Four-Step Switching (Full Stepping)
The switching arrangement shown in Figure 35 – 6 can be used for a four-step sequence. 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 fifty 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°/200 steps = 1.8° per step.) Figure 35 – 7 illustrates the switch positions for each step.
