How to analyze and troubleshoot faults in motor rotor slot paper machines?

To analyze and troubleshoot faults in motor rotor slot paper machines, follow these steps:

1、 electrical fault analysis:

Frequency converter can not start: check whether the load is not jammed or blocked, and whether the frequency converter itself is faulty.

Motor heating abnormality: check whether there is a line fault inside the motor or internal motor failure, resulting in abnormal current.

Operation failure: check whether acceleration and deceleration is normal action, and whether there are problems such as poor line contact or communication interference.

2、mechanical failure analysis:

Bearing heat: check whether the bearing is worn or lack of lubrication due to long time running, need to replace the bearing or add lubricant.

Abnormal sound of equipment rotation: check if the equipment has periodic sound and observe if there is any mechanical periodic problem. It may be necessary to adjust or replace the relevant mechanical components.

3、Motor does not rotate fault:

Check whether there is power access, exclude the fault alarm, check whether there is any problem with the motor itself and the frequency converter.

4、Motor vibration and loud but can not turn:

Check whether the motor and the frequency converter are faulty, and whether the output three-phase voltage of the frequency converter is balanced.

5、Motor overheating:

Check whether the load is too heavy, whether the inverter output three-phase power supply is balanced, and whether the motor cooling fan is normal.

6、the motor does not run smoothly:

Check the mechanical equipment failure, inverter output three-phase power supply is balanced, and speed sensor mechanical connection is bad.

7、the reason for the action of the protection function:

Overcurrent tripping may be caused by short acceleration time, overload or short circuit of the inverter output.

Heat sink overheating trip may be due to exhaust fan failure or heat sink ventilation channel blockage and other reasons.

8、maintenance:

Perform regular maintenance, inspection and overhaul of the motor to ensure that the motor operates within the recommended temperature range, and regularly check the cleanliness and operating status of the cooling system, heat sink and fan.

By following the above steps, you can effectively analyze and troubleshoot faults in the motor rotor slot paper machine to ensure stable operation of the equipment.
