A stepper drive is changed from full step to half step. What is the result?

  1. The step angle is doubled, so half as many pulses are needed.
  2. The motor runs at twice the speed for the same pulse rate.
  3. The step angle is halved, so twice as many pulses are needed.
  4. The torque is doubled while the step angle stays the same.
Show answer

Correct answer: The step angle is halved, so twice as many pulses are needed.

Half stepping gives finer positioning and doubles the step pulses per revolution.
