描述
永磁同步電動(dòng)機(jī)屬于異步啟動(dòng)永磁同步電動(dòng)機(jī),其磁場系統(tǒng)由一個(gè)或多個(gè)永磁體組成,通常是在用鑄鋁或銅條焊接而成的籠型轉(zhuǎn)子的內(nèi)部,按所需的極數(shù)裝鑲有永磁體的磁極。定子結(jié)構(gòu)與異步電動(dòng)機(jī)類似。
當(dāng)定子繞組接通電源后,電動(dòng)機(jī)以異步電動(dòng)機(jī)原理起動(dòng)動(dòng)轉(zhuǎn),加速運(yùn)轉(zhuǎn)至同步轉(zhuǎn)速時(shí),由轉(zhuǎn)子永磁磁場和定子磁場產(chǎn)生的同步電磁轉(zhuǎn)矩(由轉(zhuǎn)子永磁磁場產(chǎn)生的電磁轉(zhuǎn)矩與定子磁場產(chǎn)生的磁阻轉(zhuǎn)矩合成)將轉(zhuǎn)子牽入同步,電動(dòng)機(jī)進(jìn)入同步運(yùn)行。
磁阻同步電動(dòng)機(jī)磁阻同步電動(dòng)機(jī)也稱反應(yīng)式同步電動(dòng)機(jī),是利用轉(zhuǎn)子交軸和直軸磁阻不等而產(chǎn)生磁阻轉(zhuǎn)矩的同步電動(dòng)機(jī),其定子與異步電動(dòng)機(jī)的定子結(jié)構(gòu)類似,只是轉(zhuǎn)子結(jié)構(gòu)不同。
