In the nonoverload case, the motor speed, and stop location depends only on pulse frequency and pulse number, without the load change, that is, to add an electrical pulse signal, a step motor is turned away from the corner. The existence of this linear relationship, coupled with only a periodic error of stepper motors without the accumulated error and so on. Made in terms of speed, position and other control areas to control the stepper motor used bee very simple. Stepper motor speed control in general is to change the input frequency of stepper motor pulses to achieve the stepper motor speed, because the stepper motor to a pulse on each rotation a fixed angle, so that you can by controlling the stepper motor a pulse to the next a pulse time interval to change the pulse frequency, the length of delay to specific controls to change the angle stepper motor speed, in order to achieve speed control stepper motor. In this design the use of AT89C51 microcontrollerbased timer to change the internal pulse frequency of CP in order to achieve the speed of stepper motor control, motor speed and the realization of positive inversion functions. Preface Stepper motors in 1920 was first developed by the British. Late 1950 invention of the transistor is gradually applied to stepper motor, which controls for the digital easier. Through continuous improvement in the future, makes today39。但由鍵盤輸入的速度數(shù)值了得通過顯示器來顯示，固本次設(shè)計要兩排顯示，一排來顯示給定的轉(zhuǎn)速一排來顯示實際的轉(zhuǎn)速。三 控制的測定因本次設(shè)計的要求，選用三相三拍步進電機，單片機選用89C51作為控制器。二 步進電機詳細調(diào)速原理 步進電機的調(diào)速一般是改變輸入步進電機的脈沖的頻率來實現(xiàn)步進電機的調(diào)速，因
