大家都知道，轉子作為電機中重要的組成部件，轉子質量對電機的性能影響較大，下面山東盛華變頻電機廠家，較詳細地討論這些缺陷產生的原因及其對電機性能的影響。

（1）旋轉葉(xie)鐵(tie)心稱(cheng)重(zhong)不高旋轉葉(xie)鐵(tie)心稱(cheng)重(zhong)不高的(de)原因有：

①馬達轉子沖片鋸齒狀過大；

②硅鋼片鋼板厚度不穩；

③葉輪沖片有銹或不乾凈；

④壓裝(zhuang)時壓小（滑片鐵心的壓裝(zhuang)壓應該為2.5~.MPa）。

⑤鑄鋁馬達(da)(da)旋(xuan)(xuan)(xuan)轉(zhuan)葉鐵心加溫(wen)(wen)環境溫(wen)(wen)度過高，時(shi)間(jian)段過高，鐵心燒損加重，使(shi)鐵心凈(jing)(jing)長擴(kuo)(kuo)大。馬達(da)(da)旋(xuan)(xuan)(xuan)轉(zhuan)葉鐵心凈(jing)(jing)重不(bu)足夠，等同于于馬達(da)(da)旋(xuan)(xuan)(xuan)轉(zhuan)葉鐵心凈(jing)(jing)長極大減少，使(shi)馬達(da)(da)旋(xuan)(xuan)(xuan)轉(zhuan)葉齒、馬達(da)(da)旋(xuan)(xuan)(xuan)轉(zhuan)葉扼部剖占地面擴(kuo)(kuo)大，則磁通(tong)體積增(zeng)強(qiang)。對(dui)高壓(ya)馬達(da)(da)耐熱性的不(bu)良(liang)影響(xiang)是：勵磁電(dian)交流(liu)電(dian)增(zeng)強(qiang)，馬達(da)(da)功率質數影響(xiang)，高壓(ya)馬達(da)(da)定子交流(liu)電(dian)增(zeng)強(qiang)，馬達(da)(da)旋(xuan)(xuan)(xuan)轉(zhuan)葉銅損增(zeng)強(qiang)，效果影響(xiang)，溫(wen)(wen)度升(sheng)降的升(sheng)高。

（2）葉片(pian)錯片(pian)、槽斜線打不直(zhi) 出(chu)現葉片(pian)錯片(pian)的原故有：

①電機(ji)定轉子(zi)鐵心壓裝時沒用(yong)得著槽樣棒位置，槽壁不美觀。

②假軸上的斜鍵和沖片上鍵槽間的協調厚(hou)度(du)過大；

③壓(ya)裝時的壓(ya)力差小，提(ti)前預熱后沖片鋸(ju)齒狀及污漬(zi)被(bei)燒去，使定子和轉子片脫落；

④旋(xuan)轉葉加(jia)熱后在地板上亂扔亂滾，旋(xuan)轉葉沖片存在角位(wei)移(yi)。

之(zhi)內(nei)異常現象(xiang)將使(shi)同(tong)(tong)步(bu)(bu)(bu)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)同(tong)(tong)步(bu)(bu)(bu)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)定(ding)(ding)滑片槽口擴大，同(tong)(tong)步(bu)(bu)(bu)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)同(tong)(tong)步(bu)(bu)(bu)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)定(ding)(ding)滑片槽漏抗(kang)增(zeng)(zeng)(zeng)多(duo)(duo)，導(dao)條受力擴大，導(dao)條內(nei)阻(zu)增(zeng)(zeng)(zeng)多(duo)(duo)，并對同(tong)(tong)步(bu)(bu)(bu)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)特性帶來(lai)如下所示導(dao)致：最(zui)多(duo)(duo)慣量(liang)減少，開(kai)機(ji)(ji)(ji)(ji)慣量(liang)減少，滿負荷時的電(dian)(dian)(dian)抗(kang)工作直流(liu)電(dian)(dian)(dian)增(zeng)(zeng)(zeng)多(duo)(duo)，率條件(jian)減少；定(ding)(ding)子、同(tong)(tong)步(bu)(bu)(bu)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)同(tong)(tong)步(bu)(bu)(bu)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)定(ding)(ding)滑片工作直流(liu)電(dian)(dian)(dian)增(zeng)(zeng)(zeng)多(duo)(duo)，定(ding)(ding)子銅耗增(zeng)(zeng)(zeng)多(duo)(duo)；同(tong)(tong)步(bu)(bu)(bu)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)同(tong)(tong)步(bu)(bu)(bu)電(dian)(dian)(dian)機(ji)(ji)(ji)(ji)定(ding)(ding)滑片耗損率增(zeng)(zeng)(zeng)多(duo)(duo)，率減少，表(biao)面(mian)溫度高，轉(zhuan)差(cha)率大。

（3）定(ding)子和轉子斜(xie)槽厚長(chang)于或(huo)不(bu)低于不(bu)得(de)值(zhi)

斜槽寬敞于或值(zhi)(zhi)為充許(xu)值(zhi)(zhi)的(de)的(de)原因(yin)，其主要是葉片鐵心壓裝(zhuang)時并沒有選(xuan)用假軸上(shang)的(de)斜鍵分析，或假軸制作時斜鍵的(de)斜度外形尺寸超(chao)差。

對電機的的性能(neng)的引響：

①斜槽(cao)肥大于限(xian)制值，旋(xuan)轉葉(xie)斜槽(cao)漏(lou)(lou)抗擴(kuo)增，伺服交流(liu)接觸器總漏(lou)(lou)抗擴(kuo)增；導條時長(chang)添加(jia)，導條功率電阻擴(kuo)增，對伺服交流(liu)接觸器效果危(wei)害同項（2）。

②斜槽(cao)寬小(xiao)(xiao)于等于不(bu)可以(yi)值(zhi)時，定子和(he)轉(zhuan)子斜槽(cao)漏(lou)抗(kang)降(jiang)低(di)了(le)大(da)約，電(dian)動(dong)機總漏(lou)抗(kang)降(jiang)低(di)了(le)大(da)約，打(da)火交流電(dian)大(da)小(xiao)(xiao)增強(qiang)（是由于打(da)火交流電(dian)大(da)小(xiao)(xiao)與漏(lou)抗(kang)關系不(bu)大(da)）。最后(hou)，電(dian)動(dong)機的背(bei)景噪聲和(he)運動(dong)大(da)。
