hey, i've been looking EVERYwhere for equations for torque in a DC motor. i've come accorss plenty too:

T = µBsinθ
and T = k(magnetic flux per pole)I <- where k is a "mechanical and conversion constant" and I is the current in the armature, and i couldnt' find the magnetic flux symbol key thing.


now here's where im troubled...which is right? if ne of these are. and if it's teh second one...wut the hell is k supposed to be?

thanx for any help guys...itd be real awesome if someone had this knowledge tucked away in the back of their heads.
