步进电机是一种将电的脉冲信号转换成相应的角位移(或线位移)的机电元件,在数字控制系统中有广泛的用途。在一般的数字控制系统中,对于步进电机的控制是通过下述各环节实施的:第一、步进电机需要有环形分配器把脉冲信号按一定的规律,顺次加给它的各绕组,随着步进电机及其运行方式的不同(如三相六拍,四相八拍,五相十拍等),环形分配器也要作相应的改动。第二、为了提高步进电机的运行频率,保证在起动和突停时不发生丢步现象,必须有自动升降速线路,以克服由于步进电机的起动频率所带来的局限性。第三、步进电机作为进给传动系统中的执行元
Stepper motor is a kind of electromechanical pulse signal is converted to the corresponding angular displacement (or line displacement) of the electromechanical components, digital control system has a wide range of uses. In the general digital control system, the control of the stepper motor is implemented through the following steps: First, the stepper motor needs a ring-shaped divider to apply the pulse signal to each of its windings in sequence according to a certain rule , With the stepper motor and the different modes of operation (such as three-phase six-beat, four-phase eight-beat, five-phase ten shots, etc.), the annular distributor also make the appropriate changes. Second, in order to improve the operating frequency of the stepper motor, to ensure that the start-up and sudden stop does not occur when the phenomenon of lost, automatic speed-raising lines must be in order to overcome the limitations due to the stepping motor starting frequency. Third, the stepper motor as the feed transmission system in the implementation of yuan
