oursThree-phase asynchronous motorIf it is used after long-term idle, repair and maintenance, then it must go through the necessary inspection and test before use. Follow todayMori machineA brief look at the insulation test.

       The basic test items are insulation test, no-load current measurement and so on. In experimentThree-phase asynchronous motorFirst, we need to carry out a routine inspection of the motor. First of all, check the assembly quality of the motor, whether the fastening screws in each part are tightened, whether the rotor is flexible, and whether the mark and position of the lead line are correct. After these conditions of the motor are confirmed, the connection piece of the lead wire of the stator winding can be removed, so that the six ends of the winding are independent, and then the insulation test is carried out.

       Insulation test includes insulation resistance measurement, insulation withstand voltage test. We first take the measurement of insulation resistance as an example, you can use a megohm meter to measure the insulation resistance between the phase of the stator winding and the insulation resistance between each relative shell, and the rotor winding should also check the insulation resistance between the rotor winding and the winding to the shell. The measured resistance values are all in0.5Above megohm, the insulation is good. When measuring, for500VThe following motors are used500VMegohm meter, yes500~1000VThe motor available1000VMegohm meter.
