I can’t identify the DC motor with encoder from the current indexed file results.
What came back from search is only general workflow/reference material about handling attachments and parts, not the actual uploaded design content or a BOM entry for the motor .
If you want, send me one of these and I can help pinpoint it fast:
the motor’s designator in the schematic/BOM
the BOM/export file
the datasheet or product page
a screenshot of the relevant part of the design
If you upload or point me to the actual design file/BOM entry, I can tell you exactly which component it is.
