Motor Manufacturer? / Motor SLDPRT seem corrupted

[GerOTEC]

Hello! / 您好!
I work for a company in Germany, where I lead the development of a new prototype.

I recently bought an Ender 3 and was astonished by the precision of the motors, so we wanted to try some of them out for a new prototype (no 3D Printer, it's a measuring-device with an XYZ-table).
Unfortunately, I can't find the motors anywhere on the Internet, nor the manufacturer.

Also, the files for the motors seem corrupted, it doesn't work for me on various programs.

Is it possible to get this Information? Would be very happy about it!

谢谢 and greetings from Germany,
Jan
