Due to friction, vibration, insulation aging and other reasons,YEJBrake motor will inevitably fail, if timely inspection, find and eliminate these failures, can effectively prevent accidents. Here is a simple understanding with Senli Motor Xiaobian.
Listen to the sound and look for itYEJBrake motorThe fault point. If a finer "buzzing" sound is found, there is no high, low variation, which is a normal sound. If the sound is rough, the sharp "hum" and "hum" s"Sound is a harbinger of failure, and the following reasons should be considered:
Iron core loosens the motor(L)Vibrate during operation. Sudden changes in temperature will deform the core fixing bolts, resulting in loose silicon steel and large electromagnetic noise.
The "spinning" sound produced by the cooling fan, the sound of rotating rotation, is a "spinning" sound, just like the "spinning" sound of beating a drum. This is the motor suddenly start, stop, reverse braking and other variable speed, thus accelerating the rotation of the iron core and shaft. Lightweight equipment can continue to be used, and heavy equipment can be opened for inspection and repair.
YEJBrake motorDuring operation, the motor with bearing noise should pay attention to its sound, touch one end of the screwdriver to the bearing cover, and attach the other end to the ear, you can hear the sound changes inside the AC three-phase brake motor, different parts, different faults, and there are different sounds.
A motor that uses bromine sensing to analyze faults has no odor during normal operation. If you smell a bad smell, it will send a fault signal. For example, the burnt taste is generated by the insulation barbecue, and with the increase of the temperature of the AC brake motor, it will smoke in serious cases;For example, the smell of oil coke is mostly a lack of oil in bearings, and oil and gas will evaporate when it is close to drying.
Use the feel to check the fault, touch the TV shell with your hand, you can roughly determine the temperature rise. If you touch the motor housing with your hand, you feel very hot and the temperature value is very high. Check the cause, such as: the load is too high, the voltage is too high, and then troubleshoot the cause of the fault.
