In one manufacturing workshop, a series of vibrating motor failures caused deep concern among the bosses. The cause of the incident involved the departure of two electricians and the inquiry of an ordinary worker into a similar problem in a friend's factory.
The key characters in this story are two electricians who were the pride of the workshop. But since they quit their jobs, there have been problems with the vibration motors in the workshop, and three motors have been scrapped one after another. The boss wondered why there were so many problems with the operation of the motors in the workshop after the electrician left.
During the workshop inspection, a worker walked up to me and asked me for advice with a troubled face. He told me that his friend's workshop had a similar motor problem, with three motors being scrapped in just a few days. His purpose was simple, to help his friend inquire about the cause of the problem, because he knew nothing about electricity.
The worker didn't know the power of the motor and didn't know how it was used, but he distinctly remembered that he was extremely confused by the frequent problems with the motors after the two electricians left. They don't know why the electrician left, and they don't want to ask too much, but the root of the problem must be identified.
I advised him to first inspect the contactor to see if the contacts were damaged, and if there was burning, to replace the contactor as soon as possible. Next, he needs to inspect the cables for possible breakage and aging, as well as for the connections from the switch to the contactor and the contactor to the motor. If there is a virtual connection problem, it needs to be fixed urgently.
In order to ensure normal motor operation, he should also check the switching voltage, ensure the matching between the switch and the motor, and recommend adding overheat protection or phase loss protection to the motor. However, considering the worker's own lack of experience as an electrician, I emphasize that it is best for him to find an electrician with relevant experience to deal with this problem to avoid potential risks.
The incident has also sparked speculation about the reasons for the electrician's departure. Perhaps because of the salary issue, the electrician was not satisfied with the salary and failed to meet his expectations. Or, the electrician may have a grievance against the factory or the owner. Whatever the reason, as technicians, we should uphold professional ethics and refrain from misconduct.
This story highlights the criticality of electrical equipment in manufacturing and the need to maintain it. The reliability of the motor is critical to the proper operation of the shop floor and the company. It is hoped that through inspection and maintenance, this workshop will be able to solve the motor problem, and also hope that the electrician can find a satisfactory job and meet his expectations.
