有些系統(tǒng)如傳送裝置，升降裝置等要求伺服電機能盡快停車，而在故障、急停、電源斷電時伺服器沒有再生制動，無法對電機減速。同時系統(tǒng)的機械慣量又較大，這時對動態(tài)制動器的要依據(jù)負載的輕重、電機的工作速度等進行選擇。

有些系統(tǒng)要維持機械裝置的靜止位置，需要電機提供較大的輸出轉(zhuǎn)矩，且停止的時間較長。如果使用伺服的自鎖功能，往往會造成電機過熱或放大器過載，這種情況就要選擇帶電磁制動的電機。

有的伺服驅(qū)動器有內(nèi)置的再生制動單元，但當再生制動較頻繁時，可能引起直流母線電壓過高，這時需另配再生制動電阻。再生制動電阻是否需要另配，配多大，可參照相應(yīng)樣本的使用說明來配。

如果選擇了帶電磁制動器的伺服電機，電機的轉(zhuǎn)動慣量會增大，計算轉(zhuǎn)矩時要進行考慮

工業(yè)機器人使用頻率非常高，經(jīng)常會二十四小時工作，因此對機器人零件的質(zhì)量要求非常高，伺服電機是工業(yè)機器人的核心裝置，伺服電機選型就變得尤為重要，為了選擇的伺服電機，大家也可以從價格，重量，體積等多個指標來選擇。
