Common faults in the motor of the advertising engraving machine?

1. Transfer: When the engraving machine is used for the first time, the motor reverses. At this point, we need to check whether the motor line is inserted incorrectly or because of the inversion caused by the missing, or the UVW end of the output is exchanged, so as to do the relevant troubleshooting work.

2, powerless: After using for a period of time, the motor of the engraving machine has no strength, which may be due to a short circuit of the cable or the motor has no strength due to lack of phase. At this point we need to do the relevant inspection work.

3. Sound: When the motor is overloaded, or due to component failure inside the motor, abnormal sound will occur. At this point, the staff does not need to panic. What needs to be done is to treat them calmly and wait for the professionals to come to the repair.

4. Hot: After the motor reports the fault signal, we can observe and test because the circulating water is less than the lowest liquid level, which causes the motor to become hot, which causes the engraving machine to operate normally.
