The step angle of a stepper motor is reduced by
Answer: A
Correct answer: increasing the number of rotor teeth or stator poles
\[ \theta = \frac{360}{\mathrm{steps\ per\ revolution}}, \] and the step count is fixed by the geometry - the number of rotor teeth and stator phases. Voltage, current and pulse frequency affect torque and speed but leave the step angle untouched; microstepping is the only electronic way to subdivide it.
