Correct Answer - Option 3 : 1.8°
Concept:
Step angle of the hybrid stepper motor is given by
\(β = {{(N_s -N_r)× 360°} \over (N_s× N_r)}\)
Where Ns = Number of stator teeth
Nr = Number of rotor teeth
Calculation:
Given that, Nr = 50
Ns = 40
∴ stepping angle can be calculated as
\(β = {{(50 -40)× 360°} \over (50× 40)}\)
β = 1.8°
