分類和特點
1．異步型交流伺服電動機
異步型交流伺服電動機指的是交流感應(yīng)電動機。它有三相和單相之分，也有鼠籠式和線繞式，通常多用鼠籠式三相感應(yīng)電動機。其結(jié)構(gòu)簡單，與同容量的直流電動機相比，質(zhì)量輕1/2，價格僅為直流電動機的1/3。缺點是不能經(jīng)濟地實現(xiàn)范圍很廣的平滑調(diào)速，必須從電網(wǎng)吸收滯后的勵磁電流。因而令電網(wǎng)功率因數(shù)變壞。
這種鼠籠轉(zhuǎn)子的異步型交流伺服電動機簡稱為異步型交流伺服電動機，用IM表示。

下面對采用DIN標(biāo)準(zhǔn)和ISO標(biāo)準(zhǔn)的HSK刀柄的定位精度和聯(lián)接剛度作一對比分析。定位精度HSK刀柄的定位精度包括軸向定位精度和徑向定位精度。由于采用DIN標(biāo)準(zhǔn)和ISO標(biāo)準(zhǔn)的HSK刀柄均利用端面進行軸向定位，因此二者都具有很高的軸向定位精度(.1mm)，不存在差異。由于HSK刀柄利用錐面實現(xiàn)徑向定心，因此其徑向定位精度由HSK刀柄錐面大端與主軸錐孔大端的配合狀況決定。以HSK-A63型刀柄與主軸為例，按DIN標(biāo)準(zhǔn)進行制造時，大端處的平均過盈量為8Micro;m而按ISO標(biāo)準(zhǔn)進行制造時，大端處的平均過盈量為12Micro;m。

減速機在原動機和工作機或執(zhí)行機構(gòu)之間起匹配轉(zhuǎn)速和傳遞轉(zhuǎn)矩的作用，隨即由我國上海長城減速機器廠礦減速機理運用全新技術(shù)革新的減速機一般用于低轉(zhuǎn)速大扭矩的傳動設(shè)備
減速機一般用于低轉(zhuǎn)速大扭矩的傳動設(shè)備，把電動機、內(nèi)燃機或其它高速運轉(zhuǎn)的動力通過減速機的輸入軸上的齒數(shù)少的齒輪嚙合輸出軸上的大齒輪來達到減速的目的，普通的減速機也會有幾對相同原理齒輪達到理想的減果，大小齒輪的齒數(shù)之比，就是傳動比。
蝸輪蝸桿減速機的主要特點是具有反向自鎖功能，可以有較大的減速比，輸入軸和輸出軸不在同一軸線上，也不在同一平面上。但是一般體積較大，傳動效率不高，精度不高。諧波減速機的諧波傳動是利用柔性元件可控的彈性變形來傳遞運動和動力的，體積不大、精度很高，但缺點是柔輪壽命有限、不耐沖擊，剛性與金屬件相比較差。輸入轉(zhuǎn)速不能太高。行星減速機其優(yōu)點是結(jié)構(gòu)比較緊湊，回程間隙小、精度較高，使用壽命很長，額定輸出扭矩可以做的很大。但價格略貴。齒輪減速機具有體積小，傳遞扭矩大的特點。齒輪減速機在模塊組合體系基礎(chǔ)上設(shè)計制造，有極多的電機組合、安裝形式和結(jié)構(gòu)方案，傳動比分級細(xì)密，滿足不同的使用工況，實現(xiàn)機電一體化。齒輪減速機傳動效率高，耗能低，性能優(yōu)越。擺線針輪減速機是一種采用擺線針齒嚙合行星傳動原理的傳動機型，是一種理想的傳動裝置，具有許多優(yōu)點，用途廣泛，并可正反運轉(zhuǎn)。
