style="text-indent:25px">變頻調(diào)速的優(yōu)點是調(diào)速功率高，歸于高效調(diào)速方法。這是因為在頻率改變后，電動機仍在同步轉(zhuǎn)速鄰近運轉(zhuǎn)，基本堅持額外轉(zhuǎn)差。只是在變頻設(shè)備體系中會發(fā)生變流損失，以及因為高次諧波的影響，電動機的損耗增加，然后功率有所下降。調(diào)速規(guī)模寬，一般可達20:1，并在整個調(diào)速規(guī)模內(nèi)具有高的調(diào)速功率。所以變頻調(diào)速適用于調(diào)速規(guī)模寬，且常常處于低負荷狀態(tài)下運轉(zhuǎn)的場合。機械特性較硬，在無自動控制時，轉(zhuǎn)速改變率在5%以下；當選用自動控制時，能做高精度運轉(zhuǎn)，把轉(zhuǎn)速波動率控制在0.5%|~1%左右。電子開關(guān)器件代替?zhèn)鹘y(tǒng)的接觸式換向器和電刷。</p><div
