伺(si)服(fu)电(dian)(dian)(dian)(dian)机选型的(de)(de)(de)(de)注(zhu)意事项(xiang)1、有(you)些(xie)系(xi)统如传送(song)装(zhuang)置(zhi)(zhi)，升降装(zhuang)置(zhi)(zhi)等要(yao)求伺(si)服(fu)电(dian)(dian)(dian)(dian)机能(neng)尽快(kuai)停车，而(er)在故障、急(ji)停、电(dian)(dian)(dian)(dian)源断电(dian)(dian)(dian)(dian)时伺(si)服(fu)器没有(you)再(zai)生(sheng)制(zhi)(zhi)动(dong)，无法对电(dian)(dian)(dian)(dian)机减速。同时系(xi)统的(de)(de)(de)(de)机械(xie)惯量又较(jiao)大，这时对动(dong)态制(zhi)(zhi)动(dong)器的(de)(de)(de)(de)要(yao)依据负载的(de)(de)(de)(de)轻重、电(dian)(dian)(dian)(dian)机的(de)(de)(de)(de)工作速度(du)等进行(xing)选择。2、有(you)些(xie)系(xi)统要(yao)维持机械(xie)装(zhuang)置(zhi)(zhi)的(de)(de)(de)(de)静止位置(zhi)(zhi)，需电(dian)(dian)(dian)(dian)机提供较(jiao)大的(de)(de)(de)(de)输出转矩，且停止的(de)(de)(de)(de)时间较(jiao)长。如果(guo)使用伺(si)服(fu)的(de)(de)(de)(de)自锁功能(neng)，往往会(hui)造成电(dian)(dian)(dian)(dian)机过热或放大器过载，这种情况就(jiu)要(yao)选择带(dai)电(dian)(dian)(dian)(dian)磁(ci)制(zhi)(zhi)动(dong)的(de)(de)(de)(de)电(dian)(dian)(dian)(dian)机。3、有(you)的(de)(de)(de)(de)伺(si)服(fu)驱动(dong)器有(you)内置(zhi)(zhi)的(de)(de)(de)(de)再(zai)生(sheng)制(zhi)(zhi)动(dong)单元，但当再(zai)生(sheng)制(zhi)(zhi)动(dong)较(jiao)频繁时，可能(neng)引起(qi)直流母线电(dian)(dian)(dian)(dian)压过高，这时需另配(pei)再(zai)生(sheng)制(zhi)(zhi)动(dong)电(dian)(dian)(dian)(dian)阻。再(zai)生(sheng)制(zhi)(zhi)动(dong)电(dian)(dian)(dian)(dian)阻是(shi)否需要(yao)另配(pei)，配(pei)多大，可参照相应(ying)样本的(de)(de)(de)(de)使用说明来(lai)配(pei)。4、如果(guo)选择了(le)带(dai)电(dian)(dian)(dian)(dian)磁(ci)制(zhi)(zhi)动(dong)器的(de)(de)(de)(de)伺(si)服(fu)电(dian)(dian)(dian)(dian)机，电(dian)(dian)(dian)(dian)机的(de)(de)(de)(de)转动(dong)惯量会(hui)增大，计算转矩时要(yao)进行(xing)考虑(lv)。

