，電機(jī)還要有更強(qiáng)壯的結(jié)構(gòu)，扭矩的增大正比于控制電流的增大，此時(shí)采用比較大的驅(qū)動(dòng)器，功率電子組件和相關(guān)機(jī)電設(shè)備規(guī)格的增大，又會(huì)使控制系統(tǒng)的成本大幅增加。據(jù)了解，負(fù)載慣量的不當(dāng)匹配,是伺服控制不穩(wěn)定的較大原因之一。對(duì)于大的負(fù)載慣量，可以利用減速比的平方反比來(lái)調(diào)配較佳的等效負(fù)載慣量，以獲得較佳的控制響應(yīng)。所以從這個(gè)角度來(lái)看，行星減速機(jī)為伺服應(yīng)用的控制響應(yīng)的較佳匹配。從成本觀點(diǎn)，假設(shè)0.4KW的AC異步伺服電機(jī)搭配驅(qū)動(dòng)器，需耗費(fèi)一單位設(shè)備成本,以5KW的AC異步伺服電機(jī)搭配伺服驅(qū)動(dòng)器必須耗費(fèi)15單位成本，但是若采用0.4KW異步伺服電機(jī)與驅(qū)動(dòng)器，搭配一組減速機(jī)就能夠達(dá)到前述耗費(fèi)15個(gè)單位成本才能完成的事，在操作成本上節(jié)省50%以上。</p><p

1.8°、0.9°，五相混合式異步伺服電機(jī)步距角一般為0.72 °、0.36°。也有一些高性能的異步伺服電機(jī)通過(guò)細(xì)分后步距角更小。如三洋公司（SANYO
