Max velocity of different smart motor cartridges

There are three types of cartridges: blue, green and red with different gear ratios. The max velocity for the green one is 200 RPM. Based on the gear ratio the maximum velocity for the blue one should be 600 RPM, but the maximum speed of the blue cartridge can only reach 380 RPM. Any idea why? Thanks

This is an ideal maximum, if you have something like a drive slowing it down, you might not be able to hit the 600 rpm.


What he said. Also, if you check motor watts, Iā€™d bet they are maxxed out @ 11 watts.