伺(si)(si)服(fu)(fu)电(dian)机(ji)(ji)(ji)(ji)(ji)编(bian)码器调零(ling)(ling)(ling)的(de)(de)(de)含义1、伺(si)(si)服(fu)(fu)电(dian)机(ji)(ji)(ji)(ji)(ji)的(de)(de)(de)控(kong)(kong)(kong)制(zhi)原理是(shi)采用(yong)矢量控(kong)(kong)(kong)制(zhi)方式(shi)来控(kong)(kong)(kong)制(zhi)和(he)驱动的(de)(de)(de)，因(yin)此(ci)将编(bian)码器在电(dian)机(ji)(ji)(ji)(ji)(ji)轴(zhou)上的(de)(de)(de)安(an)(an)装(zhuang)(zhuang)角度(du)称为零(ling)(ling)(ling)点(dian)(dian)。这里需要(yao)(yao)(yao)注意的(de)(de)(de)一(yi)(yi)点(dian)(dian)是(shi)不(bu)同(tong)(tong)系列的(de)(de)(de)伺(si)(si)服(fu)(fu)电(dian)机(ji)(ji)(ji)(ji)(ji)其安(an)(an)装(zhuang)(zhuang)的(de)(de)(de)角度(du)值不(bu)同(tong)(tong)。2、伺(si)(si)服(fu)(fu)电(dian)机(ji)(ji)(ji)(ji)(ji)零(ling)(ling)(ling)点(dian)(dian)误差大，电(dian)机(ji)(ji)(ji)(ji)(ji)的(de)(de)(de)无功电(dian)流也会增(zeng)大，转(zhuan)矩(ju)不(bu)会随着电(dian)流增(zeng)大而增(zeng)大，因(yin)此(ci)电(dian)机(ji)(ji)(ji)(ji)(ji)会表现无力，也就(jiu)是(shi)转(zhuan)矩(ju)不(bu)够，甚至出现电(dian)机(ji)(ji)(ji)(ji)(ji)无法运(yun)行的(de)(de)(de)情(qing)况，一(yi)(yi)般(ban)情(qing)况下，不(bu)建议(yi)对(dui)(dui)伺(si)(si)服(fu)(fu)电(dian)机(ji)(ji)(ji)(ji)(ji)的(de)(de)(de)编(bian)码的(de)(de)(de)安(an)(an)装(zhuang)(zhuang)位(wei)置(zhi)和(he)角度(du)进行调整。3、伺(si)(si)服(fu)(fu)电(dian)机(ji)(ji)(ji)(ji)(ji)编(bian)码器调整零(ling)(ling)(ling)位(wei)可(ke)以通过换(huan)编(bian)码器来实现，如(ru)果要(yao)(yao)(yao)换(huan)轴(zhou)承，要(yao)(yao)(yao)对(dui)(dui)编(bian)码器进行一(yi)(yi)定的(de)(de)(de)拆除安(an)(an)装(zhuang)(zhuang)，拆之前对(dui)(dui)编(bian)码的(de)(de)(de)各部件(jian)座做一(yi)(yi)个简单的(de)(de)(de)位(wei)点(dian)(dian)标(biao)记，以防安(an)(an)装(zhuang)(zhuang)不(bu)到位(wei)而导(dao)致故(gu)障出现。上海SV-MM11伺(si)(si)服(fu)(fu)电(dian)机(ji)(ji)(ji)(ji)(ji)电(dian)流尽(jin)管术语“ 伺(si)(si)服(fu)(fu)电(dian)动机(ji)(ji)(ji)(ji)(ji)”通常(chang)用(yong)于表示适用(yong)于闭环控(kong)(kong)(kong)制(zhi)系统(tong)的(de)(de)(de)电(dian)动机(ji)(ji)(ji)(ji)(ji)，但伺(si)(si)服(fu)(fu)电(dian)动机(ji)(ji)(ji)(ji)(ji)不(bu)是(shi)特定的(de)(de)(de)电(dian)动机(ji)(ji)(ji)(ji)(ji)类别。

伺(si)服(fu)电(dian)机(ji)线缆选择方法如下：

线(xian)缆材(cai)(cai)(cai)质(zhi)。伺服电机线(xian)缆材(cai)(cai)(cai)质(zhi)要(yao)求特(te)别(bie)高，需(xu)要(yao)选(xuan)择具(ju)有(you)耐高温、抗(kang)老化(hua)、耐油、耐磨、抗(kang)干扰等特(te)性的材(cai)(cai)(cai)料。常用(yong)的线(xian)缆材(cai)(cai)(cai)质(zhi)有(you)PUR、PVC、TPU、PE等，其中PUR材(cai)(cai)(cai)料是所(suo)有(you)材(cai)(cai)(cai)质(zhi)中性能棒、使(shi)用(yong)寿命长的材(cai)(cai)(cai)料。

导线数量(liang)。伺服电(dian)机线缆的(de)导线数量(liang)要(yao)与使用(yong)的(de)伺服控制器匹配。一(yi)般情况下(xia)，伺服电(dian)机线缆的(de)导线数量(liang)是22根或24根（包括屏蔽(bi)层和(he)非屏蔽(bi)层导线）。

