說起直線(xian)電機(ji)(ji)，是否(fou)知(zhi)道永磁同步平面電機(ji)(ji)有什么關系(xi)，又(you)有那些區別等，它們(men)的(de)工(gong)作原理是否(fou)一樣，平面電機(ji)(ji)與直線(xian)電機(ji)(ji)結(jie)構的(de)演變發展。

　　平(ping)(ping)面(mian)(mian)電(dian)(dian)(dian)機(ji)是一種能將電(dian)(dian)(dian)磁(ci)能量直接轉化(hua)為平(ping)(ping)面(mian)(mian)運動(dong)的(de)(de)(de)電(dian)(dian)(dian)機(ji)。它通常由定子、轉子和支承(cheng)部件等組成。在支承(cheng)部件和電(dian)(dian)(dian)磁(ci)力作用(yong)的(de)(de)(de)約束下(xia)，平(ping)(ping)面(mian)(mian)電(dian)(dian)(dian)機(ji)的(de)(de)(de)執行機(ji)構可以驅動(dong)負載產生二維平(ping)(ping)面(mian)(mian)運動(dong)。平(ping)(ping)面(mian)(mian)電(dian)(dian)(dian)動(dong)機(ji)直接使用(yong)電(dian)(dian)(dian)磁(ci)能量從(cong)平(ping)(ping)面(mian)(mian)運動(dong)與(yu)(yu)高(gao)功(gong)率密度(du)、熱耗低(di)、精度(du)高(gao)的(de)(de)(de)特點(dian)，因此可以節省(sheng)從(cong)旋轉平(ping)(ping)面(mian)(mian)運動(dong)線性運動(dong)的(de)(de)(de)中間轉換(huan)裝置，可以控制對象與(yu)(yu)電(dian)(dian)(dian)機(ji)一體化(hua)結構，快速響應，靈敏(min)度(du)高(gao)，后續好的(de)(de)(de)結構簡單優點(dian)。

　　根(gen)據電(dian)(dian)磁(ci)推力的(de)產生原理，平(ping)面(mian)電(dian)(dian)機(ji)可分(fen)為三種(zhong)類型：變磁(ci)阻型、永磁(ci)同步(bu)型和感應型。永磁(ci)同步(bu)平(ping)面(mian)電(dian)(dian)機(ji)（PMSM）是近(jin)年(nian)來的(de)研究熱點。永磁(ci)同步(bu)平(ping)面(mian)電(dian)(dian)機(ji)具有直接接觸、輸出密(mi)(mi)度高、熱耗低、精度高等(deng)特點。它在(zai)現代精密(mi)(mi)和超精密(mi)(mi)加工設備中(zhong)具有廣闊的(de)應用前景，特別是在(zai)紫外(wai)光線中(zhong)的(de)領域。
