  電動(dòng)機(jī)的選擇主要有電動(dòng)機(jī)的類型、結(jié)構(gòu)型式、容量、額定電壓與額定轉(zhuǎn)速。
        電動(dòng)機(jī)選擇的基本原則是：
（1）根據(jù)生產(chǎn)機(jī)械調(diào)速的要求選擇電動(dòng)機(jī)的種類。
（2）工作過程中電動(dòng)機(jī)容量要得到充分利用。
（3）根據(jù)工作環(huán)境選擇電動(dòng)機(jī)的結(jié)構(gòu)型式。
       應(yīng)該強(qiáng)調(diào)，在滿足設(shè)計(jì)要求情況下優(yōu)先考慮采用結(jié)構(gòu)簡單，價(jià)格便宜，使用維護(hù)方便的三相交流異步電動(dòng)機(jī)。
        正確選擇電動(dòng)機(jī)容量是電動(dòng)機(jī)選擇中的關(guān)鍵問題。電動(dòng)機(jī)容量計(jì)算有兩種方法，一種是分析計(jì)算法，另一種是統(tǒng)計(jì)類比法。分析計(jì)算法是按照機(jī)械功率估計(jì)電動(dòng)機(jī)的工作情況，預(yù)選一臺(tái)電動(dòng)機(jī)，然后按照電動(dòng)機(jī)實(shí)際負(fù)載情況做出負(fù)載圖，根據(jù)負(fù)載圖校驗(yàn)溫升情況，確定預(yù)選電動(dòng)機(jī)是否合適，不合適時(shí)再重新選擇，直到電動(dòng)機(jī)合適為止。
        電動(dòng)機(jī)容量的分析計(jì)算在有關(guān)論著中有詳細(xì)介紹，這里不再重復(fù)
