Question

The step angle of a stepper motor is given by

• A. \( \frac{180^\circ}{\text{No. of stator phases} \times \text{No. of rotor teeth}} \)
• B. \( \frac{360^\circ}{\text{No. of stator phases} \times \text{No. of rotor teeth}} \)
• C. \( \frac{360^\circ}{\text{No. of stator teeth} \times \text{No. of rotor teeth}} \)
• D. \( \frac{180^\circ}{\text{No. of stator teeth} \times \text{No. of rotor teeth}} \)

Hint:

Smaller step angles give finer resolution in stepper motors.

Answer 1

The Correct Option is B

Step angle \( \theta = \frac{360^\circ}{\text{No. of stator phases} \times \text{No. of rotor teeth}} \)
