What is stepper motor subdivision?
For a two phase hybrid stepper motor with a step angle of 1.8 degrees, for example, if the fine fraction of the subdivision drive is set to 4, then the motor resolution is 0.45 degrees per pulse,
The subdivision technology of stepping motor is essentially an electronic damping technology, whose main purpose is to reduce or eliminate the low frequency vibration of stepping motors, and to improve the running accuracy of motors. It is only a subsidiary function of subdivision technology
Motor accuracy can reach or close to 0.45 degrees, but also depends on the subdivision driver, subdivision current, control accuracy and other factors. The accuracy of subdivision drivers of different manufacturers may vary greatly; the larger the fraction is, the more difficult it is to control the accuracy.
Fine fraction of stepper motor drives.There are three kinds of segmentation methods1, 2, N times, such as 2, 4, 8, 16, 256, 32, 64, 128, and d.,An integer multiple of 2 and 5, such as 5, 10, 20, 25, 200, 40, 50, 100, and d.,An integer multiple of 3 and 3, such as 3, 6, 9, 12, 24, 48, and subdivision.
