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.


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.


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论文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。
