Today we are talking aboutThree-phase asynchronous motorCauses and elimination of problems such as sound and vibration frequency during operation:

       Note: If the motor fails, please be sure to be handled by technical personnel, strict non-technical personnel privately, otherwise it may cause personal and property losses.

       one. The running sound is abnormal,Abnormal sound
  
       1. Fault cause analysis  
       ①The rotor rubs against the stator insulation paper or the slot wedge
       ②Bearing wear or oil in the sand and other foreign matter
       ③The rotor core is loose
       ④Bearing oil shortage
       ⑤Air duct packing or fan hood
       ⑥Rotor core rub
       ⑦The power supply voltage is too high or unbalanced
       ⑧The stator windings are misconnected or short-circuited
 
       2. troubleshooting
       ①Trim the insulation and trim the wedge
       ②Replace bearings or clean bearings
       ③Check and repair the rotor core
       ④refuel
       ⑤Clean the air duct; remount
       ⑥Remove scratches inside small rotors if necessary
       ⑦Check and adjust the power supply voltage
       ⑧Remove stator winding fault. 

       two.In operation Three-phase asynchronous motorHigh vibration
 
       1. Fault cause analysis 
       ①Bearing clearance is too large due to wear
       ②The air gap is uneven
       ③Rotor unbalance
       ④Shaft bending
       ⑤The core is deformed or loose
       ⑥Coupling (pulley) center not calibrated
       ⑦Fan unbalance
       ⑧Insufficient housing or foundation strength
       ⑨The anchor screw of the motor is loose
       ⑩Cage rotor open welding break; The winding rotor is open; The stator winding is faulty.
 
       2. troubleshooting  
       ①Repair bearings and replace them if necessary
       ②Adjust the air gap to make it even
       ③Correct rotor dynamic balance
       ④Alignment of the rotating shaft
       ⑤Correcting overlapping core
       ⑥Recalibrate it to conform to the regulations
       ⑦Check the fan, correct the balance, and correct its geometry
       ⑧reinforce
       ⑨Tighten the anchor screws
       ⑩Repair the rotor winding; Repair the stator winding 

       Three-phase asynchronous motorRegular maintenance and overhaul is needed to avoid and reduce sudden damage accidents.
