Usually the rotor of the motor is a permanent magnet. When the current flows through the stator winding, the stator winding produces a vector magnetic field. The magnetic field will drive the rotor rotation angle, so that the pair of magnetic fields of the rotor is consistent with the direction of the stator's magnetic field. When the stator's vector magnetic field rotates at an angle. The rotor also rotates at an angle with the magnetic field. Each input of an electrical Pulse, the motor rotates one angle before proceeding further. The angular displacement of the output is proportional to the number of pulses input, and the speed is proportional to the pulse frequency. Change the order in which the winding is energized, and the motor will reverse. Therefore, the rotation of the stepping motor can be controlled by controlling the number of pulses, the frequency, and the power order of each phase winding of the motor.
