2711-B6C3磁阻電機(jī)的缺點(diǎn)：

　　1. 磁阻電機(jī)難以同步運(yùn)行。由于轉(zhuǎn)子受磁場作用的位置很難保持與磁場方向同步，因此，這種電機(jī)的性能在高速運(yùn)行時(shí)發(fā)生變化。

　　2. 控制成本高：磁阻電機(jī)需要復(fù)雜的控制器才能實(shí)現(xiàn)的速度和位置控制，因此，控制成本和安裝電機(jī)的技術(shù)難度都比較高。

　　3. 須開發(fā)成本高：由于磁阻電機(jī)的特有優(yōu)點(diǎn)，研究和開發(fā)這種電機(jī)所需的成本較高，因此生產(chǎn)成本可能會(huì)比較高。

　　4. 發(fā)熱問題：磁阻電機(jī)在運(yùn)行過程中會(huì)出現(xiàn)很高的整體輸電損耗，這意味著電機(jī)會(huì)產(chǎn)生高溫，需要額外的散熱系統(tǒng)或控制方法來保持溫度穩(wěn)定。

　　綜上所述，雖然磁阻電機(jī)在許多方面都具有各種優(yōu)點(diǎn)，但其控制成本較高，且受頻率變化的限制，因此在特定應(yīng)用中，使用磁阻電機(jī)可能不是佳選擇。
