2094-PRS7伺服模块

通电后电动机不转有嗡嗡声

1.故障原因①转子绕组有断路（一相断线）或电源一相失电；②绕组引出线始末端接错或绕组内部接反；③电源回路接点松动，接触电阻大；④电动机负载过大或转子卡住；⑤电源电压过低；⑥小型电动机装配太紧或轴承内油脂过硬；⑦轴承卡住。

2.故障排除①查明断点予以修复；②检查绕组极性；判断绕组末端是否正确；③紧固松动的接线螺丝，用万用表判断各接头是否假接，予以修复；④减载或查出并机械故障，⑤检查是否把规定的面接法误接；是否由于电源导线过细使压降过大，予以纠正，⑥重新装配使之灵活；更换合格油

脂；⑦修复轴承。

需要控制的电机及变频器自身

1）电机的极数。一般电机极数以不多于(极为宜，否则变频器容量就要适当加大。

2）转矩特性、临界转矩、加速转矩。在同等电机功率情况下，相对于高过载转矩模式，变频器规格可以降额选取。3）电磁兼容性。为减少主电源干扰，使用时可在中间电路或变频器输入电路中增加电抗器，或安装前置隔离变压器。一般当电机与变频器距离超过50m时，应在它们中间串入电抗器、滤波器或采用屏蔽防护电缆
