減速機(jī)技術(shù)資料： 直流電機(jī)具有良好的啟動(dòng)特性和調(diào)速特性。因此,在調(diào)速性能要求較高的大型設(shè)備,比如軋鋼機(jī)上都采用直流電動(dòng)機(jī)拖動(dòng)。但它存在著直流換向問題,結(jié)構(gòu)復(fù)雜,維護(hù)檢修不方便,而且消耗有色金屬多。 一、直流電機(jī)的優(yōu)點(diǎn) 1.直流電機(jī)具有良好的啟動(dòng)特性和調(diào)速特性 2.直流電機(jī)的轉(zhuǎn)矩比較大 3.維修比較便宜。 4.直流電機(jī)的直流相對(duì)于交流比較節(jié)能環(huán)保。 二、直流電機(jī)的缺點(diǎn) 1.直流電機(jī)制造比較貴 2.有碳刷 三、交流電機(jī)的優(yōu)點(diǎn) 1.交流電機(jī) 制造比較便宜。 2.矢量變頻技術(shù)的發(fā)展，已經(jīng)可以用變頻電機(jī)模擬成直流電 3.相對(duì)于直流電機(jī)在結(jié)構(gòu)簡(jiǎn)單、維護(hù)容易、對(duì)環(huán)境要求低以及節(jié)能和提高生產(chǎn)力等方面具有足夠的優(yōu)勢(shì)，使得交流調(diào)速已經(jīng)廣泛運(yùn)用于工農(nóng)業(yè)生產(chǎn)、交通運(yùn)輸、國(guó)防以及日常生活之中。 四、交流電機(jī)的缺點(diǎn) 1.交流電機(jī)的啟動(dòng)性和調(diào)速性較差 交流電機(jī)根據(jù)轉(zhuǎn)速可分為同步電機(jī)和異步電機(jī)。 一、同步電機(jī) 同步電機(jī)的主要運(yùn)行方式有三種，即作為發(fā)電機(jī)、電動(dòng)機(jī)和補(bǔ)償機(jī)運(yùn)行。 作為發(fā)電機(jī)運(yùn)行是同步電機(jī)最主要的運(yùn)行方式，作為電動(dòng)機(jī)運(yùn)行是同步電機(jī)的另一種重要的運(yùn)行方式。同步電動(dòng)機(jī)的功率因數(shù)可以調(diào)節(jié)，在不要求調(diào)速的場(chǎng)合，應(yīng)用大型同步電動(dòng)機(jī)可以提高運(yùn)行效率。近年來(lái)，小型同步電動(dòng)機(jī)在變頻調(diào)速系統(tǒng)中開始得到較多地應(yīng)用。 同步電機(jī)還可以接于電網(wǎng)作為同步補(bǔ)償機(jī)。這時(shí)電機(jī)不帶任何機(jī)械負(fù)載，靠調(diào)節(jié)轉(zhuǎn)子中的勵(lì)磁電流向電網(wǎng)發(fā)出所需的感性或者容性無(wú)功功率，以達(dá)到改善電網(wǎng)功率因數(shù)或者調(diào)節(jié)電網(wǎng)電壓的目的。 二、異步電機(jī) 異步電機(jī)是一種交流電機(jī)，其負(fù)載時(shí)的轉(zhuǎn)速與所接電網(wǎng)的頻率之比不是恒定關(guān)系。還隨著負(fù)載的大小發(fā)生變化。負(fù)載轉(zhuǎn)矩越大，轉(zhuǎn)子的轉(zhuǎn)速越低。異步電機(jī)包括感應(yīng)電機(jī)、雙饋異步電機(jī)和交流換向器電機(jī)。感應(yīng)電機(jī)應(yīng)用最廣，在不致引起誤解或混淆的情況下，一般可稱感應(yīng)電機(jī)為異步電機(jī)。 優(yōu)點(diǎn)：結(jié)構(gòu)簡(jiǎn)單，制造方便，價(jià)格便宜，運(yùn)行方便。 缺點(diǎn)：功率因數(shù)滯后，輕載功率因數(shù)低，調(diào)速性能稍差。 主要做電動(dòng)機(jī)用，一般不做發(fā)電機(jī)！ 三相異步電機(jī)按轉(zhuǎn)子結(jié)構(gòu)形式分為屬籠式、繞線式；按外殼結(jié)構(gòu)形式可分為開啟式、防護(hù)式、封閉式和防爆式；按安裝形式可分為立式、臥式。 Square D KAP36225 225 A Circuit Breaker Square D 2510 MCW11 AC Manual Starter Size 1 SQUARE D 200 AMP 3 POLE CIRCUIT BREAKER TYPE KC KC34200 Q-38 SQUARE D 175AMP Electronic Trip Breaker LXL36175 U-101 SQUARE D 8903 LG80VO2 8 POLE LIGHTING CONTACTOR NIB WITH ENCLOSURE SQUARE D 8903 LG1000VO2 10 POLE LIGHTING CONTACTOR NIB WITH ENCLOSURE NEW SQUARE D STARTER 600VAC 18AMP NEMA + OPTIONS Square D TBX DES16S04 Series A1 SyMAX Module #11097 HGL26015 Square D Circuit Breaker HGF26015 Powerpact HGL26040 Square D Circuit Breaker HGF26040 Powerpact HGL26060 Square D Circuit Breaker HGF26060 Powerpact Square D 8536-SD01 8536-SDO1 8536SD01 Contactor Series A - New, No Box Square D 8903LO40V02 4 pole Lighting Contactor 8903 LO40 8903L040V02 SQUARE D QMB 3610 SAFLEX TWIN 100 600V SQUARE D 8736-SCO8-V02S USPP 8736SCO8V02S SQUARE D QMB-361TW NSPP QMB361TW Square D 9002 AW-117 9002AW117 Foot Switch Series C - New, No Box HGA260402 , Square D Molded Case Circuit Breaker 600V 40A New SQUARE D CONTACT KIT (9998LS10) NEW IN BOX SQUARE D 8536-SDG1-V02S USPP 8536SDG1V02S SQUARE D 9007-SGP1 NSPP 9007SGP1 SQUARE D HU364RB USPP HU364RB SQUARE D 8922-ETB-18/240 NSPP 8922ETB18240 SQUARE D Circuit Breaker KAL361501027 24VDC shunt KAL SQUARE D Circuit Breaker KAL361756139 KAL 3P 175A 600V SQD SQUARE D Circuit Breaker KHL3615017DC1684 KHL 150A SQD SQUARE D Circuit Breaker FCL340251027 24V shunt FCL Square D 8903 SP02 8903SP02 Lighting Contactor - Used Square D 9007 CO-5 (Pack of 6) 9007CO5 Snap Switch Series A SQUARE D EDB24015 FNFP EDB24015 NEW Square D SL SL400 400 amp 3 pole 600v Breaker SQUARE D PANELBOARD SWITCH 200 AMP 600V 3 POLE QMB364 Square D Power Interface Board 52011-390-01 54 Rev J New!!!
