Torque in DC Machines Formulas

Torque is the measure of the turning force produced by the armature. It is produced by the interaction between the magnetic field of the stator and the current flowing through armature. And is denoted by τ. Torque is usually measured using the Newton Meter for Torque. Note that the value of Torque is always negative.
