2、西門子電機(jī)發(fā)熱隨速度變化的情況

采用恒流驅(qū)動技術(shù)時，電機(jī)在靜態(tài)和低速下，電流會維持相對恒定，以保持恒力矩輸出。速度高到一定程度，電機(jī)內(nèi)部反電勢升高，電流將逐步下降，力矩也會下降。

　　3、發(fā)熱帶來的影響

　　電機(jī)發(fā)熱雖然一般不會影響電機(jī)的壽命，對大多數(shù)客戶來說沒必要理會。嚴(yán)重的發(fā)熱會帶來一些負(fù)面影響。如電機(jī)內(nèi)部各部分熱膨脹系數(shù)不同導(dǎo)致結(jié)構(gòu)應(yīng)力的變化和內(nèi)部氣隙的微小變化，會影響電機(jī)的動態(tài)響應(yīng)，高速會容易失步。

　　4、減少電機(jī)的發(fā)熱

　　減少發(fā)熱，就是減少銅損和鐵損。 減少銅損有兩個方向，減少電阻和電流，這就要求在選型時盡量選擇電阻小和額定電流小的電機(jī)，對兩相電機(jī)，能用串聯(lián)的電機(jī)就不用并聯(lián)電機(jī)。細(xì)分驅(qū)動器由于電流波形接近正弦，諧波少，電機(jī)發(fā)熱也會較少。 減少鐵損的辦法不多，電壓等級與之有關(guān)，高壓驅(qū)動的電機(jī)雖然會帶來高速特性的提升，但也帶來發(fā)熱的增加。

1FK7電機(jī)只有自然風(fēng)冷，沒有外部冷卻系統(tǒng)，熱量通過電機(jī)表面散發(fā)。1FK7 電機(jī)有很強的過載能力。
