Re: Testing Motor for Specs?

Can I use one of the charged batteries for a FIRST robot to provide the power source or am I looking at a dangerous situation?

No do not use a twelve volt battery as a power sorce for a toy car motor. I doubt that your toy car motor is designed to use twelve volts. There are a bunch of solutions that I can think of for your problem:
You should be able to dervie the voltage constant/voltage ratings using these methods:
1)Find the toy car and find out what voltage batteries it used.
2)If you have acess to a power supply apply two differnt voltages to the motor and then find rpms's. Dervie data using voltage equations.
3)If you have acess to variable drill press clamp the motor's shaft to the drill press and spin it at two differnt speeds. Find voltages at each speed. Derive data using motor equations. If you want to know what these equations are there are a bunch of equations from which you can dervie those neat little graphs that first gives us every year. I would recommend you pick up building sumo robots, building combat robots, or I believe building robot drivetrains might have the equations.
