How long is the typical service life of a motor?
Thread Content
Recently, when investigating the cause of a motor burnout, many possible reasons were identified; one of them seems a bit unclear to me: the vast majority of these motors have been in operation for 10 years, are now in a period with a high incidence of failures, and also have relatively high energy consumption. I would like to ask those in the electrical engineering field: after how long of use does a motor generally need to be considered for replacement? Because if there are issues such as \"peak periods of failures\" and increasing energy consumption year by year, wouldn’t it be better to consider an upgrade?
Those whose energy consumption does not meet the standards must be replaced compulsorily
So I’d like to know how to determine whether a motor needs to be replaced. Many large motors can operate properly, while those with a capacity of less than several dozen kilowatts tend to have more problems
Domestic motors with a power rating of less than several dozen kilowatts are not expensive. In my opinion, they can be replaced gradually after more than 10 years; this is especially true for single-phase motors. On one hand, this is necessary to meet energy consumption requirements. If there are frequent inter-turn short circuits or ground faults, it indicates that the insulation level between the coils has declined significantly. Insulation can be tested regularly, and replacement strategies can be formulated based on the trends in historical data
With proper maintenance of the motor and satisfactory manufacturing quality, it can operate for thirty to forty years without any problems. As long as its energy consumption meets the **standards**, there are no issues such as frequent failures or mandatory retirement. Strengthening inspections and maintenance, such as regular refueling, timely repairs and tests, can break the so-called cycle of high failure rates.
It’s that there are doubts about that conclusion. Of course, with rapid technological progress these days, it’s possible to doubt situations where obsolescence results from technical improvements, as well as cases caused by inherent manufacturing issues
The company’s accounting system applies depreciation rates to assets; it depends on the depreciation period
I also think we should follow the depreciation schedule and replace the equipment once its depreciation period is over, so that all production facilities remain new and don’t give the impression of being an old company;P
When choosing a motor, it depends on the brand. Motors with high energy consumption must definitely be phased out over time according to set deadlines
