三相異步電動機(jī)的調(diào)速方法三相異步電動機(jī)的調(diào)速方法包括：變極對數(shù)、定子調(diào)壓、定子變頻、串級調(diào)速、雙饋調(diào)速、液力耦合、電磁轉(zhuǎn)差離合器等，從調(diào)速時(shí)的能耗觀點(diǎn)來看，有高效調(diào)速方法與低效調(diào)速方法兩種：高效調(diào)速指時(shí)轉(zhuǎn)差率不變，因此無轉(zhuǎn)差損耗，如多速電動機(jī)、變頻調(diào)速以及能將轉(zhuǎn)差損耗回收的調(diào)速方法(如串級調(diào)速等)。有轉(zhuǎn)差損耗的調(diào)速方法屬低效調(diào)速，如轉(zhuǎn)子串電阻調(diào)速方法，能量就損耗在轉(zhuǎn)子回路中；電磁離合器的調(diào)速方法，能量損耗在離合器線圈中；液力耦合器調(diào)速，能量損耗在液力耦合器的油中。一般來說轉(zhuǎn)差損耗隨調(diào)速范圍擴(kuò)大而增加，如果調(diào)速范圍不大，能量損耗是很小的。從異步電動機(jī)的轉(zhuǎn)速公式可知，異步電動機(jī)要想改變轉(zhuǎn)速，必須從以下三個(gè)方面考慮：改變電動機(jī)定子繞組的磁極對數(shù)P，改變電動機(jī)的轉(zhuǎn)差率S，改變電動機(jī)供電源的頻率f，無憂二手電機(jī)回收參考價(jià)格，對應(yīng)于上述三個(gè)途徑的調(diào)速方法分別簡稱為：變極調(diào)速，變轉(zhuǎn)差率調(diào)速，無憂二手電機(jī)回收參考價(jià)格，變頻調(diào)速，無憂二手電機(jī)回收參考價(jià)格。1．變極調(diào)速（有級調(diào)速）由轉(zhuǎn)速公式可知，改變電動機(jī)定子繞組的磁極對數(shù)P，就可以改變其同步轉(zhuǎn)速，從而使運(yùn)行速度發(fā)生變化。達(dá)到調(diào)速的目的，但是異步電動機(jī)只有定子、轉(zhuǎn)子磁極對數(shù)相同時(shí)，定子、轉(zhuǎn)子磁勢才能相互作用產(chǎn)生磁轉(zhuǎn)矩。

直流電機(jī)修理為了充分發(fā)揮絕緣材料的特性，提高經(jīng)濟(jì)合理性，要按直流電機(jī)的不同絕緣部位所達(dá)到的比較高實(shí)際溫度，結(jié)合材料的機(jī)械、化學(xué)、物理性能綜合考慮，有區(qū)別地選用絕緣結(jié)構(gòu)中的各種組成材料，而不必苛求不分使用部位而一律選用所規(guī)定的同一絕緣等級的材料。為了將電機(jī)帶電部件與機(jī)座、鐵心等接地部件隔離開和將電位不同的各帶電部位隔開，電動機(jī)各部分使用了多種絕緣材料。電動機(jī)在運(yùn)行中發(fā)熱，使受到劇烈的溫度變化和長時(shí)期的熱作用，其絕緣性能逐步變壞直至完全喪失而擊穿。直流電機(jī)修理絕緣結(jié)構(gòu)的熱老化是使絕緣材料損壞的主要原因。為使電動機(jī)在規(guī)定壽命期限內(nèi)可靠運(yùn)行，必須針對各種不同形式、不同結(jié)構(gòu)、不同通風(fēng)方式的電動機(jī)選用不同的絕緣等級，從而規(guī)定出合適的發(fā)熱強(qiáng)度極限，以期達(dá)到安全使用壽命的目的。1.直流電機(jī)維修需要注意各連接線、引線要按原接線恢復(fù)正確，接觸面要平整、光潔、接觸良好。2.需要注意裝配要按分解時(shí)的反順序進(jìn)行。3.在裝配過程中需要注意不能碰傷磁極、電樞繞組及換向器、刷架、刷握等配件。4.直流電機(jī)維修需要注意各部件的安裝要按原記錄標(biāo)準(zhǔn)恢復(fù)，要保證相對位置正確無誤。5.需要注意安裝端蓋。</p><p>

鐵芯過熱多發(fā)生在夾件與鐵芯上。、電機(jī)繞組絕緣故障感應(yīng)電機(jī)的故障往往是由于繞組絕緣空洞或混有雜質(zhì)等缺陷造成的。絕緣缺陷主要是生產(chǎn)過程中造成的，因此電機(jī)的運(yùn)行狀況與使用壽命與生產(chǎn)工藝息息相關(guān)。絕緣缺陷和絕緣老化導(dǎo)致的絕緣故障都表現(xiàn)為電機(jī)內(nèi)活動性放電量增加，通過一些檢測實(shí)驗(yàn)可以獲得絕緣老化的一些數(shù)據(jù)參數(shù)，通過分析能夠判斷絕緣老化的程度和原因。、電機(jī)定子繞組匝間短路故障定子繞組匝間短路也是感應(yīng)電機(jī)常見故障之一，故障原因主要有生產(chǎn)工藝不合格和不正常的運(yùn)行兩個(gè)方面引起。、電機(jī)定子故障的發(fā)展過程感應(yīng)電機(jī)定子故障的**初階段，電機(jī)仍可正常運(yùn)行，功率、電壓及震動也都在正常范圍之內(nèi)，但此時(shí)電機(jī)定子磁場已發(fā)生改變，定子電流中可以檢測到故障特征。這里我們采用了定子電流法診斷感應(yīng)電機(jī)定子故障，隨著故障的惡化，電機(jī)正常運(yùn)行受到影響，震動加劇，輸出轉(zhuǎn)矩波動，電機(jī)工況異常，故障即將爆發(fā)。再進(jìn)一步發(fā)展，更多的絕緣被損壞使得短路故障加劇，劇烈震動，定子溫升劇增使得電機(jī)無法正常運(yùn)行。、電機(jī)定子故障后果（1）定子匝間短路引起電機(jī)機(jī)身和機(jī)座振動。感應(yīng)電機(jī)一旦發(fā)生故障，電機(jī)機(jī)身和各零部件都會出現(xiàn)振動。
