　　 后來的脈沖被送到計數器，根據脈沖的數目和可測出工作軸的轉角及轉速，其分辨率取決于圓光柵的圈數和測量線路的細分倍數，脈沖編碼器在數控機床上用作位置檢測裝置，將檢測信反饋給數控系統，其反饋給數控系統有兩種方式:一是適應帶加減計數要求的可逆計數器。　　即斷路器斷開時，2P斷路器的零線和火線都斷開了，但是1P斷路器的零線依然沒有斷開。需要注意的是...家庭中能見到的斷路器，一般只有1P和2P的，1P，2P又叫做1級2級，每一級都對應上下兩個接線柱，每一級的寬度是17.5毫米（例如，2P斷路器的寬度為17.5*2=35毫米）。

　　2.電動機是星形(Y)接法：有兩相繞組會燒掉，可以用兆歐表(搖表)測量出兩相繞組對地絕緣破壞。特征：繞組中有一相或兩相（4級）全部變黑，線圈損壞對稱，有規則為缺相。總之：如果電動機是因為缺相而燒掉，那么就會有繞組沒有被燒掉，如果電動機因為負荷過重而燒掉的話就是三相繞組全部對地絕緣破壞。

　　其中稱為串聯電路的等效阻抗。那么，總電壓與電流的位相關系為它亦稱阻抗角。由此可見，串聯電路的總電壓與電流的位相差等于等效阻抗的阻抗角。由于，表示電壓的位相落后于電流，電路呈電容性。2、RL串聯電路以電流為參考矢量，根據電阻、電感元件上的電壓與電流的位相關系畫出串聯電路的矢量圖。

口碑好的韓國電源powerplaza,SPS10-5-12真實性　　對于大容量的直流負載（數A~數十A），必須在實際應用中試驗確認。1.3.3觸點的保護電路：一般感性負載比電阻性負載更容易使觸點受到損傷，如果使用適當的保護電路可以使感性負載對觸點的影響與電阻性負載基本相當，但請注意如果不正確使用，可能會產生反效果。　　所以講空氣斷路器還能在故障狀態(負載短路、負載過電流、低電壓等)下切斷電氣回路。空開只能起到過負荷，短路跳閘。漏電開關在空開的基礎上加裝了一套防漏電裝置，能起到漏電跳閘的作用。起到保護人生及電器設備的。
　　3、有刷電機是產品，性能比較。無刷電機是升級產品，其壽命性能比有刷電機好。但其控制電路比較復雜，對元件的老化篩選要求比較嚴格。5.碳刷電機只能適用于各式洗手間等對要求不是太高的區域，而像無塵車間和防爆車間就無法使用了。

 　　電流互感器二次側不許開路運行。接在電流互感器副線圈上的儀表線圈的阻抗很小，相當于在副線圈短路狀態下運行。互感器副線圈端子上電壓只有幾伏。因而鐵芯中的磁通量是很小的。原線圈磁動勢雖然可達到幾百安或上千安匝或更大。　　3、正弦交流電功率計算公式正弦交流電無功功率計算公式：正弦交流電有功功率計算公式：正弦電流電路中的有功功率、無功功率、和視在功率三者之間是一個直角三角形的關系：當負載為純電阻時，下式成立：此時，直流電功率計算公式同樣適用于正弦交流電路。
