀態下的應用系統的剖析，將其映射為在人機界面上執行的一組類似的任務；另一種是通過研究系統的需求規格說明，導出一組與用戶模型和系統假想相協調的用戶任務。逐步求精和面向對象分析等技術同樣適用于任務分析。逐步求精技術可把任務不斷劃分為子任務，直至對每個任務的要求都十分清楚；而采用面向對象分析技術可識別出與應用有關的所有客觀的對象以及與對象關聯的動作。考慮界面設計中的典型問題設計任何一個機界面，一般必須考慮系統響應時間、用戶求助機制、錯誤信息處理和命令方式四個方面。
