YVFE4 IE4 VF Motor Assíncrono Trifásico
Engine description
Common faults and troubleshooting methods are as follows when this motor series fails during the operation process.
If the motor bearing is overheated, possible reasons are: 1) bearing failure; 2) improper grease filling in the bearing or poor quality; 3) asymmetrical coupling with the center or the pulley is not tight enough; 4) shaft and bearing are combined too loosely or too tightly; 5) the bearing is combined too tightly with the end cap; 6) the end caps or bearing caps at both ends of the motor are not mounted correctly. Relevant solutions are: 1) replace the bearing; 2) replace the grease with a filling capacity of 1/2~2/3; 3) calibrate the coupling or adjust the belt tension; 4) apply metallization if too loose and regrind if too tight; 5) insert steel bushing in the end cover if too loose and process the bearing chamber if too tight; 6) reassemble the motor.
If the motor shows excessive temperature or smoke during operation, the reasons could be: 1) overload; 2) high ambient temperature; 3) low supply voltage or connection error; 4) single-phase operation of the motor; 5) poor ventilation; 6) grounding of the stator coil or failure between turns, phase-to-phase; 7) broken busbar in the squirrel-cage rotor; 8) friction between stator and rotor. In this condition, the following solutions can be adopted: 1)
