步进电机是一种将电脉冲讯号转换成角位移或直线往复位移的电磁装置,只要控制输入到电机中脉冲的数量、频率以及电机各相绕组的接通次序,便可获得所需的转角、转速和转动方向,从而带动有关执行元件(如丝杠)做相应的运动。由于步进电机具有一般电机所不具备的特性,所以在数控系 Stepper motor is a kind of electromagnetic pulse signal conversion into angular displacement or linear reciprocating displacement of the electromagnetic device, as long as the control input to the motor pulse number, frequency and motor phase winding turn-on sequence, you can get the desired corner , Speed ​​and direction of rotation, which led to the implementation of components (such as screw) to do the appropriate movement. As the stepper motor with a general motor does not have the characteristics, so in the Department of CNC
