變(bian)頻器維修技(ji)術中電(dian)機(ji)(ji)的(de)(de)損(sun)(sun)傷首要有(you)以下(xia)幾個方面：①電(dian)機(ji)(ji)發(fa)熱嚴(yan)(yan)峻、噪聲添加(jia)，招(zhao)致(zhi)電(dian)機(ji)(ji)的(de)(de)壽數(shu)縮短;②電(dian)機(ji)(ji)的(de)(de)定(ding)(ding)子繞組(zu)絕(jue)緣損(sun)(sun)壞(huai)，這種表(biao)(biao)象的(de)(de)發(fa)生時間不定(ding)(ding)，短則數(shu)周，長(chang)則數(shu)月;③電(dian)機(ji)(ji)的(de)(de)軸承損(sun)(sun)壞(huai)，這種表(biao)(biao)象的(de)(de)發(fa)生時間不定(ding)(ding)，短則數(shu)周，長(chang)則數(shu)月;導致(zhi)這些毛病(bing)現象的(de)(de)底子原因(yin)是(shi)(shi)變(bian)頻器輸出(chu)的(de)(de)PWM脈(mo)沖電(dian)壓波(bo)形(xing)。脈(mo)沖電(dian)壓的(de)(de)上升沿越陡(dou)，頻率越高，對電(dian)機(ji)(ji)的(de)(de)損(sun)(sun)傷越嚴(yan)(yan)峻。現代變(bian)頻器尋求(qiu)體積更小，功率更高。到達這個意(yi)圖(tu)的(de)(de)辦法就是(shi)(shi)添加(jia)PWM電(dian)壓波(bo)形(xing)的(de)(de)陡(dou)度。但(dan)是(shi)(shi)，這招(zhao)致(zhi)上述的(de)(de)一(yi)些問(wen)題也越來(lai)越嚴(yan)(yan)峻。直流機(ji)(ji)電(dian)電(dian)機(ji)(ji)響應快速，要較大起動轉(zhuan)矩(ju)，可提供額(e)定(ding)(ding)轉(zhuan)矩(ju)的(de)(de)性能。
