弹簧试验机电机de常见故障分析
点击次数：162 发布时间：2014-12-7
一般在使用中会出现两种情况，一种是弹簧试验机的电动机在通电后有“嗡嗡”声，断电后手摸电动机外壳发烫，则是电动机的轴承不良或电动机的主绕组部分短路、起动绕组开路、起动部件失效。
Generally in use will occur in two situations, one is the motor spring testing machine has a "buzz" sound in electricity, power hand motor casing hot, it is the main winding short circuit,motor bearing failure or the starting of the motor winding, starting component failure.
若是弹簧试验机安装的是单向异步电动机，通电后呈现不转变毛病的话，应细心听听弹簧试验机电动机在通电后是不是有“嗡嗡”的电磁声，还应在堵截电源后，用手接触电动机的外壳是不是发烫。若电动机无“嗡嗡”的电磁声，也无温升，则阐明电动机未通电，应运用万用表电阻档进一步检测电源输入线路及电动机各绕组的直流电阻值，看一下是不是有开路毛病。
If the spring testing machine installation is one-way asynchronous motor, power is not changeproblem, should carefully listen to the spring testing machine motor Is it right?"Electromagnetic hum" in the electricity, also should be cut off the power, hand contact with the motor shell is not hot. Electromagnetic sound if the motor without the "buzzing", notemperature rise, illustrates the motor without electricity, should use the multimeter resistance profile further detection of DC resistance power input line and motor windings values, see theIs it right? Open circuit fault.
