Application Of Stepper Motor Subdivision Drive In Reducing The Starting Compression Degree Of Printer

With the rapid development and application of industrial automation technology, stepper motors, automated control system actuators, have been widely used in various industrial control equipment, especially in the industrial control machine tools, CNC machining, grinding processing and industrial cutting and other industrial automation equipment. Meanwhile, with the rapid development and application of high-precision CNC technology, as the main implementing agency for these devices, the control quality directly affects the entire device performance and relevant technologies.After nearly 50 years development, the structural design and materials of the stepper motor have reached the limit. To further improve the performance, we should improve its control accuracy with advanced stepper motor control technology. Subdivision control is used widely as a stepper motor control technology, which can further improve stepper resolution and stability of the motor due to its step angle stepping motor subdivided. However, there are still some deficiencies in the design and control algorithms. For the current subdivision stepper motor drive control, there are still a series of problems, such as unstable, uneven subdivision and subdivision algorithm difficult to require device controller, which greatly affects its overall promotion and application in the field of industrial control. On this basis, combining motor drive module of thermal printer products, an improved subdivision stepper motor drive control were studied. The driving performance of the stepping motor was analyzed from two aspects of subdivided driving design and subdivision optimization algorithm, and a trend adaptive subdivision stepper motor driver uniform optimization algorithm was presented. The theoretical model was researched and analyzed. Finally, the realization of this design flow chart of stepper motor driven electrical breakdown structures and associated algorithms were presented. The main work of this paper is as below:1) The current domestic and international developments in stepper motor and comprehensive, especially the fine for stepper motor minute drive technological developments were studied and analyzed.2) The stepper motor control theory and methods were analyzed, which was focused on the control principle and the Institute of Mathematical model. Two-phase hybrid stepper motor, stepper motor control for speed mathematical model analysis model, from acceleration and deceleration was studied. Then a uniform procedure was carried out for three mathematical modeling. The analysis of the advantages and disadvantages of various models is also present.3) The breakdown of the stepper motor drive technologies was also researched and analyzed. Driven by the principle of subdivision and subdivision control, mathematical model of drive-depth study for the application of subdivision stepper motor drive control were studied. The common segmentation method of driving and a comparative analysis of their strengths and weaknesses were described. The paper focuses on the current vector constant amplitude uniform subdivision driving method.4) The subdivision drive control technology, which achieves a stepper motor control model and completes hybrid stepper motor speed control function model design, was present. As for the hybrid segmentation drive stepper motor speed control function model design, we propose an adaptive optimization uniform arc approaching subdivision algorithm design. Finally a theoretical model based on the realization of the proposed algorithm was designed. This model gives a detailed algorithm flowchart and subdivision stepper motor electrical diagram and has carried out on the simulation and test verification.
