摘要

步進(jìn)電機(jī)是將電脈沖信號(hào)轉(zhuǎn)變?yōu)榻俏灰苹蚓€位移的開(kāi)環(huán)控制元件。在非超載的情況下,電機(jī)的轉(zhuǎn)速、停止的位置只取決于脈沖信號(hào)的頻率和脈沖數(shù),而不受負(fù)載變化的影響,即給電機(jī)加一個(gè)脈沖信號(hào),電機(jī)則轉(zhuǎn)過(guò)一個(gè)步距角。這一線性關(guān)系的存在,加上步進(jìn)電機(jī)只有周期性的誤差而無(wú)累積誤差等特點(diǎn),使得在速度、位置等控制領(lǐng)域用步進(jìn)電機(jī)來(lái)控制變得非常的簡(jiǎn)單。步進(jìn)電機(jī)的調(diào)速一般是改變輸入步進(jìn)電機(jī)的脈沖的頻率來(lái)實(shí)現(xiàn)的。因?yàn)槊拷o一個(gè)脈沖步進(jìn)電機(jī)就轉(zhuǎn)動(dòng)一個(gè)固定的角度,這樣就可以通過(guò)控制步進(jìn)電機(jī)的一個(gè)脈沖到下一個(gè)脈沖的時(shí)間間隔來(lái)改變脈沖的頻率,以延時(shí)的長(zhǎng)短來(lái)具體控制步進(jìn)角來(lái)改變電機(jī)的轉(zhuǎn)速,從而實(shí)現(xiàn)步進(jìn)電機(jī)的調(diào)速。在本設(shè)計(jì)方案中采用STC12C5A32AD型單片機(jī)內(nèi)部的定時(shí)器改變CP脈沖的頻率實(shí)現(xiàn)對(duì)步進(jìn)電機(jī)的轉(zhuǎn)速進(jìn)行控制,同時(shí)通過(guò)編程決定脈沖發(fā)生個(gè)數(shù)來(lái)實(shí)現(xiàn)位置的精確定位。

Designed of Stepping Motor Controller for the Terminals Connecting System

ABSTRACT

Stepping motor is the open loop control component which transforms electrical signals to angular or line displacement. In the none overload of circumstances,the speed of stepping motor only depends on the frequency of the pulse signal,while the stop position depends on the pulse count,but not the load.It is to say that the stepping motor turns a step angle when given a pulse signal.The existence of linear relationship between  the pulse count and the displacement, and a step-motor only periodically Error while no accumulated error,that make it easy to use stepper motor to control in the speed and position control Field.The stepping motor Speed is generally change with the frequency of the input pulse signal.For each pulse signal,the stepping motor will turn a fixed angel. we can control the legth of time between two pulses to change the frequency of the pulses, so as to realize the stepper motor speed.In This design the internal timer of the STC12C5A32AD type of single-chip was adoptted to generate a series of changable frequency pulses to speed the stepper motor. While the number of pulses generating decided by programming to accurately position.
