Information

The service life of the three-phase asynchronous motor of the packaging machine is affected by the surrounding working environment, the gradual aging of the insulating material, and the gradual wear and tear of some components (such as bearings, commutators, and brushes). When used under normal conditions, the life of the motor of the packaging machine is relatively long. In order to avoid some undesirable phenomena in the process of using three-phase asynchronous motors, and to ensure the safe and reliable operation of the motors, the user must do the following five aspects.

(1) The rated power of the motor should be correctly selected according to the size of the load and the overload capacity of the motor.

(2) According to the characteristics and requirements of the load, correctly select the structure and rated speed of the motor. Generally, shunt-excited motors (hard mechanical characteristics) are required for mechanical equipment with constant speed, series-excited motors (soft characteristics) are required for transportation and hoisting equipment, and the motor's anti-vibration, wind, sand, rain and other erosion functions should also be considered. Motors used in mines must have explosion-proof and moisture-proof functions.

(3) Before using a new or repaired motor, carefully check whether there is any sundries inside the motor, and blow off the motor dust with dry compressed air. Use a 500 volt megohmmeter to measure the insulation resistance of the motor, and its value cannot be lower than 0.5 megohm. Rotate the shaft by hand to see if the rotation is flexible, whether there is cross movement or jamming.

(4) Check the position of the brush holder and whether the holder is firmly fixed, whether the brush pressure is appropriate, and whether the commutator surface is smooth and whether the brush is in close contact with the brush.

(5) After that, the three-phase asynchronous motor nameplate and circuit wiring diagram on the packaging machine should be connected correctly, and the motor should be energized and no-load operation. Observe whether the motor rotation direction is correct and whether there is any abnormal sound.
