Two phase hybrid stepper motor is a type of hybrid motor. The two-phase hybrid stepper motor consists of a stator and a rotor.

The common stator has 8 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 two directions. Its rotor is also composed of two pieces of teeth with a certain number of small teeth evenly distributed on the circumference. These two teeth are offset by half a tooth pitch from each other. There is an axially magnetized annular permanent magnet sandwiched between two teeth. Obviously, all teeth on the same rotor blade have the same polarity, while the polarity of two different rotor blades is opposite.
