IC693CPU360RR 运行中的电动机,如果电流不超过该电动机的额定电流就说明电路上基本没什么问题,如果没有改变原负荷,要检测电压是否于额定电压,一般380V就正负5%正常。看环境温度是否过高。轴承是否缺油。散热风扇是否损坏。
(1)负载过大。应减轻负载或更换较大容量的电动机。
(2)两相运转。应检查熔丝是否熔断、开关接触点的接触是否良好,排除故障;
(3)电动机风道阻塞。应清除风道灰尘或油垢;
(4)环境温度升高。应采取降温措施;
(5)定子绕组匝间或相间短路。用兆欧表或万用表检查二相绕组间的绝缘电阻;用电流平衡法检查三相绕组电流,电流大的相为短路相,也可用短路侦察器检查绕组匝间是否短路;
(6)定子绕组接地。可用万用表或指示灯检查,电阻为零的为接地相;
(7)电源电压过低或过高。用万用表的电压档或电压表检查电动机输入端电源电压。
