My expression is similar to the one you posted aolalde, however my expression does not contain the conductor average radius. Another thing I was considering is that I know that if I decrease the wire diameter, I will also decrease the torque. This really isn't taken into account in the above...
I am currently trying to design an armature for an electric motor. In trying to work out what my expected torque characteristics would be, I ran across an equation which calculates this value using flux, # of conductors, current, armature paths, and # of poles. I know the equation is correct...
