What is the advantage of eight-step switching over four-step switching?
What will be an ideal response?
The advantage of this arrangement is that each step causes the motor to rotate one-eighth of a tooth instead of one-fourth of a tooth. The motor now requires 400 steps to produce one revolution, which produces an angular rotation of 0.9 degree per step. This results in better stepping resolution, and greater speed capability.
