Abstract
Steping motor was the key part of mechatronic technology production,it was a well used digitial Implementation components .this paper introduced the principle and Indicators data of Steping motor ,analysised the method of the Steping motor control based on Microcontroller
The system using the parallel communication control method between Microcontroller and Steping motor, as the Steping motor ’s controler ,the AT89C51 serial Microcontroer fulfill the motion control ,rsetion and such operation, the Steping motor’s operation signal was from the keyboard input signal.
The system Hardware structure was composed by the keyboard interface circuit, the electrical drive circuit, quartz multi-harmonic oscillation circuit. When the motor works, 12MHz quartz oscillator circuit multi-harmonic oscillation pulses generated by the opto isolators GTR control and turn-off of access to control stepper motors work .
Modular design of software through a series of subroutine calls, such as interruption, such as keyboard scanning stepper motor to achieve three-phase four-shot single, double and four single-shot, double shot of running eight. Gives the schematic diagram of hardware, programming flowc hart and some software programs.
