Actual FP data from Johnson Electric

O.K. guys, here it is one last time. The attached spreadsheet is from the engineers at Johnson electric. Here are a few key points:

1. The 2002 FP motor is NOT the same as the previous years. It is made by Johnson Electric, while 2001 was made by Mabuchi.

2. The free speed of the Johnson electric motor is 20,326 RPM and
the Stall torque is 0.514 N-m at 12 volts. The stall amps are
109.4 and the free amps are 2.735.

3. The FP part number is 74290-9539 and is from the Harley Davidson Power Wheels vehicle. Use this number when ordering extra motors.

4. I have verified that the information given to me by Johnson Electric is correct.

Sandrag,

I looked on the web page you posted and the info is incorrect. The info on that web page shows the specs for the Mabuchi motor.
