 永磁(ci)电(dian)(dian)机(ji)(ji)是(shi)一种转子(zi)自带(dai)永磁(ci)体的(de)电(dian)(dian)动机(ji)(ji)。它(ta)具有运行可靠、体积小(xiao)、质量(liang)轻、损耗小(xiao)、功率高等许多长处(chu)，属于超***电(dian)(dian)机(ji)(ji)。永磁(ci)电(dian)(dian)机(ji)(ji)的(de)节能作(zuo)用(yong)较(jiao)异步电(dian)(dian)机(ji)(ji)非常显着(zhe)，原因是(shi)什(shen)么呢？

首先，从规划和结构方法讲，永(yong)(yong)(yong)磁电(dian)(dian)机(ji)的(de)转(zhuan)(zhuan)子有稀土永(yong)(yong)(yong)磁磁钢，不需要定子供给感应(ying)电(dian)(dian)；永(yong)(yong)(yong)磁电(dian)(dian)机(ji)采用星形(xing)接线(xian)Y，异步电(dian)(dian)机(ji)4kw以上电(dian)(dian)机(ji)是△接法，Y接法比△接法电(dian)(dian)流小(xiao)；永(yong)(yong)(yong)磁电(dian)(dian)机(ji)运用的(de)材料不一(yi)样(yang)，绝缘等级高，在坚持功(gong)率不变的(de)前提下(xia)，能够缩小(xiao)一(yi)个机(ji)座号，铜耗(hao)削减，永(yong)(yong)(yong)磁电(dian)(dian)机(ji)控制功(gong)能良好，能够调整启(qi)动(dong)转(zhuan)(zhuan)矩，满意大转(zhuan)(zhuan)矩启(qi)动(dong)，然后(hou)缩小(xiao)电(dian)(dian)机(ji)型号，防止(zhi)大马拉小(xiao)车的(de)状况。

 其次，从(cong)实际运(yun)用状况看，永(yong)(yong)磁电(dian)(dian)(dian)机(ji)的(de)(de)空载(zai)(zai)电(dian)(dian)(dian)流只有异(yi)步电(dian)(dian)(dian)动(dong)机(ji)的(de)(de)1/3左右，削减消(xiao)耗；当(dang)拖动(dong)设备到(dao)达(da)稳定(ding)的(de)(de)流量(liang)、压力时(shi)(shi)，主动(dong)控制系统就会(hui)(hui)主动(dong)调理，电(dian)(dian)(dian)流会(hui)(hui)减小或者处(chu)于无功(gong)状态(tai)；永(yong)(yong)磁电(dian)(dian)(dian)机(ji)在运(yun)转(zhuan)过程(cheng)中，当(dang)负(fu)载(zai)(zai)发(fa)(fa)生变(bian)化(hua)时(shi)(shi)能(neng)效值(zhi)(zhi)能(neng)坚持(chi)不变(bian)，异(yi)步电(dian)(dian)(dian)机(ji)当(dang)负(fu)载(zai)(zai)发(fa)(fa)生变(bian)化(hua)时(shi)(shi)其能(neng)效值(zhi)(zhi)会(hui)(hui)发(fa)(fa)生变(bian)化(hua)；异(yi)步电(dian)(dian)(dian)机(ji)在负(fu)载(zai)(zai)到(dao)达(da)四(si)分之三时(shi)(shi)能(neng)效值(zhi)(zhi)不变(bian)，当(dang)负(fu)载(zai)(zai)小于70%时(shi)(shi)其能(neng)效值(zhi)(zhi)会(hui)(hui)直线下降。

***终，不(bu)管从客户实际运用(yong)(yong)作用(yong)(yong)仍是从实验(yan)作用(yong)(yong)看，咱们的(de)永磁电机节能作用(yong)(yong)***能够到达50%以上，***也在20%左右，节能作用(yong)(yong)显着。
