In the case of non-overloaded, the motor speed, stop position depends only on the pulse frequency and pulse number, regardless of load changes, when the driver receives a step pulse signal, it will drive a stepper motor to Set the direction of rotation of a fixed angle, called the step angle, which the angle of rotation is fixed step by step operation. Number of pulses can be controlled by controlling the angular displacement, so as to achieve accurate positioning purposes; the same time by controlling the pulse frequency to control the motor rotation speed and acceleration, to achieve speed control purposes.Work:Induction motor is a stepper motor, does it work is the use of electronic circuits, the DC power supply into a time-sharing, multi-phase timing control current, this current stepper motor power supply, the stepper motor to work properly , The drive is sharing power supply for the stepper motor, the polyphase timing controllerAlthough the stepper motor has been widely used, but the stepper motor does not like a normal DC motor, AC motor in the conventional use. It must be double-ring pulse signal, power driver circuit composed of the control system can be used. Therefore, it is not easy with a good stepping motor, which involves mechanical, electrical, electronics and computers, and many other specialized knowledge.As the stepper motor actuators, electromechanical integration, one of the key products, widely used in a variety of automatic control systems. With the development of microelectronics and computer technology, increasing demand for stepper motor, has applications in all areas of the national economy.步進(jìn)電機是將電脈沖信號轉(zhuǎn)變?yōu)榻俏灰苹蚓€位移的開環(huán)控制元步進(jìn)電機件。在非超載的情況下，電機的轉(zhuǎn)速、停止的位置只取決于脈沖信號的頻率和脈沖數(shù)，而不受負(fù)載變化的影響，當(dāng)步進(jìn)驅(qū)動器接收到一個脈沖信號，它就驅(qū)動步進(jìn)電機按設(shè)定的方向轉(zhuǎn)動一個固定的角度，稱為“步距角”，它的旋轉(zhuǎn)是以固定的角度一步一步運行的?？梢酝ㄟ^控制脈沖個數(shù)來控制角位移量，從而達(dá)到準(zhǔn)確定位的目的；同時可以通過控制脈沖頻率來控制電機轉(zhuǎn)動的速度和加速度，從而達(dá)到調(diào)速的目的。工作原理步進(jìn)電機是一種感應(yīng)電機，它的工作原理是利用電子電路，將直流電變成分時供電的，多相時序控制電流，用這種電流為步進(jìn)電機供電，步進(jìn)電機才能正常工作，驅(qū)動器就是為步進(jìn)電機分時供電的，多相時序控制器 雖然步進(jìn)電機已被廣泛地應(yīng)用，但步進(jìn)電機并不能象普通的直流電機，交流電機在常規(guī)下使用。它必須由雙環(huán)形脈沖信號、功率驅(qū)動電路等組成控制系統(tǒng)方可使用。因此用好步進(jìn)電機卻非易事，它涉及到機械、電機、電子及計算機等許多專業(yè)知識。 步進(jìn)電機作為執(zhí)行元件，是機電一體化的關(guān)鍵產(chǎn)品之一, 廣泛應(yīng)用在各種自動化控制系統(tǒng)中。隨著微電子和計算機技術(shù)的發(fā)展，步進(jìn)電機的需求量與日俱增，在各個國民經(jīng)濟(jì)領(lǐng)域都有應(yīng)用。
