Give an overview of four-step switching.
What will be an ideal response?
Each time one of the switches changes position, the rotor will advance one-fourth of a tooth. After four steps, the rotor has turned the angular rotation of one "full" tooth. If the rotor and stator have 50 teeth, it will require 200 steps for the motor to rotate one full revolution. This corresponds to an angular rotation of 1.8 degree per step. (360 degrees/200 steps = 1.8 degree per step.)
