To explain the variation of torque and the principle behind the rotation of the motor let us do a stepwise analysis. Step 1: Initially considering the armature is in its starting point or reference position where the angle α = 0. Since, α = 0, the term cos α = 1, or the maximum value, hence torque at this position is maximum given by τ = BILw.
