Analysis of the cause of servo motor failure (5)
Eight, the motor does not turn after the power is turned on.
1. Cause of failure
1 The rotor winding has an open circuit (one phase disconnection) or the power supply loses phase;
2 The winding lead wire is connected to the wrong end or the inner winding is reversed;
3 power circuit contacts are loose, touch resistance is large;
4 the motor load is too large or the rotor is stuck;
5 power supply voltage is too low;
6 small motor installation is too tight or the grease inside the bearing is too hard;
7 bearings are stuck.
2. Troubleshooting
1 to identify the breakpoint to be amended;
2 Check the winding polarity; determine whether the winding end is correct;
3 Fasten the loose connecting screws and use a multimeter to judge whether the joints are falsely connected and correct them;
4loading or detecting and eliminating mechanical failure,
5 Check if the ruled face connection method is misconnected; if the power supply wire is too thin to make the pressure drop too large, correct it.
6 from the beginning to make it flexible; replace qualified grease;
7 Correct the bearing.
