? 如今,社會倡導節能環保,永磁變頻空壓機作為國民經濟中不可或缺的戰略性基礎機型,在我國空壓機市場占有舉足輕重的地位,滿足了企業節能環保的需求。
永(yong)磁(ci)(ci)(ci)(ci)(ci)變頻空壓機(ji)是(shi)一個(ge)新概念,其原(yuan)(yuan)理(li)依賴于(yu)永(yong)磁(ci)(ci)(ci)(ci)(ci)同(tong)(tong)步(bu)(bu)電(dian)(dian)機(ji)。稀土永(yong)磁(ci)(ci)(ci)(ci)(ci)變頻空壓機(ji)的(de)工作原(yuan)(yuan)理(li)與電(dian)(dian)勵(li)磁(ci)(ci)(ci)(ci)(ci)同(tong)(tong)步(bu)(bu)電(dian)(dian)機(ji)相同(tong)(tong),不同(tong)(tong)的(de)是(shi)前(qian)者用(yong)(yong)永(yong)磁(ci)(ci)(ci)(ci)(ci)體(ti)(ti)代替(ti)勵(li)磁(ci)(ci)(ci)(ci)(ci)繞組進(jin)行勵(li)磁(ci)(ci)(ci)(ci)(ci)。永(yong)磁(ci)(ci)(ci)(ci)(ci)電(dian)(dian)機(ji)的(de)三(san)相定子繞組中引入頻率為(wei)f的(de)三(san)相交(jiao)流電(dian)(dian)時,會以同(tong)(tong)步(bu)(bu)速度產生旋(xuan)(xuan)(xuan)轉(zhuan)(zhuan)(zhuan)磁(ci)(ci)(ci)(ci)(ci)場。穩態時,主極(ji)磁(ci)(ci)(ci)(ci)(ci)場與旋(xuan)(xuan)(xuan)轉(zhuan)(zhuan)(zhuan)磁(ci)(ci)(ci)(ci)(ci)場同(tong)(tong)步(bu)(bu)旋(xuan)(xuan)(xuan)轉(zhuan)(zhuan)(zhuan),所(suo)以轉(zhuan)(zhuan)(zhuan)子轉(zhuan)(zhuan)(zhuan)速也是(shi)同(tong)(tong)步(bu)(bu)轉(zhuan)(zhuan)(zhuan)速。定子旋(xuan)(xuan)(xuan)轉(zhuan)(zhuan)(zhuan)磁(ci)(ci)(ci)(ci)(ci)場和(he)永(yong)磁(ci)(ci)(ci)(ci)(ci)體(ti)(ti)建(jian)立的(de)主極(ji)磁(ci)(ci)(ci)(ci)(ci)場始(shi)終保持相對靜(jing)止,相互作用(yong)(yong),產生電(dian)(dian)磁(ci)(ci)(ci)(ci)(ci)轉(zhuan)(zhuan)(zhuan)矩,驅動電(dian)(dian)機(ji)旋(xuan)(xuan)(xuan)轉(zhuan)(zhuan)(zhuan),轉(zhuan)(zhuan)(zhuan)換能量。
東莞美博永磁(ci)變頻空壓機(ji)采用高效(xiao)稀土永磁(ci)同(tong)步電(dian)機(ji)(永磁(ci)電(dian)機(ji))。螺桿(gan)主(zhu)機(ji)和永磁(ci)電(dian)機(ji)共用一個主(zhu)軸,電(dian)機(ji)無(wu)軸承(cheng)。帶永磁(ci)體的轉(zhuan)子直接安裝在(zai)凸(tu)轉(zhuan)子的凸(tu)軸上,傳動效(xiao)率(lv)為(wei)100%。這種結構(gou)消(xiao)除了(le)傳統電(dian)機(ji)軸承(cheng)的故障(zhang)點,實現了(le)電(dian)機(ji)免(mian)維護。
稀土永磁(ci)(ci)(ci)材(cai)料具有優異的(de)(de)(de)磁(ci)(ci)(ci)性(xing)能(neng)(neng),經過磁(ci)(ci)(ci)化后(hou)無(wu)需額外(wai)的(de)(de)(de)能(neng)(neng)量(liang)就能(neng)(neng)建立起強大的(de)(de)(de)永久磁(ci)(ci)(ci)場。用稀土永磁(ci)(ci)(ci)電機(ji)代替傳統電機(ji)的(de)(de)(de)電勵(li)磁(ci)(ci)(ci)場,不僅效率高,而且結構簡單、運行可靠(kao)、體積小、重(zhong)量(liang)輕(qing)。既(ji)能(neng)(neng)達到(dao)傳統電勵(li)磁(ci)(ci)(ci)電機(ji)無(wu)法比擬的(de)(de)(de)高性(xing)能(neng)(neng)(如超高效率、超高速、超高響應速度),又能(neng)(neng)制造出滿(man)足特定運行要求的(de)(de)(de)特殊電機(ji),如電梯牽引電機(ji)、汽車專用電機(ji)等(deng)。稀土永磁(ci)(ci)(ci)電機(ji)與電力電子技(ji)術和(he)(he)微機(ji)控(kong)制技(ji)術的(de)(de)(de)結合,將(jiang)電機(ji)和(he)(he)傳動系統的(de)(de)(de)性(xing)能(neng)(neng)提高到(dao)了(le)一個新(xin)的(de)(de)(de)水(shui)平。從而提高配套技(ji)術裝備的(de)(de)(de)性(xing)能(neng)(neng)和(he)(he)水(shui)平,是(shi)汽車工業(ye)調整(zheng)產業(ye)結構的(de)(de)(de)重(zhong)要發展方向。
