Level 1 China stepper motor supplier The stator windings produce a vector magnetic field when the current flows through them.The magnetic field will rotate the rotor by an Angle, so that the direction of the pair of magnetic fields of the rotor is consistent with the direction of the stator magnetic field.When the stator's vector magnetic field rotates by an Angle.The rotor also rotates an Angle with the magnetic field.For each input pulse, the motor rotates an Angle forward.The output angular displacement is proportional to the input pulse number and the speed is proportional to the pulse frequency.If you change the order in which the windings are energized, the motor will reverse.Therefore, the number and frequency of pulses and the current sequence of each phase winding of the motor can be controlled to control the rotation of the stepping motor.
Stepping motor is an open-loop control element that converts electric pulse signal into angular displacement or linear displacement.In the case of the overload, motor speed, stop position depends only on the pulse signal frequency and pulse number, and not affected by load change, when the stepper driver receives a pulse signal, it is driving a stepper motor according to set the direction of a fixed point of view, called "step Angle", its rotation is based on the Angle of the fixed step by step.The angular displacement can be controlled by controlling the number of pulses so as to achieve the purpose of accurate positioning.At the same time, the motor speed and acceleration can be controlled by controlling the pulse frequency, so as to achieve the purpose of speed regulation.