屏(ping)蔽(bi)等(deng)(deng)级(ji)。伺(si)服(fu)电机线(xian)(xian)缆的屏(ping)蔽(bi)等(deng)(deng)级(ji)应该根(gen)据(ju)伺(si)服(fu)电机所处的环境和噪声等(deng)(deng)级(ji)来选择。一般来说(shuo)，屏(ping)蔽(bi)等(deng)(deng)级(ji)越高，线(xian)(xian)缆的抗干(gan)扰(rao)能力(li)就(jiu)越强(qiang)。

1.检查电(dian)(dian)(dian)机(ji)参数设置如(ru)(ru)果伺服(fu)电(dian)(dian)(dian)机(ji)嗡嗡响的原因是电(dian)(dian)(dian)机(ji)参数设置不合(he)适，可以根据电(dian)(dian)(dian)机(ji)的型号和使用(yong)环境进行调整。比如(ru)(ru)增加或(huo)减小增益参数、调整积分(fen)参数和微分(fen)参数等，使得电(dian)(dian)(dian)机(ji)控制更加稳定。

2.检查机(ji)(ji)械(xie)结(jie)构如果伺服电机(ji)(ji)嗡嗡响的原因是机(ji)(ji)械(xie)结(jie)构松动(dong)，需要仔细检查机(ji)(ji)械(xie)结(jie)构，确保所有部件都紧固牢固，避免产生震动(dong)和噪音。

3.检(jian)(jian)查传感器如果(guo)伺(si)(si)服(fu)电(dian)机(ji)嗡嗡响的原因(yin)是传感器故(gu)障，需要(yao)检(jian)(jian)查传感器是否存在(zai)故(gu)障，并及(ji)时(shi)(shi)更换或修复。总之，伺(si)(si)服(fu)电(dian)机(ji)嗡嗡响的原因(yin)多种(zhong)多样(yang)，需要(yao)根据具(ju)体情况选择(ze)合适的解决方案。同时(shi)(shi)，使用伺(si)(si)服(fu)电(dian)机(ji)时(shi)(shi)要(yao)注意(yi)选择(ze)合适的型号和参(can)数，以及(ji)保持机(ji)械结(jie)构的紧固(gu)稳定，避免产生噪音和故(gu)障。伺(si)(si)服(fu)电(dian)机(ji)在(zai)食(shi)品包(bao)(bao)装行业，比(bi)如说薯条等(deng)零(ling)食(shi)的真(zhen)空包(bao)(bao)装生产等(deng)等(deng)。

伺(si)服(fu)电(dian)机和同步(bu)电(dian)机的区别：

控(kong)制(zhi)方式不同：同步(bu)电(dian)机通常采用变(bian)频器进行控(kong)制(zhi)。变(bian)频器输出(chu)的(de)(de)频率和电(dian)压(ya)可以控(kong)制(zhi)同步(bu)电(dian)机的(de)(de)转速(su)和输出(chu)功率。伺服电(dian)机则需(xu)要(yao)采用闭(bi)环(huan)控(kong)制(zhi)方式。伺服电(dian)机通过编码器或传感器提供的(de)(de)位置反馈信号，实现控(kong)制(zhi)系统对电(dian)机实时控(kong)制(zhi)。

