描述
是以接近于基波頻率所對(duì)應(yīng)的同步轉(zhuǎn)速旋轉(zhuǎn)的,因此,高次諧波電壓以較大的轉(zhuǎn)差切割轉(zhuǎn)子導(dǎo)條后,便會(huì)產(chǎn)生很大的轉(zhuǎn)子損耗。除此之外,還需考慮因集膚效應(yīng)所產(chǎn)生的附加銅耗。這些損耗都會(huì)使電動(dòng)機(jī)額外發(fā)熱,效率降低,輸出功率減小,如將普通三相異步電動(dòng)機(jī)運(yùn)行于變頻器輸出的非正弦條件下,其溫升一般要增加10%–20%。
電源是向電子設(shè)備提供功率的裝置,也稱(chēng)電源供應(yīng)器,它提供計(jì)算機(jī)中所有部件所需要的電能。
