The 2-phase Hybrid Stepper Motor is a hybrid motor consisting of two parts: a stator and a rotor. The common stator has 8 poles or 4 poles with a certain number of small teeth evenly distributed on the pole surface; the coil on the pole can be energized in both directions. Its rotor is also composed of two pieces of teeth with a certain number of teeth evenly distributed on the circumference. The two pieces of teeth are staggered by half a tooth pitch from each other. Between the two teeth is an axially magnetized ring-shaped permanent magnet.
