What is a step motor? What is the function and principle? thank you
Now more commonly used stepping motor including reactive stepper motor (VR), permanent magnet stepper motor (PM), hybrid stepping motor (HB) and single-phase stepper motor, etc.
Is convert electrical signal into mechanical angular displacement of a motor. It is controlled by the pulse signal, drives a pulse signal to it, it will turn a point of view, the size of the Angle, depending on the spindle and the number of teeth on the rotor, are generally of a point of view, so the stepper motor spindle and rotor tooth. There are dozens of displacement of the it transformation is very small. Usually is 0.01 MM or less. Principle is to change the power phase sequence rotation and inversion. Since the lock when it shut down.
Stepping motor is an actuator that converts electrical impulses into angular displacement. When stepping drive receives a pulse signal, it is driving a stepper motor according to set the direction of a fixed Angle (called "step Angle"), its rotation is based on the Angle of the fixed step by step. It can control the amount of angular displacement by controlling the number of pulses, so as to achieve accurate positioning. At the same time, the speed and acceleration of the motor can be controlled by controlling the pulse frequency to achieve the goal of speed adjustment. The step motor can be used as a control special motor, and it is widely applied to various open loop control, using the characteristics of not accumulated error (100% accuracy).
