O.K. everyone, I did a lot of researching on the new Fisher Price motor. 1st, the Mabuchi motor provided in the kit is LAST YEAR's Fisher Price motor, but Fisher Price has gone to a new supplier. The new supplier is Johnson Electric and those are the motors in our kit. They also supply the little 40 Watt motor. There are 3 numbers on the new FP motors: 64715 is Johnson's part number, 00801-0673 is FP's part number, and the 3rd number is a date code. I contacted Johnson Electric North America and talked to a gentleman named Chris Tsui. He e-mailed me the Performance curves for the 64715 motor. Attached is the EXCEL spreadsheet he e-mailed me. In sumary, the motor is roughly 20,000 RPM at free speed and has a stall torque of 0.514 N-m. It has a max mechanical power rating of 273 Watts. Stall current is 105 amps.

I have been talking with the FP service people and it looks like we will have to order these motors via special order. I will keep everyone posted. If anyone can get these motors easier, please let me know. At any rate, team 217 plans on special ordering 20 or so motors (~$20 each), so we will have spares to lend out at the events we attend.

Anyway, here is the spreadsheet.
