Reaction: The stator has windings, the rotor is composed of soft magnetic materials. The structure is simple, the cost is low, the step distance angle is small, can reach 1.2°, but the dynamic performance is poor, the efficiency is low, the heat is big, the reliability is difficult to guarantee. Permanent magnet Type: Permanent magnet type of the rotor of the stepper motor is made of permanent magnet material, and the number of poles of the rotor is the same as that of the stator. Its characteristic is that the dynamic performance is good, the output torque is big, but this kind of motor precision is poor, the step moment angle is big (generally is 7.5° or 15°).
