步(bu)(bu)(bu)进(jin)电(dian)(dian)(dian)机(ji)(ji)(ji)(ji)是一(yi)种将电(dian)(dian)(dian)脉(mai)冲(chong)信号转(zhuan)(zhuan)换成相应(ying)角(jiao)位(wei)(wei)(wei)移或线位(wei)(wei)(wei)移的(de)电(dian)(dian)(dian)动(dong)(dong)机(ji)(ji)(ji)(ji)。每输(shu)入一(yi)个脉(mai)冲(chong)信号，转(zhuan)(zhuan)子(zi)就转(zhuan)(zhuan)动(dong)(dong)一(yi)个角(jiao)度(du)或前(qian)进(jin)一(yi)步(bu)(bu)(bu)，其(qi)输(shu)出的(de)角(jiao)位(wei)(wei)(wei)移或线位(wei)(wei)(wei)移与输(shu)入的(de)脉(mai)冲(chong)数成正比(bi)，转(zhuan)(zhuan)速(su)与脉(mai)冲(chong)频率(lv)成正比(bi)。因此，步(bu)(bu)(bu)进(jin)电(dian)(dian)(dian)动(dong)(dong)机(ji)(ji)(ji)(ji)又称脉(mai)冲(chong)电(dian)(dian)(dian)动(dong)(dong)机(ji)(ji)(ji)(ji)。与伺服电(dian)(dian)(dian)机(ji)(ji)(ji)(ji)相比(bi)较，步(bu)(bu)(bu)进(jin)电(dian)(dian)(dian)机(ji)(ji)(ji)(ji)可以在开环条件(jian)下即可实现位(wei)(wei)(wei)置工(gong)作模式(shi)的(de)控(kong)制(zhi)(zhi)(zhi)电(dian)(dian)(dian)机(ji)(ji)(ji)(ji)，因其(qi)控(kong)制(zhi)(zhi)(zhi)与驱动(dong)(dong)简单，且(qie)(qie)成本低廉，是目前(qian)应(ying)用(yong)最广泛的(de)控(kong)制(zhi)(zhi)(zhi)电(dian)(dian)(dian)机(ji)(ji)(ji)(ji)之(zhi)一(yi)。 瑞宝电(dian)(dian)(dian)器(qi)(qi)在步(bu)(bu)(bu)进(jin)电(dian)(dian)(dian)机(ji)(ji)(ji)(ji)领域(yu)的(de)研发(fa)方向主要(yao)面向工(gong)业(ye)设(she)备(bei)、工(gong)程机(ji)(ji)(ji)(ji)械、商业(ye)机(ji)(ji)(ji)(ji)器(qi)(qi)、通讯设(she)备(bei)、医疗设(she)备(bei)等(deng)领域(yu)，在近20年的(de)研发(fa)和生(sheng)产实践中(zhong)，对不(bu)(bu)同(tong)领域(yu)的(de)步(bu)(bu)(bu)进(jin)电(dian)(dian)(dian)机(ji)(ji)(ji)(ji)设(she)计与控(kong)制(zhi)(zhi)(zhi)要(yao)素(su)有丰富的(de)认知(zhi)与产品(pin)管理能力，目前(qian)不(bu)(bu)仅有近100个系列(lie)，略6000个以上规格的(de)产品(pin)，而且(qie)(qie)可以快(kuai)速(su)根据客(ke)户应(ying)用(yong)工(gong)况与要(yao)求展开订(ding)制(zhi)(zhi)(zhi)服务(wu)。 购买(mai)建议：若(ruo)电(dian)(dian)(dian)机(ji)(ji)(ji)(ji)工(gong)作速(su)度(du)低于800RPM且(qie)(qie)位(wei)(wei)(wei)置精度(du)要(yao)求较高(gao)，输(shu)出转(zhuan)(zhuan)矩较大但转(zhuan)(zhuan)矩脉(mai)动(dong)(dong)较少时，请考虑使合(he)混合(he)式(shi)步(bu)(bu)(bu)进(jin)电(dian)(dian)(dian)机(ji)(ji)(ji)(ji)；如果速(su)度(du)较高(gao)（低于3000RPM）且(qie)(qie)输(shu)出扭矩不(bu)(bu)高(gao)时，请考虑使用(yong)永磁步(bu)(bu)(bu)进(jin)电(dian)(dian)(dian)机(ji)(ji)(ji)(ji)。

无刷(shua)直流(liu)电(dian)(dian)动机(ji)（BLDC）是(shi)(shi)一种由直流(liu)电(dian)(dian)压(ya)供(gong)电(dian)(dian)的(de)(de)(de)电(dian)(dian)动机(ji)，以(yi)电(dian)(dian)子(zi)方式换向，而不是(shi)(shi)像(xiang)传统直流(liu)电(dian)(dian)动机(ji)那样由电(dian)(dian)刷(shua)换向。与(yu)传统直流(liu)电(dian)(dian)机(ji)相(xiang)(xiang)比(bi)，最突出的(de)(de)(de)区(qu)别(bie)是(shi)(shi)换向器(qi)的(de)(de)(de)类型(xing)，直流(liu)无刷(shua)电(dian)(dian)机(ji)采用(yong)(yong)霍尔(er)传感器(qi)，能(neng)够(gou)以(yi)电(dian)(dian)子(zi)方式反馈(kui)转子(zi)位置信息。在(zai)(zai)搭配编(bian)码器(qi)后，BLDC还可以(yi)在(zai)(zai)需要精准定位的(de)(de)(de)应用(yong)(yong)场(chang)合中(zhong)使用(yong)(yong)。无刷(shua)电(dian)(dian)机(ji)的(de)(de)(de)结(jie)构(gou)可以(yi)是(shi)(shi)转子(zi)在(zai)(zai)里(li)面（“内转子(zi)”），也可以(yi)是(shi)(shi)转子(zi)在(zai)(zai)绕(rao)组的(de)(de)(de)外面（ "外转子(zi) "）。无刷(shua)电(dian)(dian)机(ji)中(zhong)使用(yong)(yong)的(de)(de)(de)绕(rao)组数量被(bei)称为(wei)相(xiang)(xiang)数。尽管无刷(shua)电(dian)(dian)机(ji)可以(yi)用(yong)(yong)不同的(de)(de)(de)相(xiang)(xiang)数构(gou)造(zao)，但(dan)三(san)相(xiang)(xiang)无刷(shua)电(dian)(dian)机(ji)是(shi)(shi)最常见的(de)(de)(de)。 瑞宝电(dian)(dian)器(qi)通过(guo)优化三(san)相(xiang)(xiang)BLDC的(de)(de)(de)设计和结(jie)构(gou)，使电(dian)(dian)机(ji)具(ju)有优越(yue)的(de)(de)(de)调(diao)速性(xing)能(neng)，表(biao)现在(zai)(zai)控制性(xing)能(neng)好、调(diao)速范围宽、低速性(xing)能(neng)好、运行平稳、效率高，应用(yong)(yong)场(chang)合从工业到民用(yong)(yong)极其(qi)广泛。
