Study abroad subdivision drive technology is very active, high-performance segment driver circuit can be broken down into thousands or even any subdivision. Now able to do so through a complex calculation step angle after the breakdown of uniform, greatly improving the resolution of the stepper motor pulse, reducing or eliminating the shock, noise and torque ripple, the stepper motor more "servo type" feature.

Subdivision technology and the stepper motor to improve the accuracy of the relationship: Subdivision stepper motor is essentially an electronic damping technology, its main purpose is to weaken or eliminate low-frequency vibration of the stepper motor to improve the accuracy of the motor is running fine an incidental feature points technology.

After the breakdown of the motor to increase the resolution of each pulse when running, but running accuracy can reach or approach the pulse resolution also depends on other factors subdivision subdivision drive current control accuracy. Breakdown of different manufacturers drive accuracy may vary greatly; greater the precision of the more difficult to control the number of segments.

The real breakdown of the drive to have a very high technical requirements and process requirements, the cost will be higher. Some drives domestic use of motor phase current "smooth" process to replace the subdivision, a "false breakdown", "smooth" does not produce micro-step, it will cause a decline in motor torque. The real subdivision control not only does not cause a decline in motor torque, on the contrary, the torque will increase.

The actual step angle effect: in the absence of sub-drive, the user mainly by selecting a different number of phases of the stepper motor to meet their own requirements on the step angle. If you use a sub-drive, the user simply by changing the number of segments on the drive, you can dramatically change the actual step angle stepping motor 'phases' to change the role of the actual step angle is almost negligible.
