传统电动机作为机电能量转换装置，在人类的生产和生活进入电气化过程中起着关键的作用。可是在人类社会进入自动化时代的今天，传统电动机的功能已不能满足工厂自动化和办公自动化等各种运动控制系统的要求。为适应这些要求，发展了一系列新的具备控制功能的电动机系统，其中较有自己特点，且应用十分广泛的一类便是步进电动机。

Conventional motor as electromechanical energy conversion device, the production of human life into the electrification process plays a key role. But in human society entered the era of automation today, the traditional function of the motor can not meet factory automation and office automation and other motion control systems. To meet these requirements , the development of a new series with the motor system control functions , which are more their own characteristics, and the application is very broad class of stepper motors.

步进电机作为控制执行元件，是机电一体化的关键产品之一，广泛应用在各种自动化控制系统和精密机械等领域，随着微电子和计算机技术的发展，步进电机的需求量与日俱增，在各个国民经济领域都有应用，现在比较常用的步进电机包括反应式步进电机，永磁式步进电机，混合式步进电机和单相式步进电机等。

Stepper motor as the control actuator is a key mechatronics products, widely used in a variety of automated control systems and precision machinery and other fields, with the development of microelectronics and computer technology , increasing demand stepper motor , have applications in various areas of the national economy , now more commonly used stepper motors include reactive stepper motors, permanent magnet stepper motors, hybrid stepper motors and single-phase stepper motors. Wherein the reaction stepping motor rotor magnetic circuits made of a soft magnetic material , multi-phase exciting winding on the stator , the use of magnetic torque generated by changes in conductivity . At this stage, the reaction stepping motor to get the most applications . Stepper motors and general motor is a stepper motor differs from a control pulse signal received , it is this characteristic, the stepping motor can be controlled and modern digital technologies.

  Stepper motor first developed by the British in 1920 , in the late 1950s invention of the transistor is gradually applied to the stepper motor. Stepper motor development and computer industry and digital control technology is closely related to the product structure is divided by a reluctance , permanent magnet and hybrid and other forms. In recent years , along with the microelectronics power electronic devices and drive technology, developed countries have widespread use of superior performance hybrid stepper motors , the most typical product is the two -phase 8-pole 50 teeth motor step angle 1.8 ° / 0.9 ° ( full / Half Step ) ; another five -phase 10-pole 50 and a number of rotor teeth 100 teeth two -phase and five -phase stepper motor , five -phase motor is mainly used for running high performance applications. Drive technology and segmentation using constant phase current drive combine to make the stepper motor in medium and small power control system to improve the accuracy and speed gradually to penetrate high-power applications . Stepper motor is the largest producer in Japan , such as Japan servo , Orient Corporation , SANYO DENKI and MINEBEA and NPM companies , especially in Japan Eastern Company , both motor performance and appearance quality or means of production , are the best in the world the .

Study of the stepper motor since 1958 , before the 1970s under Soviet influence , three-phase reluctance stepping motor based, such as the late 1960s as a fast wire NC WEDM developed BF1840-75, has been continued production until now. 1970 by domestic development an本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
