Machining of pin holes
Thread Content
The motor bearing base has moved a little, and the pin hole is slightly out of alignment; how can it be processed so that the pin can be inserted? What tool to use? Thank you!
This pin is used for installing the positioning pin; it must not be moved under any circumstances. Adjust it by the appropriate amount, especially regarding the positioning of the motor bearings; this is related to many factors such as the alignment of the rotor from a mechanical perspective and its levelness ； Changes in the magnetic center line in electrical aspects, etc. Under no circumstances should it be moved; if movement is necessary, it must first be tested and certified by the motor manufacturer before it can be used again.
Drill the hole with a reamer and reinstall the pin
