"Why is disassembling a servo motor a bad idea?"
A true horror story with a happy ending.
This customer, based in Florida, was machine down, so their maintenance department went ahead and disassembled the motor.
BUT, servo motors have internal feedback devices and their alignment angles are critically important for proper control interfacing (the servo motor and it's servo controller have to be in sync).
The customer swapped the bearings, but then found that they did not have the necessary equipment nor knowledge to reset the alignment.
A bad problem had just become worse.
They rushed the motor to us. We fortunately had the factory alignment data on file; we completed the repairs; the customer flew to North Carolina and hand carried the motor back to their plant. Success!
The morale of the story: don't start turning bolts on a servo motor, or you will lose the alignment data.
Leave these repairs to the experts.