扭(niu)矩(ju)(ju)(ju)特性(xing)不(bu)(bu)同(tong)：同(tong)步电(dian)(dian)(dian)机(ji)在满载运(yun)行时(shi)，其输出扭(niu)矩(ju)(ju)(ju)基(ji)本上是(shi)一个(ge)恒定值，不(bu)(bu)会发(fa)生(sheng)扭(niu)矩(ju)(ju)(ju)波动(dong)。伺(si)服(fu)(fu)电(dian)(dian)(dian)机(ji)则具有更灵活的扭(niu)矩(ju)(ju)(ju)调(diao)节曲线，可以(yi)随时(shi)调(diao)整输出的扭(niu)矩(ju)(ju)(ju)大小(xiao)和方向1。精度(du)要(yao)求不(bu)(bu)同(tong)：同(tong)步电(dian)(dian)(dian)机(ji)本身稳定性(xing)较高，精度(du)相(xiang)对较低。伺(si)服(fu)(fu)电(dian)(dian)(dian)机(ji)则适用(yong)于对定位(wei)和精度(du)要(yao)求较高的应(ying)用(yong)，其控(kong)(kong)制(zhi)系(xi)统可以(yi)实(shi)现(xian)高精度(du)的位(wei)置(zhi)和速度(du)控(kong)(kong)制(zhi)，从而更有效地实(shi)现(xian)制(zhi)造过程的监(jian)控(kong)(kong)和优化。伺(si)服(fu)(fu)电(dian)(dian)(dian)机(ji)的工作(zuo)原理(li)基(ji)于闭环(huan)控(kong)(kong)制(zhi)系(xi)统。控(kong)(kong)制(zhi)器接收编码器反馈(kui)的位(wei)置(zhi)和速度(du)信息(xi)，并与目标值进行比较。英(ying)威腾MH860伺(si)服(fu)(fu)电(dian)(dian)(dian)机(ji)

伺服电动(dong)(dong)机与普通电动(dong)(dong)机的区别如下：

伺(si)服(fu)电机(ji)(ji)(ji)(ji)(ji)能(neng)够(gou)做(zuo)到控制，可以控制让转(zhuan)(zhuan)多(duo)少(shao)就转(zhuan)(zhuan)多(duo)少(shao)，而(er)普(pu)(pu)通(tong)(tong)电机(ji)(ji)(ji)(ji)(ji)转(zhuan)(zhuan)速过(guo)快(kuai)，扭(niu)力过(guo)小(xiao)，自(zi)身没有(you)反馈，所以没办法做(zuo)到的(de)控制。伺(si)服(fu)电机(ji)(ji)(ji)(ji)(ji)是经过(guo)经过(guo)反应编(bian)码器的(de)同(tong)步信号(hao)知道转(zhuan)(zhuan)子改换(huan)的(de)磁场(chang)，所以能(neng)够(gou)完成控制，但是普(pu)(pu)通(tong)(tong)电机(ji)(ji)(ji)(ji)(ji)没有(you)同(tong)步信号(hao)要(yao)(yao)求。伺(si)服(fu)电机(ji)(ji)(ji)(ji)(ji)的(de)结(jie)构(gou)是闭(bi)环反馈控制，需要(yao)(yao)使用(yong)伺(si)服(fu)驱动(dong)(dong)(dong)器，但是普(pu)(pu)通(tong)(tong)电动(dong)(dong)(dong)机(ji)(ji)(ji)(ji)(ji)结(jie)构(gou)相对来说比较(jiao)简单。伺(si)服(fu)电机(ji)(ji)(ji)(ji)(ji)的(de)价(jia)格通(tong)(tong)常要(yao)(yao)比普(pu)(pu)通(tong)(tong)电动(dong)(dong)(dong)机(ji)(ji)(ji)(ji)(ji)更(geng)贵，而(er)且故障(zhang)类型(xing)更(geng)多(duo)，维(wei)修更(geng)麻烦。普(pu)(pu)通(tong)(tong)电机(ji)(ji)(ji)(ji)(ji)的(de)应用(yong)场(chang)合主要(yao)(yao)是电动(dong)(dong)(dong)玩具、剃(ti)须刀(dao)之类的(de)普(pu)(pu)通(tong)(tong)电器，而(er)伺(si)服(fu)电机(ji)(ji)(ji)(ji)(ji)需求经过(guo)电机(ji)(ji)(ji)(ji)(ji)后端的(de)传感器及编(bian)码器反应速度、方位(wei)或力矩参(can)考值给配(pei)套驱动(dong)(dong)(dong)器，再(zai)由驱动(dong)(dong)(dong)器实(shi)时调整驱动(dong)(dong)(dong)电流按(an)用(yong)户指定值来操控电机(ji)(ji)(ji)(ji)(ji)旋(xuan)转(zhuan)(zhuan)。上海5.5KW伺(si)服(fu)电机(ji)(ji)(ji)(ji)(ji)尺寸(cun)
