Re: Motor Quiz
I see, so stall torque also scales in the same way. A convenient way to can all this then would be with giving the speed vs. torque curve as speed/free speed + torque/stall torque = voltage/spec voltage.

For another shot then:
Spoiler for Let's try that again:
Free speed = 5310rpm
Stall torque = 2.43Nm
Spec voltage = 12V

Speed = 3700rpm
Load = 60oz-in = 0.42 Nm

So voltage = 12 * (3700/5310 + 0.42/2.43) =

10.43V
