**FIRST EMAIL**/Fisher-Price Motor Information

Hello. This is an important announcement for all FIRST Robotics Competition teams. Please share this information with the rest of your team in a timely manner. If you think that other members of your team would also like to receive these announcements, please encourage them to sign up at http://listserv.leapit.com/cgi-bin/l...join=frcpublic.

If you would like to stop receiving these messages, please see the bottom of this message for instructions.

Greeting Teams:

Caution is advised regarding the Fisher-Price motor. Because of the apparent short supply of Fisher-Price motors (made by Mabuchi), FIRST advises that teams try very hard to protect the Fisher-Price motor from being burned up or fried.

FIRST advises that:
You consult the torque curve for the motor and do not operate beyond the peak power point
You not "stall" the motor, which will subject the motor to very high current
You limit the voltage to the motor (via programming) to 6V
You use a 20A Snap Action breaker
We do not guarantee that this will protect your motor from damage, but it may help you.

FIRST is working hard on replacement motors. More information to follow soon.

Go Teams!
