电机维修行业通常的(de)普通电(dian)(dian)机(ji)有(you)(you)单(dan)相电(dian)(dian)机(ji)、直流有(you)(you)刷(shua)、无刷(shua)电(dian)(dian)机(ji),伺服(fu)电(dian)(dian)机(ji)有(you)(you)永磁同步电(dian)(dian)机(ji),主轴电(dian)(dian)机(ji),带速度反馈的(de)高(gao)速电(dian)(dian)机(ji)。在电(dian)(dian)机(ji)维(wei)修实践中,经常会收到在别处二次维(wei)修的(de)伺服(fu)电(dian)(dian)机(ji),多为(wei)客户送(song)至普通电(dian)(dian)机(ji)修理处返修导(dao)致,感觉(jue)要对伺服(fu)电(dian)(dian)机(ji)与普通电(dian)(dian)机(ji)维(wei)修之间的(de)差别加以讲(jiang)述。
一、伺服(fu)电机需要专业(ye)设备维修
由于伺服电(dian)机(ji)(ji)的(de)结构是(shi)闭环(huan)反(fan)馈控制,这(zhei)个(ge)反(fan)馈部件我(wo)们叫做编(bian)码(ma)器(qi),用来测试(shi)(shi)电(dian)机(ji)(ji)速(su)度,位置,力矩功能,但通(tong)常(chang)编(bian)码(ma)器(qi)都是(shi)一一对(dui)应(ying),就是(shi)不(bu)(bu)同的(de)电(dian)机(ji)(ji)系列对(dui)应(ying)不(bu)(bu)同的(de)驱动器(qi),甚至同一系列不(bu)(bu)同功率电(dian)机(ji)(ji)对(dui)应(ying)不(bu)(bu)同的(de)驱动器(qi),不(bu)(bu)可以互(hu)换(huan)使(shi)用。通(tong)常(chang)在三(san)菱,安川,松下(xia)日系品牌上(shang)这(zhei)种情况尤为明(ming)显,厂家在设计时为了自(zi)身利益的(de)考虑,通(tong)讯协(xie)议(yi)也(ye)不(bu)(bu)公(gong)开,这(zhei)就直接导(dao)致了维(wei)修试(shi)(shi)机(ji)(ji)成本过(guo)高,普通(tong)电(dian)机(ji)(ji)维(wei)修一般的(de)工控维(wei)修公(gong)司无法做到(dao);
二、伺(si)服电机故障类型远多于普通电机
普通电机由于结(jie)构简单,通常(chang)都是些机修(xiu)(xiu),机加,焊补,绕线(xian)等处理,对于电子维修(xiu)(xiu)要求为0;
而(er)伺服电机除了这些(xie)以(yi)外,编码(ma)器(qi)故障也(ye)需要处理,信号衰减(jian),通讯中断,速度不(bu)稳定,丢脉冲通常都和编码(ma)器(qi)电路板电子(zi)元(yuan)件(jian),IC片有关,必须具备电子(zi)维修技能才可以(yi)处理。
三、伺(si)服电机维修人员(yuan)须具备一定的工程调(diao)试经验
伺(si)服(fu)电(dian)机(ji)(ji)维(wei)(wei)修(xiu)(xiu)其实与伺(si)服(fu)驱动(dong)器的(de)(de)维(wei)(wei)修(xiu)(xiu)是分(fen)不(bu)开的(de)(de),客(ke)户(hu)通常(chang)会(hui)因为一个(ge)故障报警(jing)判(pan)(pan)断是伺(si)服(fu)电(dian)机(ji)(ji)坏了(le)(le),更多的(de)(de)时候会(hui)联(lian)系维(wei)(wei)修(xiu)(xiu)方要(yao)求给(ji)予判(pan)(pan)断,这就(jiu)要(yao)求我们不(bu)但要(yao)具(ju)备维(wei)(wei)修(xiu)(xiu)伺(si)服(fu)电(dian)机(ji)(ji)机(ji)(ji)修(xiu)(xiu)电(dian)修(xiu)(xiu)能力外,还需要(yao)对设备有所了(le)(le)解,如各(ge)品牌(pai)伺(si)服(fu)驱动(dong)器增益的(de)(de)调整,限位设置,电(dian)子齿轮比等(deng),修(xiu)(xiu)复后有的(de)(de)还要(yao)给(ji)予客(ke)户(hu)提出配(pei)合要(yao)求,例如多圈绝对值编(bian)码器的(de)(de)绝对相对位置清零等(deng)工作。
所以判断维修单位是否可以维修伺服电机,需要看他是否有配套的测试平台,是不是具备电子维修能(neng)力,通(tong)常(chang)这样的公司(si)应该具备(bei)一定的电子维修(xiu)背景,同时(shi)(shi)具备(bei)机修(xiu)能(neng)力,还要看它(ta)是否有自己(ji)的机加(jia)焊接设备(bei)和操作(zuo)能(neng)力,或有良好(hao)的合作(zuo)方,人员是否同时(shi)(shi)有机修(xiu)理论(lun)支持,机修(xiu)常(chang)识(shi)经验也很重要。
