Description
Fanuc CNC motor maintenance
Model: A06B-0141-P342
Failure phenomenon: jitter
Failure analysis: the customer response to the start jitter noise, eliminate the driver and the fault phase. That might be the direct internal components of motor commutator or tachometer to lead off the centrifugal force imbalance jitter. Remove the rear detection tachometer has obvious fault traces of burnt, gun replaced after re cleaning internal installed after all normal test. In the brush maintenance Note: brush the use of good performance marks should be: A in the commutator or slip ring surface can rapidly form oxide film and a layer of uniform, moderate and stable. B brush has long service life, do not wear commutator or slip ring brush C has good reversing and collecting performance, the spark suppression in the allowed range, and low energy loss. D brush running, not overheating, noise is small, reliable assembly, not damaged.
1 brush into the brush holder to be able to move up and down freely, brush and brush the gap between the inner wall of the 0.1-0.3 mm, in order to avoid the brush and brush grip due to the gap between too large to swing. Brush under the edge of the distance from the commutator surface should be maintained at about 2 mm. If the distance is too small, easy to brush touched the commutator, the distance is too large, easy to brush fibrillation and lead to breakage.
2 in the same motor, in principle, should use the same type of brush, but for large and medium-sized motor reversing the individual particularly difficult, can use the brush to slide into the side of Gemini, with good lubricating property, slide out the edges of the brush spark restrain ability, so as to make the operation of improved brush.
3 brush wear to a certain degree to the replacement of the brush, brush the best time to replace them all, if the old and new mix, may appear the phenomenon of uneven distribution of current. For large units, replacement of the brush, is bound to affect the production, you can choose not to stop, we usually recommend that clients is 20% brush each replacement (i.e. each brush rod per motor 20%), each time interval of 1-2 weeks, and then gradually changed to be run in the rest of the electric brush, the normal continuous operation of the unit the.
Including FANUC servo motor maintenance: can not start, start to run, jitter, loss, overcurrent, overload, Paowei, output imbalance, encoder alarm, encoder and damage location not a power on a power trip alarm magnet steel explosion death card can‘t turn the encoder motor wear heat hot maintenance of electrical abnormal operation maintenance Hong Jia Wei can repair.
