Re: Torque on motors

Note that there's an error on that spec sheet regarding the Fisher-Price (Johnson) 9012. The peak power is usually the mechanical power output; for that motor only, they've instead substituted the electrical power input, when the motor is at full power. The maximum mechanical output is actually 171 W. (See here.)

Also, search ChiefDelphi for this stuff; it comes up frequently. (See here, for example; there's also a couple of equations for torque given there.) Just be sure to note the year of some of the threads, because the set of supplied motors frequently changes. For example, there are probably 7 different Fisher-Price RS-550 motors that have been in previous kits of parts—we don't know which ones (if any) will be legal next year.
