What causes vibration when using permanent magnet DC motors ?
First, check whether the three-phase voltage balances the first check and tighten the anchor bolts. Check the foundation for looseness (will not be loosened by the ground, ah). If the power test is invalid, go to the next step.
Second, release the load (belt, gear, etc.), permanent magnet DC motor, micro geared motor, permanent magnet permanent magnet DC motor, permanent magnet DC motor governor, micro motor power test to determine if it is caused by an unbalanced load, and if so , Adjust the load, parallel to the longitudinal direction of the DC motor shaft so that. If it doesn't work, the next step.
Third, the permanent magnet DC motor repairman checks the tightness of the screw cover, which is tied diagonally with or without sliding or without excessive screw holes. Scan it freely to check the phenomenon of the hole. If it blows up the chamber, recap and adjust the concentricity. If you cannot adjust it to the required level, then check, replace or repair the rotor in good condition. If it is invalid, go to the next step.
Fourth, check the integrity and replace the end cover bearings, permanent magnet DC motors, micro-reduction motors, permanent magnet DC motors, permanent magnet DC motors, and governor micromotors. If the bearings are in good condition, the gap between Tianjin Motors maintenance inspection bearings and coverage is Normally, if the gap is too large, it cannot be repaired or replaced. The next step if it doesn't work.
Fifth, check the stator winding resistance and insulation and restore it.
