Stepping Motor application internationalization big trend.
Stepper motor rotor is usually permanent magnet, when the current flow through the stator winding, the stator winding produces a vector magnetic field. The magnetic field will drive the rotor rotation an angle, so that the rotor of a pair of magnetic fields in the same direction as the stator magnetic field direction. When the vector field of the stator is rotated at an angle. The rotor also rotates at an angle to the magnetic field. With each input of an electrical pulse, the motor rotates at an angle to advance one step. The angular displacement is proportional to the number of input pulses and the rotation speed is proportional to the pulse frequency. Change the order in which the windings are energized and the motor reverses. So can control the number of pulses, frequency and the power-on sequence of each phase winding of the motor to control the rotation of stepper motor.
