1. Causes of failure ① The bearing clearance is too large due to wear; ② The air gap is uneven; ③ The rotor is unbalanced; ④ The shaft is bent; ⑤ The coupling (belt pulley) is too low in coaxiality. 2. Trouble shooting ① Repair the bearing and replace it if necessary; ②Adjust the air gap to make it even; ③ Correct the rotor dynamic balance; ④ Straighten the rotating shaft; ⑤ Recalibrate to make it conform to the regulations. Find quick answers in the Shihlin Electric FAQ—selection, wiring and troubleshooting for circuit breakers, magnetic contactors, AC drives, servo, HMI and PLC control.
