同服電機(jī)，按照通常的區(qū)分劃分為步進(jìn)電機(jī)、直流有刷伺服電機(jī)、直流無刷同服電機(jī)、交流同服電機(jī)，隨著科技的日益進(jìn)步，很多特種同服電機(jī)應(yīng)運(yùn)而生，比如壓電陶瓷電機(jī)、直線電機(jī)以及音圈電機(jī)，在這里我 們主要講講通常意義下同服電機(jī)的選擇。選擇什么樣的伺服電機(jī)，在很大程度上取決于負(fù)載的物理特性，負(fù)載的工作特性、系統(tǒng)要求以及工作環(huán) 境。一旦系統(tǒng)要求確定后，無論選擇何種形式的伺服電機(jī)，首先要考慮的是選擇多大的電機(jī)合適，主要考慮 負(fù)載的物理特性，包括負(fù)載扭矩、慣量等。在伺服電機(jī)中，通常以扭矩或者力來衡量電機(jī)大小，所以選電機(jī),首先要計(jì)算出折算到電機(jī)軸端負(fù)載扭矩或者力的大小。計(jì)算出扭矩以后需求留出一部分余量，一般選擇電機(jī), 連續(xù)扭矩>=1.3倍負(fù)載扭矩，這樣能保證電機(jī)可靠的運(yùn)行。
