過載能力不同
步進電機一般不具有過載能力。交流伺服電機具有較強的過載能力。以三洋交流伺服系統為例，它具有速度過載和轉矩過載能力。其最大轉矩為額定轉矩的二到三倍，可用于克服慣性負載在啟動瞬間的慣性力矩。步進電機因為沒有這種過載能力，在選型時為了克服這種慣性力矩，往往需要選取較大轉矩的電機，而機器在正常工作期間又不需要那么大的轉矩，便出現了力矩浪費的現象。

五、運行性能不同
步進電機的控制為開環控制，啟動頻率過高或負載過大易出現丟步或堵轉的現象，停止時轉速過高易出現過沖的現象，所以為保證其控制精度，應處理好升、降速問題。交流伺服驅動系統為閉環控制，驅動器可直接對電機編碼器反饋信號進行采樣，內部構成位置環和速度環，一般不會出現步進電機的丟步或過沖的現象，控制性能更為可靠。
六、速度響應性能不同
步進電機從靜止加速到工作轉速（一般為每分鐘幾百轉）需要200～400毫秒。交流伺服系統的加速性能較好，以山洋400W交流伺服電機為例，從靜止加速到其額定轉速3000RPM僅需幾毫秒，可用于要求快速啟停的控制場合。
綜上所述，交流伺服系統在許多性能方面都優于步進電機。但在一些要求不高的場合也經常用步進電機來做執行
電動機。所以，在控制系統的設計過程中要綜合考慮控制要求、成本等多方面的因素，選用適當的控制電機。
