AB 1756模塊 1756-RM2參數(shù)規(guī)格:
交流伺服電動(dòng)機(jī)的工作原理與分相式單相異步電動(dòng)機(jī)雖然相似,但前者的轉(zhuǎn)子電阻比后者大得多,所以伺服電動(dòng)機(jī)與單機(jī)異步電動(dòng)機(jī)相比,有三個(gè)顯著特點(diǎn):
A、起動(dòng)轉(zhuǎn)矩大
由于轉(zhuǎn)子電阻大,其轉(zhuǎn)矩特性曲線與普通異步電動(dòng)機(jī)的轉(zhuǎn)矩特性曲線相比,有明顯的區(qū)別。它可使臨界轉(zhuǎn)差率S0>1,這樣不僅使轉(zhuǎn)矩特性(機(jī)械特性)更接近于線性,而且具有較大的起動(dòng)轉(zhuǎn)矩。因此,當(dāng)定子一有控制電壓,轉(zhuǎn)子立即轉(zhuǎn)動(dòng),即具有起動(dòng)快、靈敏度高的特點(diǎn)。
B、運(yùn)行范圍較廣
C、無自轉(zhuǎn)現(xiàn)象
正常運(yùn)轉(zhuǎn)的伺服電動(dòng)機(jī),只要失去控制電壓,電機(jī)立即停止運(yùn)轉(zhuǎn)。當(dāng)伺服電動(dòng)機(jī)失去控制電壓后,它處于單相運(yùn)行狀態(tài),由于轉(zhuǎn)子電阻大,定子中兩個(gè)相反方向旋轉(zhuǎn)的旋轉(zhuǎn)磁場(chǎng)與轉(zhuǎn)子作用所產(chǎn)生的兩個(gè)轉(zhuǎn)矩特性(T1-S1、T2-S2曲線)以及合成轉(zhuǎn)矩特性(T-S曲線)
