Can the subdivision of a subdivision drive represent accuracy?
Improving the running accuracy of the motor is only a subsidiary function of the subdivision technique. For example, for a two phase hybrid stepping motor with a step angle of 1.8, the fine fraction of the subdivided drive is set to 4,
Then, the resolution of the motor is 0.45 degrees per pulse, and the accuracy of the motor can reach or close to 0.45 degrees. It also depends on the Subdivision Current of the subdivision drive, the 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.
Stepper motor subdivision technology is essentially an electronic damping technology (please refer to the relevant literature), the main purpose is to reduce or eliminate the low-frequency vibration of stepper motor
