nForce:
How do we get "K" in this circuit? Is the calculation correct?

Thanks.

awallin:
didn't your teacher teach you to use units after each number?  ;D

it would also help if you'd specify the unit you want for "K"

nForce:
I think here we don't have any units. K is just a constant to get from ADC to the motor.

Benta:
Calculation looks OK. Unit is RPM/bit.

Ok Benta, if you understand, can you explain how do I get "K" and some comments about derivation?
