減速機(jī)是一種相對精密的機(jī)械，使用它的目的是降低轉(zhuǎn)速，增加轉(zhuǎn)矩。它的種類繁多，型號各異，不同種類有不同的用途分類：
1、按照傳動類型可分為齒輪減速器、蝸桿減速器和行星齒輪減速器；
2、按照傳動級數(shù)不同可分為單級和多級減速器；
3、按照齒輪形狀可分為圓柱齒輪減速器、圓錐齒輪減速器和圓錐－圓柱齒輪減速器；
4、按照傳動的布置形式又可分為展開式、分流式和同軸式減速器。

B：出料成型情況反饋除了要有擠壓模具號碼標(biāo)識清楚的料頭之外，還要在料頭上標(biāo)識料頭難以看出來的整體流向情況，如相交出料（表示在實際擠壓過程中是兩孔內(nèi)側(cè)慢外側(cè)快引起）；相離出料（表示在實際擠壓過程中是兩孔內(nèi)側(cè)快外側(cè)慢引起）；左長右短表示左支長右支短，并且要注明長短相差的量，因為中斷鋸到出料口的距離大約6米，所以通常A米/6米的形式表示長短相差的分量為每6米就相差A(yù)米，這樣完善準(zhǔn)確的表達(dá)才有利于修模人員的正確判斷和維修。

為使交流伺服電機(jī)具有控制信號消失，立即停止轉(zhuǎn)動的功能，把它的轉(zhuǎn)子電阻做得特別大，使它的臨界轉(zhuǎn)差率Sk大于1。在電機(jī)運(yùn)行過程中，如果控制信號降為“零”，勵磁電流仍然存在，氣隙中產(chǎn)生一個脈動磁場，此脈動磁場可視為正向旋轉(zhuǎn)磁場和反向旋轉(zhuǎn)磁場的合成。一旦控制信號消失，氣隙磁場轉(zhuǎn)化為脈動磁場，它可視為正向旋轉(zhuǎn)磁場和反向旋轉(zhuǎn)磁場的合成，電機(jī)即按合成特性曲線運(yùn)行。由于轉(zhuǎn)子的慣性，運(yùn)行點由A點移到B點，此時電動機(jī)產(chǎn)生了一個與轉(zhuǎn)子原來轉(zhuǎn)動方向相反的制動力矩。在負(fù)載力矩和制動力矩的作用下使轉(zhuǎn)子迅速停止。
必須指出，普通的兩相和三相異步電動機(jī)正常情況下都是在對稱狀態(tài)下工作，不對稱運(yùn)行屬于故障狀態(tài)。而交流伺服電機(jī)則可以靠不同程度的不對稱運(yùn)行來達(dá)到控制目的。這是交流伺服電機(jī)在運(yùn)行上與普通異步電動機(jī)的根本區(qū)別。
