感應(yīng)電機(jī)和永磁同步電機(jī)是兩種不同的交流電機(jī)，它們的區(qū)別如下：

　　工作原理不同：感應(yīng)電機(jī)是利用定子繞組中的交流電流在轉(zhuǎn)子中產(chǎn)生感應(yīng)電流，產(chǎn)生轉(zhuǎn)矩；而永磁同步電機(jī)則是利用永磁體和定子繞組產(chǎn)生的交流磁場，在轉(zhuǎn)子中產(chǎn)生電磁轉(zhuǎn)矩，從而實現(xiàn)運轉(zhuǎn)。

　　轉(zhuǎn)矩特性不同：感應(yīng)電機(jī)在啟動時能夠提供較大的轉(zhuǎn)矩，但在負(fù)載較大時轉(zhuǎn)速下降，轉(zhuǎn)矩下降，存在轉(zhuǎn)速滑差；而永磁同步電機(jī)的轉(zhuǎn)矩與轉(zhuǎn)速成正比，轉(zhuǎn)速變化較小，不存在滑差。

　　轉(zhuǎn)速控制方式不同：感應(yīng)電機(jī)的轉(zhuǎn)速一般通過變頻器來實現(xiàn)調(diào)速；而永磁同步電機(jī)的轉(zhuǎn)速可以通過改變電源頻率和極對數(shù)來實現(xiàn)調(diào)速。

　　運行穩(wěn)定性不同：感應(yīng)電機(jī)在負(fù)載突然變化時，可能出現(xiàn)轉(zhuǎn)速波動和失速現(xiàn)象；而永磁同步電機(jī)在負(fù)載變化時，轉(zhuǎn)速和轉(zhuǎn)矩的響應(yīng)速度更快，運行更加穩(wěn)定。

　　成本不同：感應(yīng)電機(jī)由于采用傳統(tǒng)的電磁感應(yīng)原理，不需要永磁體，因此相對成本較低；而永磁同步電機(jī)需要永磁體，成本較高。
