額定轉矩（Rated torque）：指電機在額定電壓、額定電流、額定速度下所能輸出的大轉矩。

額定轉速（Rated speed）：指電機在額定電壓、額定電流下所能輸出的轉速。

峰值轉矩（Peak torque）：指電機在瞬間能夠輸出的大轉矩，通常用于電機的加速和減速過程中。

峰值電流（Peak current）：指電機在瞬間能夠承受的大電流，通常與峰值轉矩相對應。

大加速度（Maximum acceleration）：指電機在單位時間內的加速度大值，通常用于電機加速和減速的控制。

零負載轉速（No-load speed）：指電機在無負載情況下的轉速，通常比額定轉速高。

編碼器分辨率（Encoder resolution）：指電機的反饋裝置（如編碼器）每轉產生的脈沖數，通常用于閉環控制中檢測電機的位置和速度。

功率（Power）：指電機輸出的功率，通常以瓦特（W）或馬力（HP）表示。

我們在選擇伺服電機的時候，都應該關注哪些參數呢？

1、首先，是轉速，即一分鐘電機多能夠轉多少圈，單位一般為rpm。目前，常見的伺服電機轉速有1000rpm、1500rpm、2000rpm、3000rpm等等。也不是說轉速越高就越好，我們需要綜合的看，一般轉速越高扭矩就越小。

2、然后就是扭矩，承接上面的內容，伺服電機轉速越高扭矩就相對來說越小，但這是相對于這臺電機自己來說的，比如750W的電機在3000rpm時的扭矩可能仍高于200W電機2500rpm的扭矩。常見的扭矩數值有0.64NM、1.27NM、2.38NM等等。

3、再然后是伺服電機功率，即電機是多少瓦特的。中小型伺服電機的功率可能只有200W或者是400W這樣子，而大功率伺服電機有可能超過1000W。在選擇時也要看設備的綜合參數和自己的時機需求，按照具有性價比的方式買。

4、還有就是伺服電機的基座大小、編碼器的類型、轉軸的直徑等等，這都需要和你的項目做好對比。比如說，你本來需要17位多圈值的編碼器就夠了，你非要弄一個23位的，這不錢燒的嗎？何必呢？
