How to adjust the speed of the step motor
Stepper motor shaft rotation speed, drive without segmentation with the input pulse frequency is proportional to the control of the input pulse frequency control the shaft speed, so to reach the purpose of the stepper motor speed!
You can change the time delay length of the phase sequence directly if the interval is too short and the step too long may be too long Another is that the PWM can be converted to a space ratio when the step motor is driven by a drive chip
There is a certain extent to the speed of the step motor. Generally speaking no speed, only the step Angle, the frequency and the pull frequency. In order to adjust the speed, we need to talk about the several phases of the control step motor. When it comes to several shots, it's about how often it works. The faster you can control the motor, the shorter the time it takes to move one step into the corner, and the faster it will turn into the motor. If the frequency of your control is fixed, then the next phase of the beat determines the next step in the Angle. That's how fast the next phase of the action will be. Of course, the fastest time is not less than the period of the control phase. Finally: Let's say that one set of pulse signals move a step into the corner, and the faster the next set of pulses come, the faster they move. In contrast, the slower the next set of pulses came, the slower they went. Adjust the interval time of each set of pulses to achieve the speed of the adjustment step motor.
