ABSTRACT: A stepp ing motor control system based on AT89C52 chip microcomputer was described.The data can be inputwith keyboard, and stepp ingmotorwas controlled by these data. According to the demand, users can set the workingmodel of stepp ingmotor in real2time. This system can be widely used in stepp ing motor controlling. The p ractice showed that the performance of this system outdid the tradi-tional stepp ing motor controller.
基于單片機(jī)的步進(jìn)電機(jī)開環(huán)控制系統(tǒng):通過ATMEL89C51單片機(jī)對步進(jìn)電機(jī)進(jìn)行控制,主要介紹了步進(jìn)電機(jī)控制器、驅(qū)動電路和LED顯示電路的設(shè)計,實現(xiàn)了步進(jìn)電機(jī)的開環(huán)控制。在步進(jìn)電機(jī)控制器的設(shè)計中,重點闡述了脈沖產(chǎn)生電路以及對速度的控制。該系統(tǒng)具有成本低、控制方便的特點。關(guān)鍵詞: 單片機(jī); 步進(jìn)電機(jī); 開環(huán)控制
Abstract: The design using ATMEL89C51 single chip to control the step2motor with its controller, driving circuit and LED disp lay circuit to realize step motor open2loop controlwere introduced. For the controller in this design,the circuit to p roduce pulse and the speed controlwere expatiated emphatically. This system possesses features of lower cost, easier control.Key words: single ch ip; step2motor; open2loop con trol
