What are the common control unit faults and their solutions for motor motor rotor automatic core punching machine?
For the common control unit faults of motor motor rotor automatic core punching machine and its solutions, the following are some key points:
1、The motor does not start:
Cause: the power supply may not be connected, overload protector tripped or control circuit failure.
Solution: check whether the power supply is normal, reset the overload protector, check whether the wiring and components of the control circuit are normal.
2、Motor rattling:
Cause: may be bearing wear, rotor and stator clearance is too small or improper installation.
Solution: Check the internal parts of the motor, replace the bearings if necessary, and adjust the clearance between the rotor and stator.
3、Motor overheating:
Cause: may be overloaded, poor ventilation or high ambient temperature.
Solution: Check whether the load exceeds the rated value of the motor, ensure that the motor is well ventilated, and improve the ambient temperature if necessary.
4、Abnormal current:
Reason: may be a short circuit, ground fault or phase imbalance.
Solution: Check whether the motor winding is short-circuited or grounded, measure the phase current, ensure that the current balance between the phases.
5、Control system failure:
Reason: It may be sensor failure, PLC program error or signal interference.
Solution: check whether the sensor is working properly, debug the PLC program, remove the source of signal interference.
6、Starting difficulties:
Reason: may be insufficient voltage, excessive starting current or mechanical jamming.
Solution: Check the power supply voltage to ensure that the normal range, check whether the mechanical part of the phenomenon of hysteresis.
7、Frequent tripping:
Cause: may be current overload, short circuit or equipment aging.
Solution: check the load, troubleshoot short-circuit faults, regular maintenance and replacement of aging equipment.
Through the above fault analysis and solutions, you can effectively improve the stability and reliability of the motor motor rotor automatic core punching machine operation.

Case: unstable sensor signals lead to decreased production efficiency
Failure phenomenon: a factory's motor motor rotor automatic core punching machine in the production process of the sensor failure, resulting in the machine can not work properly. Failure to show that the sensor signal is not stable, affecting the precise control of the machine and production efficiency.
Solution:
Check the status of the sensor: the technicians checked the sensor, including the power supply, the connection line and the working status of the sensor itself. Ensure that the power supply of the sensor is normal and there is no short-circuit phenomenon.
Line check and repair: the connection line from the sensor to the controller was carefully checked, and it was found that some of the lines were worn out and had poor contact due to long time use. Technicians have repaired and replaced these lines to ensure the stability of signal transmission.
Electromagnetic interference treatment: Considering the possible electromagnetic interference problem, the technicians evaluated the electromagnetic environment around the sensor and took corresponding shielding measures, such as the use of shielded wires and increased grounding measures to reduce the impact of interference on the sensor signal.
Sensor Replacement: After eliminating the problems of wiring and electromagnetic interference, if the sensor signal is still unstable, the technicians decided to replace the sensor. After the replacement, the sensor signal returns to normal, the machine runs stably, and the production efficiency and product quality are significantly improved.
Results: Through the implementation of the above solutions, the sensor failure has been effectively solved, and the automatic core punching machine has resumed normal operation. The production efficiency and product quality of the factory were guaranteed, and the economic loss caused by the failure was reduced.
