Fisher Price Motor:
Stall Torque: .36 N-m … 3.186 lbs per square inch
Stall Current: 57 A
RPM: 15,000
Peak Power: 140 W
now it says that the rpm is 15,000... dont forget that if you take the gearbox off the fisher price has 60,000 rpm.

Arefin and all...
These are
not the motor specs for the F-P motor for this year's robot. It is currently being investigated and an answer will be posted early this coming week.
If I were a betting man (which I am), I would guess these numbers:
*** ALERT - This is just a guess!! ***
free speed: 15,000 rpm
peak power: 260 Watts
Stall torque: .67 N-m
Here is some history:
2001 F-P motor: Mabuchi w/ 150 watts and 15,000 rpm free speed
2002 F-P motor: Johnson w/ 270 watts and 20,000 rpm free speed
2003 F-P motor: Mabuchi w/ 150 watts and 15,000 rpm free speed
Here are two facts for the 2004 F-P motor:
It is a Johnson.
It has a free speed of 15,000.
I am guessing that it has the same power of the 2002 motor (or similar), but wound differently so it has a lower free speed. I'm an optimist, so this guess is really a "hope".
I usually don't like posting numbers that I am not sure of, but I did want to make sure that there is much uncertainty here with this motor.
