105.28 is the gear ratio.
The rated output speed is 12.348024316109422492401215805471 RPM, rounded or truncated to 12 RPM.
Is this important?
Did you realize that a 50 Hz induction motor rated for 1300 RPM will have 200 RPM slip?
That is the speed will vary from close to 1500 RPM at no load to 1300 RPM at full load.
The output speed will vary from 14.2477 RPM to 12.348 RPM at full load.
Many persons will happily accept a 5.28% rounding error.
