防(fáng)爆(bào)電(diàn)機鐵芯的(de)好與(yǔ)壞，對整台防爆電機的質量起(qǐ)着至(zhì)關重(zhòng)要的(de)作用。鐵芯(xīn)質量差， 防爆電(diàn)機 的cos要(yào)降低；因(yīn)鐵損耗增加，效(xiào)率也要降低；因(yīn)空載(zǎi)電流(liú)大，負載電(diàn)流随(suí)之增(zēng)大，溫升也(yě)要升高；電(diàn)磁(cí)噪(zào)聲要(yào)增加；毛刺大、疊(dié)壓不齊，對(duì)絕緣(yuán)有(yǒu)直接(jiē)損傷，是(shì)繞組(zǔ)故障的禍(huò)根。爲了防止因(yīn)鐵芯質量差，絕(jué)緣易受損(sǔn)傷，制(zhì)造廠不得(dé)不采(cǎi)取消(xiāo)極的(de)措(cuò)施--增加主(zhǔ)絕緣厚(hòu)度，浪費材料，提(tí)高了防爆電機(jī)成本，散熱(rè)也差(chà)，而轉子鐵芯菱(líng)形還(hái)影響(xiǎng)動平(píng)衡的(de)精(jīng)度。這個是防爆電機鐵(tiě)芯故障的危害(hài)。 防爆電機 鐵芯的故障，嚴(yán)格的(de)講，指(zhǐ)的是鐵芯(xīn)制造(zào)質(zhì)量(liàng)。它由(yóu)毛刺大、疊壓不齊、裝壓(yā)不緊及(jí)變形四種(zhǒng)類型構成(chéng)(圖\文 xiaojikuaipao.top/ )。

explosion proof motor iron core of good and bad, the whole sets of explosion-proof motor quality plays a crucial role in. the core of poor quality, explosion-proof motor cos to reduce; because the iron losses increase, efficiency to decrease; because of the no-load current, load current increases, the temperature rise can be increased; electromagnetic noise will increase; burr, laminated not neat, the insulation has direct damage, is the bane of winding fault. in order to prevent poor quality for core, insulated vulnerable to injury, factory had to take measures to increase negative -- main insulation thickness, material waste, improves the explosion-proof motor cost, heat is poor, and the rotor core diamond also affects the dynamic balance precision. this is the explosion-proof motor iron core fault hazard. explosion proof motor iron core fault, strictly speaking, refers to the core manufacturing quality. it consists of burr, laminated not neat, loading is not pressed tightly and deformation of four types.
