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)
