NPM的線性馬達系列為新世代的線性無刷馬達。在需要高可靠度、低維護、無背隙和高精度至關重要的用途時,NPM的線性馬達是最理想的選擇,該產品可以提供無與倫比的性能,易用性、精巧的封裝和高價值給顧客。

What is a Linear Shaft Motor?
管狀線性馬達是一種高精度直驅式直線伺服馬達,由管狀永磁磁鐵(Shaft)和無鐡芯馬達(Forcer)所組成。搭配伺服馬達驅動器進行運動控制。如果您選擇的伺服驅動器支援霍爾元件,可選配內建霍爾元件的Forcer,實現直線馬達的相位檢測。

管狀線性馬達設計有三個基本設計概念:
構造簡單、高精度、非接觸式

管狀線性馬達的構造簡單。由兩部分組成,一個磁軸和一個圓柱繞線圈的Forcer。

管狀線性馬達提供超高精度。在Forcer及Shaft上沒有鐵芯,可適用於高精度及零背隙的用途上。管狀線性馬達的線圈形成核心,可提供比鐵芯馬達還要好的剛性。

管狀線性馬達為非接觸式。由於線圈完全包裹磁鐵,所以可以有效地使用所有磁場。間隙範圍為(0.5至5.0mm)。這意味著當間隙隨裝置的行程變化時,總磁通量是平均的的。

最後,管狀線性馬達的基本結構磁軸上的磁極與磁極間是沒有間隙的,並由不銹鋼管包覆與保護。該過程受到眾多專利的保護。這項專利工藝產生的磁場強度是其他線性馬達的兩倍。
