近日
，北京和利時電機公司獲“隱極式永磁同步電機的調速控製係統和方法”的發明專利（專利號200910090386.9）。

   隨著稀土永磁材料

、電力電子技術以及電機控製理論等的快速發展，永磁同步電機（PMSM）以其高轉矩/慣性比
、高功率密度、高效率
、牢固性和維修性好等優點，在紡織

、化纖、數控機床、工(gong)業(ye)機(ji)器(qi)人(ren)以(yi)及(ji)航(hang)空(kong)航(hang)天(tian)等(deng)領(ling)域(yu)得(de)到(dao)日(ri)益(yi)廣(guang)泛(fan)的(de)應(ying)用(yong)。根(gen)據(ju)永(yong)磁(ci)同(tong)步(bu)電(dian)機(ji)的(de)結(jie)構(gou)不(bu)同(tong)，永(yong)磁(ci)同(tong)步(bu)電(dian)機(ji)分(fen)為(wei)凸(tu)極(ji)式(shi)和(he)隱(yin)極(ji)式(shi)兩(liang)種(zhong)。在(zai)工(gong)業(ye)應(ying)用(yong)場(chang)合(he)，大(da)部(bu)分(fen)的(de)永(yong)磁(ci)同(tong)步(bu)電(dian)機(ji)為(wei)隱(yin)極(ji)式(shi)電(dian)機(ji)。當(dang)采(cai)用(yong)正(zheng)弦(xian)波(bo)電(dian)流(liu)控(kong)製(zhi)方(fang)案(an)實(shi)現(xian)速(su)度(du)控(kong)製(zhi)時(shi)
