CIM Motor Failure

[Ether]

...we didn't get to do any post-mortem on the motor because we swapped it at spare parts desk during one of our regionals for a fresh one. It would have been nice to know FOR SURE that the motor was the root cause, or to know what exactly with the motor was the root cause, however in the heat of competition, this was not a priority

What does the spare parts desk normally do with a CIM motor in that situation? Do they throw it away, or do they set it aside somewhere?
