In foreign countries, to step into the system, mainly adopts two-phase hybrid stepping motor and stepper motor drives. but in domestic, the masses of users know about subdivision is not special, just think, just in order to improve the accuracy of segment, actually otherwise, segmentation is mainly in order to improve the running performance of the motor is now shows as follows: stepping motor subdivision control is precisely controlled by the driver of stepping motor phase current, the two-phase motor, for example, if the rated current of motor is 3 a, if you are using a conventional drives (Such as commonly used way of constant current chopper)Every step driving the motor, the motor running, in its winding current from 0 mutation into 3 a or 3 a mutation to 0, the great changes in phase current, is bound to cause noise and vibration of the motor running. if you are using subdivision driver, under the conditions of 10 subdivision drive the motor, step motor per run in micro, current changes in the winding is only 0. Rather than 3 a, 3 a and law of electric current is a sine curve changes, thus greatly improve the motor vibration and noise, therefore, on the performance of advantages is the real advantages of segmentation. the subdivision driver to precisely control the motor phase current, so the driver should have quite high technical requirements and technical requirements, the cost will also be higher. Note that some domestic drives using smooth instead of segmentation, some also calls the segmentation, but these are not real niche, want to distinguish the two different nature. 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.
