　　上圖電路就是星三角降壓啟動的主回路。這里面要說一下，多大功率的電動機要用降壓啟動呢。有好多朋友說7.5KW以上就要降壓啟動，也有說11KW的，還有說15KW的。還有的朋友說，他們廠的55KW的電機還是直接啟動呢。那么哪個是對的呢。

　　洛倫茲力和安培力并不矛盾，之間可相互推導。安培力和洛倫茲力的方向，都是通過左手定則來判定的。磁通量是標量，但有正、負，正、負 不代表方向，僅代表磁感線穿入或穿出。同學們能不能想到其他類似的物理量呢。比如，電流，也是有“運動方向”的標量。

　　電阻的另一種形式是“膜電阻”，由于繼電器的觸點長期在空氣中，總有灰塵、水汽、化學氣體產生的化合物，都會黏附在觸點上形成一層很薄的薄膜，這就是所謂的“膜電阻”；這樣觸點的導電性就很差了，嚴重時甚至不導電。

　　這類電動機的二次繞組中大多串接有離心式啟動開關，正確接線時，啟動電容應和離心式開關串聯，再和運行電容進行并聯。單相雙電容電動機的正確接線方法如圖所示。當電動機啟動以后，一旦電動機的轉速達到額定轉速的80%左右時，離心開關的觸點就會斷開，從而切斷了啟動電容與電路的連接，此時電動機電流減小，電動機進入了正常的運行狀態。

　　通常有兩種提法：一種為要求對某一給定帶外頻率fs抑制多少dB，計算方法為fs處衰減量As-IL；另一種為提出表征濾波器幅頻響應與理想矩形接近程度的指標——矩形系數（KxdB>1），KxdB=BWxdB/BW3dB，（X可為40dB、30dB、20dB等）。

 　　2.控制回路采用24V作為額定控制電壓時，應采用并聯型觸點，以其工作可靠性。3.控制回路必須用低電壓控制時，以采用48V為優。大容量器可利用中間繼電器控制，以進一步工作可靠性。4.控制回路采用220V及以上電壓作為額定控制電壓時，具有高的可靠性。　　 扁孔的，兩頭的，三角的,大家在日常生活中使用的插線板大多是這類產品，不同類型的開關主要區別于它們的面板尺寸和設計，而家居電路安裝一般以86型和118型開關為主，SOK開關都有這兩型，各有所長，建議消費者同時選購。
