What is a step motor breakdown
The step motor drive will drive the current into multiple levels, corresponding to different speed or torque, which will make the motor more stable.
Stepping motor subdivision technology is essentially an electronic damping technology, its main purpose is to weaken or eliminate the low frequency vibration of step motor, improve the operation precision of the machine is only a supplementary function of subdivision technology. For example the stepping Angle is 1.8 °? The two-phase hybrid stepping motor, if the fine fraction of subdivision driver set to 4, then the motor running resolution for each pulse 0.45 °, the precision of the machine can achieve or close to 0.45 °, still depends on the subdivision driver subdivision current control accuracy and other factors. The accuracy of the breakdown drives of different manufacturers may vary greatly; The more accurate the score, the harder it is to control.
Colloquially, a refinement is an increase in accuracy. Default Angle is 1.8 °, stepper motor through segmentation, such as 5 segment Angle is to make five times so that the accuracy increase 5 times into a 0.36 °, which is subdivided, easy to understand
