Some people ask Xiaobian in the end what is called stepper drive segmentation? What are the special advantages? Similarly, today Xiaobian gives you popular science.
First of all, we have to understand the subdivision of the stepper driver, we must know what is the step Angle, in fact, the step Angle is a pulse signal sent from the control system, the rotation of the stepper motor is to rotate according to this pulse signal, each stepper motor will provide us with a step Angle value when it is delivered. For example, the stepping Angle value given by the stepper motor manufacturer is 9.0°/18°, then we can see that the whole step is 18° and the half step is 9.0, which is the inherent stepping Angle of the stepper motor. However, this step Angle is different in our daily use, so the step Angle has a lot to do with the drive.
The stepper driver transmits the subdivision pulse to the stepper motor, in fact, the step Angle is smaller in this process, such as the stepper driver is in the subdivision state of 20, the real step Angle is only 1/20, and every pulse signal of the step control system is not in the stepper driver when it is working. The stepper motor can only rotate 9.0°, but in the case of the subdivision of the stepper driver 20 subdivisions, the stepper motor only rotates 3.0°. To put it bluntly, the subdivision of the stepper driver is done by the precise control of the current of the stepper driver, and there is not much connection with the stepper motor.
What are the benefits of stepper drive segmentation?
1. Can be a good solution to the vibration of the stepper motor at low speed: this problem can be well solved by subdividing the stepper drive into the motor at low speed when there will be no vibration in the resonance area can also be a good solution to this problem.
2. It can greatly improve the torque of the stepper motor at the output end: especially for the three-phase stepper motor, the effect is better, and it can be increased by more than 50% without subdivision before and after subdivision.
3. Greatly improve the resolution of the stepper motor: because of the use of subdivision self-heating and the stepping Angle becomes smaller, but also greatly improve the uniformity between each step Angle.
Bad after subdivision: The use of data will be very frequent after subdivision, which will greatly improve the CPU usage.
