The study of subdivided driving technology is very active, both at home and abroad high performance subdivision driver circuit, can be subdivided into thousands or even any subdivision. Can now be subdivided by complex computing steps from the Angle of uniform, greatly improving the pulse resolution of stepping motor, reduce or eliminate the shock and noise and torque ripple, the stepper motor is more 'step' class features. The segmentation technology and stepper motor relationship: to improve the precision of 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. Segment after the resolution of the motor operation for each pulse raised, but running accuracy can reach or close to the pulse resolution still depends on the subdivision driver subdivision current control accuracy and other factors. Different manufacturers of subdivision drive accuracy may vary widely; The more difficult it is to fine grade, the greater the precision control. Real segment to drive has very high technical requirements and technical requirements, the cost will be higher. Domestic some drive to 'smooth' the motor phase current is used to replace the segmentation, belong to 'false segmentation', 'smooth' does not produce micro step, will cause the motor torque decline. Real subdivided control not only do not cause the decline of motor torque, on the contrary, the torque will be increased. To actually step away from the Angle of function: when no subdivision driver, user mainly by choosing the number of different phase stepping motor to meet your requirement for interval Angle. If using subdivision driver, users only need to change the fine fraction on the drive, can greatly change the actual interval Angle, the stepping motor of the 'phase number interval Angle to change the actual effect is almost negligible. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
