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.
Stepper motor is a kind of induction motor, its working principle is to use electronic circuit, direct current into time-sharing power supply, multi-phase timing control current, with this current for the stepper motor power, the stepper motor can work normally, the driver is for the stepper motor time-sharing power supply, multi-phase timing controller.
