How Much RPM Does a 5.5 Watt Motor Have?

On the paper it says 120 rpm, but on “devices” it is 200rpm.

On which “paper” ?
The 5.5W motor is nominally a 200rpm motor.

I’m pretty sure it is 200 rpm. A full motor with a blue cartridge is 600 rpm (6:1), a green motor cartridge is 200 rpm (18:1), and a red motor cartridge is 100 rpm (36:1).
