A stepper motor has 8 stator teeth and 6 rotor teeth. Find the step angle.

Correct option is A

​$$\alpha = \dfrac{(N_s - N_r) \times 360}{(N_s \times N_r)}\text{where,} \\N_s = \text{Number of stator poles or stator teeth.} \\N_r = \text{Number of rotor poles or rotor teeth.}\text{Solution:} \\\alpha = \dfrac{(N_s - N_r) \times 360}{(N_s \times N_r)} \\= \dfrac{(8 - 6) \times 360}{(8 \times 6)} \\= 15^\circ$$​​
