優點

由于稀土(tu)永(yong)磁(ci)(ci)材料的(de)磁(ci)(ci)性能(neng)優異，它(ta)經過充磁(ci)(ci)后(hou)不再(zai)需要外(wai)加能(neng)量就能(neng)建立很強(qiang)的(de)*磁(ci)(ci)場，用來替(ti)代傳(chuan)統電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)的(de)電(dian)(dian)(dian)(dian)勵磁(ci)(ci)場所制(zhi)(zhi)成的(de)稀土(tu)永(yong)磁(ci)(ci)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)不僅效率高，而且結(jie)構簡單、運(yun)行可靠(kao)，還可做(zuo)到體積小(xiao)、重(zhong)(zhong)量輕。既可達到傳(chuan)統電(dian)(dian)(dian)(dian)勵磁(ci)(ci)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)所*的(de)高性能(neng)（如(ru)特高效、特高速、特高響應(ying)速度），又可以制(zhi)(zhi)成能(neng)滿足特定(ding)運(yun)行要求的(de)特種電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)，如(ru)電(dian)(dian)(dian)(dian)梯曳引電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)、汽車電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)等。稀土(tu)永(yong)磁(ci)(ci)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)與電(dian)(dian)(dian)(dian)力電(dian)(dian)(dian)(dian)子技(ji)術和微機(ji)(ji)(ji)控(kong)制(zhi)(zhi)技(ji)術相結(jie)合，更(geng)使(shi)電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)及傳(chuan)動系(xi)統的(de)性能(neng)提高到一個嶄新的(de)水平(ping)。從(cong)而提高所配套的(de)技(ji)術裝備的(de)性能(neng)和水平(ping)，是電(dian)(dian)(dian)(dian)機(ji)(ji)(ji)行業調整產業結(jie)構的(de)重(zhong)(zhong)要發展方向。

稀土永(yong)(yong)磁電(dian)(dian)機(ji)的(de)(de)應用(yong)范(fan)圍(wei)極為廣泛，幾乎遍及(ji)航天、國防、裝備制(zhi)造、工(gong)農業生(sheng)產(chan)和日(ri)常生(sheng)活的(de)(de)各個領域。它包括永(yong)(yong)磁同(tong)步電(dian)(dian)動機(ji)、永(yong)(yong)磁發電(dian)(dian)機(ji)、直(zhi)流電(dian)(dian)動機(ji)、無刷直(zhi)流電(dian)(dian)動機(ji)、交流永(yong)(yong)磁伺服電(dian)(dian)動機(ji)、永(yong)(yong)磁直(zhi)線電(dian)(dian)機(ji)、特種永(yong)(yong)磁電(dian)(dian)機(ji)及(ji)相關的(de)(de)控制(zhi)系統，幾乎覆蓋了整個電(dian)(dian)機(ji)行業。

應(ying)用

交(jiao)流(liu)永磁同步(bu)電動(dong)機(ji)由于其(qi)體積小(xiao)、重量輕(qing)、高效節能等一系(xi)列優點(dian)，越來越引(yin)起人(ren)們(men)重視，其(qi)控制(zhi)技術日趨(qu)成熟，控制(zhi)器(qi)已產品化。中小(xiao)功率的(de)異(yi)步(bu)電動(dong)機(ji)變頻調(diao)速正(zheng)逐步(bu)為永磁同步(bu)電動(dong)機(ji)調(diao)速系(xi)統所取(qu)代。電梯驅動(dong)就是一個典型的(de)例子。電梯的(de)驅動(dong)系(xi)統對電機(ji)的(de)加速、穩(wen)速、制(zhi)動(dong)、定位都有一定的(de)要(yao)求(qiu)。早期人(ren)們(men)采用直流(liu)電動(dong)機(ji)調(diao)速系(xi)統，其(qi)缺點(dian)是不言而喻的(de)。

70年代變(bian)頻技術發(fa)展(zhan)成熟(shu)，異(yi)步(bu)電(dian)(dian)動(dong)(dong)機的(de)(de)變(bian)頻調(diao)(diao)速(su)驅(qu)動(dong)(dong)迅速(su)取代了(le)電(dian)(dian)梯(ti)行業中的(de)(de)直流調(diao)(diao)速(su)系(xi)統。而這幾年電(dian)(dian)梯(ti)行業中最新驅(qu)動(dong)(dong)技術就是永磁(ci)同步(bu)電(dian)(dian)動(dong)(dong)機調(diao)(diao)速(su)系(xi)統，其(qi)體(ti)積小、節能、控(kong)制性能好、又容(rong)易做成低速(su)直接驅(qu)動(dong)(dong)，消(xiao)除齒輪減(jian)速(su)裝置；其(qi)低噪聲(sheng)、平層精度和舒(shu)適(shi)性都優于以(yi)(yi)前的(de)(de)驅(qu)動(dong)(dong)系(xi)統，適(shi)合在無機房電(dian)(dian)梯(ti)中使(shi)用(yong)。永磁(ci)同步(bu)電(dian)(dian)動(dong)(dong)機驅(qu)動(dong)(dong)系(xi)統很快得到各(ge)大電(dian)(dian)梯(ti)公司青睞，與其(qi)配(pei)套的(de)(de)專用(yong)變(bian)頻器系(xi)列產品(pin)已有(you)多種牌號上市。可(ke)以(yi)(yi)預(yu)見，在調(diao)(diao)速(su)驅(qu)動(dong)(dong)的(de)(de)場合，將會是永磁(ci)同步(bu)電(dian)(dian)動(dong)(dong)機的(de)(de)天(tian)下。
