hybrid stepper motor

The hybrid stepper motor consists of two parts: the stator and the rotor. The stator usually has 8 poles or 4 poles, with a certain number of small teeth evenly distributed on the pole surface, and the coil on the pole can be energized in two directions. The rotor consists of two tooth plates with a certain number of small teeth evenly distributed on the circumference. The two tooth plates are staggered by half a tooth pitch, and an axially magnetized annular permanent magnet is sandwiched in the middle.
