摘要:本文主要以单片机为主控制器提出了整个系统的硬件设计方案,并以“光电自动检测系统”为背景,设计微型步进电机控制电路,用单片机C语言和串口通信实现电路控制步进电机的正常运转。

随着网络技术的深入发展,对步进电机的研究也逐步从单机运行转向网络化控制.如我国数控加工设备,目前大多数仍处于单机运行方式,采用手工或微机辅助分段输入、分段加工的方法,设备利用率普遍较低.

With the further development of network technology , the stepper motor research has gradually shifted from a stand-alone network control . Such as our CNC machining equipment , most still in the stand-alone operation mode , using manual or computer-aided segmentation input , segmented processing methods, equipment utilization is generally low . Small quantities in a variety of conditions, the cutting tool only 25% of the time , if the variety of CNC machining equipment through the bus network, constitute DNC (Distributed Numerical Control: distributed CNC ) system , the machine can reach 65% of the cutting time , and easy to implement integrated control and management , is a stepper motor promising direction of development .


步进电动机经过几十年的发展,已成为除直流电动机和交流电动机以外的应用最广泛的第三类电动机.在开环高分辨率的定位系统中,至今还没有发现更合适取代它的产品,特别是在一些功率相当小的系统中,步进电机更具有无可替代的主流地位.预计未来步进电机的研究还会持续深入下去,研究方向之一是电机与驱动的一体化,使步进电机体积更小巧、性能更优越,性价比更高,在大量的民用设备中批量化使用,如家庭机器人、民用智能化设备等。

Stepper motor after decades of development , has become an addition to DC motors and AC motors other than the most widely used third- class motors. In the open- loop high-resolution positioning system , has yet to find a more suitable product to replace it , especially in relatively small power system , the stepping motor more mainstream irreplaceable . Future research is expected to continue for the stepper motor to go in depth , research direction is the integration of motor and drive , the stepper motor more compact size , better performance, more cost-effective in a large number of civilian equipment used in batch such as home robots, equipment and other civilian intelligence ; research directions of the two is in power, or a relatively large frame size stepper motor, and belonging BIDCM ( rare earth permanent magnet brushless DC motor ) AC servo motor system rendezvous, Specifically may draw AC servo system control technology, but retains some of the characteristics of stepper motor , the formation of a new " stepping servo motor " or " servo stepper motors ," in overcoming the low frequency oscillation , high frequency overload capacity is small , fast and low efficiency of lack of breakthroughs , resulting in the modern military , precision machining , aerospace and other fields more and more deeply .

This paper presents a microcontroller -based controller hardware design of the entire system , and to " automatic photoelectric detection system " as the background, design micro stepper motor control circuit , MCU Serial Communication C language and stepper motor control circuit normally.

Maximum load starting frequency : motor drive in some form , voltage and rated current without load in the case of the maximum frequency can directly start . Maximum load operating frequency : motor drive in some form , voltage and rated current, the motor without load maximum operating frequency .

Motor torque characteristics : the motor in a test run under the conditions measured with pulse frequency output torque curve is called the relationship between the motor torque characteristics , which is a lot of dynamic curve of the motor is the most important , but also the fundamental basis for the motor selection . The motor torque at low speed near the static torque , as the motor speed increases, th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。
