【正文】 s stepper motor rotation direction by setting a fixed point of view (and the step angle). You can control the number of pulses to control the amount of angular displacement, so as to achieve the purpose of accurate positioning?？刂破鞯姆较蛐盘枦Q定步進電機的順時針或逆時針旋轉(zhuǎn)。噪音大，無定為轉(zhuǎn)距已大量淘汰。如對于步距角為 176。 空載啟動頻率：即步進電機在空載情況下能夠正常啟動的脈沖頻率，如果脈沖頻率高于該值，電機不能正常啟動，可能發(fā)生丟步或堵轉(zhuǎn)。當定子的矢量磁場旋轉(zhuǎn)一個角度。, the precision of motor can reach or close to 176。, also depends on the breakdown of the breakdown of the drive current control accuracy and other factors, the breakdown of the number of the more difficult the greater the precision of control. 步進電機是一種將電脈沖轉(zhuǎn)化為角位移的執(zhí)行機構(gòu)。轉(zhuǎn)子也隨著該磁場轉(zhuǎn)一個角度。在有負載的情況下，啟動頻率應(yīng)更低。減少噪音。 反應(yīng)式（ VR),國內(nèi)一般叫 BF，常見的有三相反應(yīng)式，步距角為 ；也有五相反應(yīng)式。步進電機轉(zhuǎn)速的高低、升速或降速、啟動或停止都完全取決于脈沖的有無或頻率的高低。 At the same time, you can by controlling the pulse frequency to control the motor rotation speed and acceleration, so as to achieve the purpose of speed. Stepper motor directly from the ACDC power supply, and must use special equipment stepper motor drive. Stepper motor drive system performance, in addition to their own performance with the motor on the outside, but also to a large extent depend on the drive is good or bad. A typical stepper motor drive system is operated by the stepper motor controller, stepper motor drives and stepper motor body is posed of three parts. Stepper motor controller stepper pulse and direction signal, each made of a pulse, stepper motordriven stepper motor drives a rotor rotating step angle, that is, stepbystep further. High or low speed stepper motor, or speed, or deceleration, start or stop pulses are entirely dependent on whether the level or frequency. Decide the direction of
