MPL-A430P-MJ74AA

一、改變極對(duì)數(shù)調(diào)速：優(yōu)點(diǎn)：①無(wú)附加轉(zhuǎn)差損耗，效率高;②控制電路簡(jiǎn)單，易維修，價(jià)格低;③與定子調(diào)壓或電磁轉(zhuǎn)差離合器配合可得到效率較高的平滑調(diào)速。缺點(diǎn)：有級(jí)調(diào)速，不能實(shí)現(xiàn)無(wú)級(jí)平滑的調(diào)速，并且由于受到電機(jī)結(jié)構(gòu)和制造工藝的限制，通常只能實(shí)現(xiàn)2～3種極對(duì)數(shù)的有級(jí)調(diào)速，調(diào)速范圍相當(dāng)有限。

二、變頻調(diào)速：優(yōu)點(diǎn)：①無(wú)附加轉(zhuǎn)差損耗，效率高，調(diào)速范圍寬;②對(duì)于低負(fù)載運(yùn)行時(shí)間較長(zhǎng)，或起、停較頻繁的場(chǎng)合，可以達(dá)到節(jié)電和保護(hù)電機(jī)的目的。缺點(diǎn)：技術(shù)較復(fù)雜，價(jià)格較高。

三、換向器電機(jī)調(diào)速：優(yōu)點(diǎn)：①具有交流同步電機(jī)結(jié)構(gòu)簡(jiǎn)單和直流電機(jī)良好的調(diào)速性能;②低速時(shí)用電源電壓、高速時(shí)用步進(jìn)電機(jī)反電勢(shì)自然換流，運(yùn)行可靠;③無(wú)附加轉(zhuǎn)差損耗，效率高，適用于高速大容量同步電機(jī)的啟動(dòng)和調(diào)速。缺點(diǎn)：過(guò)載能力較低，原有電機(jī)的容量不能充分發(fā)揮。

四、串級(jí)調(diào)速：優(yōu)點(diǎn)：①可以將調(diào)速過(guò)程中產(chǎn)生的轉(zhuǎn)差能量加以回饋利用。效率高;②裝置容量與調(diào)速范圍成正比，適用于70%～95%的調(diào)速。缺點(diǎn)：功率因素較低，有諧波干擾，正常運(yùn)行時(shí)無(wú)制動(dòng)轉(zhuǎn)矩，適用于單象限運(yùn)行的負(fù)載。

五、定子調(diào)壓調(diào)速：優(yōu)點(diǎn)：①線路簡(jiǎn)單，裝置體積小，價(jià)格便宜;②使用、維修方便。缺點(diǎn)：①調(diào)速過(guò)程中增加轉(zhuǎn)差損耗，此損耗使轉(zhuǎn)子發(fā)熱，效率較低;②調(diào)速范圍比較小;③要求采用高轉(zhuǎn)差電機(jī)，比如特殊設(shè)計(jì)的力矩電機(jī)，所以特性較軟，一般適用于55kW以下的異步電機(jī)。

六、電磁轉(zhuǎn)差離合器調(diào)速：優(yōu)點(diǎn)：①結(jié)構(gòu)簡(jiǎn)單，控制裝置容量小，價(jià)值便宜;②運(yùn)行可靠，維修容易;③無(wú)諧波干擾。缺點(diǎn)：①速度損失大，因?yàn)殡姶呸D(zhuǎn)差離合器本身轉(zhuǎn)差較大，所以輸出軸的高轉(zhuǎn)速僅為電機(jī)同步轉(zhuǎn)速的80%～90%;②調(diào)速過(guò)程中轉(zhuǎn)差功率全部轉(zhuǎn)化成熱能形式的損耗，效率低。

七、轉(zhuǎn)子串電阻調(diào)速：優(yōu)點(diǎn)：①技術(shù)要求較低，易于掌握;②設(shè)備費(fèi)用低;③無(wú)電磁諧波干擾。缺點(diǎn)：①串鑄鐵電阻只能進(jìn)行有級(jí)調(diào)速。若用液體電阻進(jìn)行無(wú)級(jí)調(diào)速，則維護(hù)、保養(yǎng)要求較高;②調(diào)速過(guò)程中附加的轉(zhuǎn)差功率全部轉(zhuǎn)化為所串電阻發(fā)熱形式的損耗，效率低。③調(diào)速范圍不大。
