在生产过程中要求自动化，省人力，效率高的机器中，我们很容易发现步进电机的踪迹，尤其以重视速度，位置控制，需要精确操作各项指令动作的灵活性控制场合步进电机用的最多。另一方面，微型计算机和数字控制技术的发展，又将作为数控系统执行部件的步进电动机推广应用到其他领域，如电加工机床、小功率机械加工机床、测量仪器、光学和医疗仪器以及包装机械等。

Requirements of automation in the production process , save manpower , high efficiency of the machine , we can easily find traces of the stepper motor , particularly in the emphasis on speed and position control, the directive requires precise operational flexibility of movement with stepper motor control applications most. On the other hand , micro- computers and digital control technology , in turn CNC system to perform as part of a stepping motor extended to other areas such as electric machines , machining small power tools, measuring instruments, optical and medical instruments and packaging machinery.

步进电动机多用于数控车床和机器人系统中．在现代工业，特别是航空、航天、电子等领域中，要求完成的工作量大，任务复杂，精度高，利用人工操作不仅劳动强度大，生产效率低，且难以达到所要求的精度，还有一些工作环境是对人体健康有害的或人类无法到达的，这就需要数控机床和机器人来完成这些工作．

Stepper motors for CNC lathes and multi- robot system . In modern industry , especially in aviation, aerospace, electronics and other fields , the large amount of work required to complete the task complexity , high precision, using the manual operation is not only labor-intensive, low productivity, and it is difficult to achieve the required accuracy , as well as Some work environments are harmful to human health or human can not reach , which requires CNC machine tools and robots to accomplish these tasks. In addition, computer peripherals and office automation equipment also make extensive use of stepper motors, such as disk drives , printers , plotters and copiers.

步进电机技术，历经上世纪几十年的发展，已成为相对成熟的技术．但随着应用范围的推广和新工艺、新技术的不断出现，步进电机技术仍然在不断发展完善中．主要表现在步进电机本身的改进以及驱动技术的多样化和精密化等几个方面．

Stepper motor technology , after decades of the last century of development, has become a relatively mature technology . But with the promotion and application of new techniques, new technologies continue to emerge , stepper motor technology is still evolving perfected. Mainly in the improvement of the stepper motor and drive technology itself diverse and sophisticated technology and other aspects.

Currently, the most promising undoubtedly hybrid stepping motors, and hybrid motor ED also the following four directions: miniaturization direction. With the motor itself and a variety of application areas to broaden the continuous miniaturization machine , requiring ancillary motor must also be getting smaller and smaller , in 57,42 frame size motor applications for many years now after its frame size extending downward to 39,35,30,25 .

Switzerland ESCAP has also recently developed a diameter of only 10mm stepper motors. Change a square round motor motors. Since the motor using rectangular structure, making it possible to design the rotor than large round , and thus its volume ratio of torque will be greatly improved. The same frame size of the motor torque than the circular square will increase by 30 % to 40% . Integrated design. That is, the rotor position sensor , gear reducer and motor body integrated design together, so that it can easily form a closed loop system , which has more superior control performance. To the five -phase and three-phase motor direction. The widely used two -phase and four -phase motor, rotating magnetic field and the electromagnetic torque is not completely symmetrical , vibration and noise is large, while the f
