No motor manufacturer can conduct type tests on all three-phase asynchronous motors produced. Instead, they can conduct quantitative or qualitative appraisal of some performance indicators of three-phase asynchronous motors through the essentials of inspection tests. Hubei Wanbang Motor Factory reminds that special It is the motor temperature rise index, which mainly depends on the type of technology and quality control methods to achieve the consistency control requirements of the motor performance index.

　　If the quality of the three-phase asynchronous motor meets the requirements, if it is used improperly, it will also cause the winding of the three-phase asynchronous motor to have a fever. In severe cases, the motor winding will be burnt.

　　Low voltage operation causes a fever in the windings.It is mainly produced in some environments with poor power supply conditions, such as motors that are temporarily used outdoors. In view of the fact that the motor use point is far from the power supply location, the power supply capacity is insufficient, the power supply line chooses inferior cables with low cost but high resistance, which is caused by cities. The voltage entering the motor is insufficient, which will naturally cause the motor to have a fever.

　　●The operation of the motor counteracts the influence of the ventilation system.For some equipment, due to the scope of the motor installation space, the ventilation and cooling system of the motor may be affected. The problem is even more serious if the motor fan and wind cover are damaged and used without repair.Therefore, to deal with motors with such problems, the temperature rise margin of the motor should be fully considered, and the factors affecting the heat dissipation of the motor should be eliminated and eliminated to ensure the safety of the motor operation.

　　●The matching relationship between the frequency conversion motor and the cooling fan and the running process.For the frequency conversion motor that recovers independent fans, it is a fundamental principle that the two cannot share power, and the requirement that the fans start and then shut down should be recovered to ensure the heat dissipation requirements of the motor running process, and for some practical applications, fans will probably appear An environment where only the motor is running without operation will inevitably lead to a fever problem in the motor windings.

　　●The motor is overloaded or started frequently.Any motor has its rated power. If the motor is permanently overloaded or starts frequently, the city will cause a fever in the motor windings.

　　In short, the reliability of the motor manufacturer's control of the quality of the motor not only requires the establishment of a type of manufacturing process regulation, but also the basic conditions for guaranteeing the normal operation of the motor during the utilization process.

　　Hubei Wanbang Motor Factory, a manufacturer of three-phase asynchronous motors for 28 years, has several motor assembly lines, which meets the requirements of small batches and multiple varieties of customers.
