fischer price motors
 

does anybody have the specs for the fishcer price motors or know where i can get them. specifically the amount of current they draw.

White Papers......
 

You might want to look under the White Papers for something on motors....


maybe the "FIRST Motors, Etc. (spreadsheet)" on the first page could help....

Going From Memory...
 

From my memory, I think the stall current is somthing like 60 Amps. The free speed is 15K RPM. The stall torque is .3 N-m.

The spread sheet will have the true numbers, but the above numbers are prettty close.

Fisher-Price motor spec...
 

From the 2001 FIRST Robotics competition Manual, Robot Appendix: H Part specifications...

Can be found at http://www.usfirst.org/2001comp/Docs/
"The Robot - Part 4"

"Fisher-Price motor information

The following are approximate performance data for the Fisher-Price motor/gearbox sets supplied in the kits. The motor used is a Mabuchi model RS-550PF-6534.

Motor no-load speed 15,000 RPM
Motor stall current 57 A
Motor stall torque 0.363 N-m
Gearbox ratio 147:1
No-load speed w/gearbox 100 RPM (estimated)
Stall torque w/gearbox 34.7 N-m (estimated)"

The fourth sheet has data for all the motors. The first three let you input the data about a specific motor and get plots for the power, efficiency, speed, etc with respect to torque.
