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

洛倫茲力和安培力并不矛盾，之間可相互推導(dǎo)。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(biāo)量，但有正、負(fù)，正、負(fù) 不代表方向，僅代表磁感線穿入或穿出。同學(xué)們能不能想到其他類似的物理量呢。比如，電流，也是有“運(yùn)動(dòng)方向”的標(biāo)量。

電阻的另一種形式是“膜電阻”，由于繼電器的觸點(diǎn)長期在空氣中，總有灰塵、水汽、化學(xué)氣體產(chǎn)生的化合物，都會(huì)黏附在觸點(diǎn)上形成一層很薄的薄膜，這就是所謂的“膜電阻”；這樣觸點(diǎn)的導(dǎo)電性就很差了，嚴(yán)重時(shí)甚至不導(dǎo)電。

這類電動(dòng)機(jī)的二次繞組中大多串接有離心式啟動(dòng)開關(guān)，正確接線時(shí)，啟動(dòng)電容應(yīng)和離心式開關(guān)串聯(lián)，再和運(yùn)行電容進(jìn)行并聯(lián)。單相雙電容電動(dòng)機(jī)的正確接線方法如圖所示。當(dāng)電動(dòng)機(jī)啟動(dòng)以后，一旦電動(dòng)機(jī)的轉(zhuǎn)速達(dá)到額定轉(zhuǎn)速的80%左右時(shí)，離心開關(guān)的觸點(diǎn)就會(huì)斷開，從而切斷了啟動(dòng)電容與電路的連接，此時(shí)電動(dòng)機(jī)電流減小，電動(dòng)機(jī)進(jìn)入了正常的運(yùn)行狀態(tài)。

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(jì)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(yīng)與理想矩形接近程度的指標(biāo)——矩形系數(shù)（KxdB>1），KxdB=BWxdB/BW3dB，（X可為40dB、30dB、20dB等）。
