Now as the industry develops and matures, rightMotorThe demand for the motor is increasing. For the motor, we need to master not only the operation, but the maintenance of the motor is also an indispensable mastering point.The motor is an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction.Frequency conversion speed motorA general term for motors driven by frequency converters.In fact, the motor designed for the frequency converter is a special frequency conversion motor. The motor can achieve different speeds and torques under the drive of the frequency converter to adapt to the changes in the demand of the load.Explosion-proof motorsA type of motor that can be used in flammable and explosive plants, and does not generate sparks during operation.Explosion-proof motors are mainly used in coal mines, oil and gas, petrochemical and chemical industries.In addition, it is also widely used in sectors such as textiles, metallurgy, city gas, transportation, grain and oil processing, papermaking, and medicine.The following small series is for you to check the motor maintenance and hope to help you use it in the future.Check once a day to see the working condition of the motor, the current size and changes, and see if there is leakage or dripping, which will cause low insulation breakdown and burnout of the motor.It also depends on whether the surrounding of the motor affects its ventilation and heat dissipation environment objects?Check if the fan cover, fan blades and the outside of the motor are dirty and need to be cleaned?Make sure it cools and radiates heat.

Second, listen: carefully listen to whether the abnormal sound of the motor is running, use a screwdriver or listening stick and other auxiliary tools to attach the two ends of the motor to listen. If you listen frequently, not only will you find bad vibration motors and dragging devices, you can even determine the bearings How much oil is inside, so increase the bearing oil in time, or use new bearings and other appropriate measures to deal with it, to avoid the short grinding stall of the oil dry motor bearing, take the outer circle, and sweep the combustion in the room.Third, touch: mold temperature and motor probe around the back.In good condition, the temperature of the bearing will usually be lower than the temperature at the two ends of the middle part of the winding.If it is at high temperature, test both ends of the bearing when used with the measured sound bearing bearing inspection as needed.If the overall temperature of the motor is high, it is necessary to check the load combined with the motor's operating current, ventilation equipment, etc., and the corresponding treatment.
