Electric motors are widely used in industrial production and our daily lives, from large-scale equipment in factories to household appliances like fans and refrigerators. Due to their frequent use, motors are prone to various malfunctions, which can result in significant economic losses for businesses, and even pose risks to human lives. Understanding the causes of motor failures is crucial for fundamental prevention.
Firstly, the use of motors requires an appropriate environment, and it is best to avoid operation in high humidity conditions. Excessive surrounding temperatures can prevent the motor from achieving thermal equilibrium, making it prone to burnout. In production environments with high humidity, extra caution should be exercised to prevent water vapor, liquids, and other substances from contacting the motor, as this can damage the motor's insulation.
Secondly, there are strict requirements for power voltage during motor operation. Voltage fluctuations, such as being too high or too low, or unbalanced three-phase power, can render the motor inoperable. Operating the motor under unsuitable voltage for extended periods can lead to motor damage. Additionally, the motor must not be overloaded. Operators must adhere to standard operating procedures, as prolonged overloading is a primary cause of motor failure.
Thirdly, during prolonged use, various connecting parts of the motor will experience corresponding wear. Excessive noise from the motor's operation is primarily due to friction caused by insufficient lubrication in the motor bearings. Therefore, regular lubrication should be added during routine motor maintenance to reduce wear and tear caused by bearing friction.
In summary, proper operation and regular maintenance are crucial for the motor's optimal use. Additionally, selecting a motor of reliable quality is essential, as it provides greater assurance for our production.
