Answer: The motor operating environment should always be kept dry, the surface should be kept clean, and the air inlet should not be accumulated with dust, fibers and other debris. When the thermal protection and short-circuit protection of the motor are continuously activated, it should be checked whether the fault comes from the motor or the overload, or because the protection device is set too low. The motor can be put into operation only after the fault is cleared.
The motor bearing should be relubricated with grease after running for 1500~2000h. The maximum bearing temperature should not exceed . When the temperature is lower than , the interval time for relubricating grease can be appropriately extended. When filling oil, use a grease gun, first remove the oil plug on the oil drain pipe, add new grease until the original grease is discharged from the oil drain hole, wipe it clean with a rag, and tighten the oil plug after filling oil.
