In the non-overload 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 become 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 microcontroller-based 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 todays stepper motors have been widely used in require high positioning accuracy, high decomposition performance, high responsivene
