We are running a 50:1 and we have taken it apart. The problem almost surely lies in the key skipping because when we opened things up there was a mark on the shaft of the CIM all the way around that was likely made by the key spinning round and round.

Also the main issue is the free spinning of the motor which is related to the connection between the shaft of the CIM and the collar from the gearbox. We are trying to figure out a better way to connect the two than the set screw and key options that we have already played with.

I will say that the key held up for a solid amount of testing and practice before giving way.
