in brushless dc motor controller bearing the reason of tight brushless dc motor controller by brushless motor controller of main body and brushless motor controller drives, compact structure, small volume, has the outer characteristic of dc motor without mechanical contact structure composed of brush. Affect the service life of brushless dc motor controller is bearing the main parts, brushless dc motor controller is cancelled carbon brush structure, so the whole of the brushless dc motor controller are main wear bearing parts. So if bearing failure, will be for the whole operation of the brushless dc motor controller have a big impact. So when bearing appeared what reason be? With everyone together to discuss the below. 1, because of the brushless dc motor controller with tight, bearing heating, have been pushed out to make grease, bearing the runway,Bearing face)There is no lubricating oil in the local, bearing bearing failures due to overheating. 2 worry lathe operators, there was a error in the bearing chamber caused higher rejection rate, brushless dc motor controller to make repair bearing outer ring and the end cover fit tolerance. Lay particular stress on the lower limit of the tolerance range, and not willing to limit, thus make the bearing chamber diameter smaller, increases the amount of interference with the bearing outer ring. 3, repairman to appropriately reduce the greater than the fit tolerance of surplus quantity of brushless dc motor controller of the understanding of the bearing to reduce noise is good enough, for example in the release bearing brushless dc gear motor controller may find bearing outer ring with end cover is very good, is mistaken for bearings with too loose. To adopt more or impaction of bearings, bearing in motor control operation will produce a bearing too tight. Brushless dc motor controller in addition to the above common cause of too tight, there's more unusual cause of tight brushless dc motor controller, in order to learn more about bearing problem in operation of the brushless dc motor controller, conditional when can do an inspection test before disassembly, avoid discovered bearing too close in time.
