2、西門子電機發(fā)熱隨速度變化的情況
采用恒流驅(qū)動技術(shù)時,電機在靜態(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
電機發(fā)熱雖然一般不會影響電機的壽命,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,會影響電機的動態(tài)響應(yīng),高速會容易失步。
4、減少電機的發(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,對兩相電機,能用串聯(lián)的電機就不用并聯(lián)電機。細(xì)分驅(qū)動器由于電流波形接近正弦,諧波少,電機發(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電機只有自然風(fēng)冷,沒有外部冷卻系統(tǒng),熱量通過電機表面散發(fā)。1FK7 電機有很強的過載能力。
