In foreign countries, to step into the system, mainly adopts two-phase hybrid stepping motor and the corresponding subdivision driver. But in domestic, the masses of users to understand 'segmentation' is not special, just think, segmentation is in order to improve the accuracy, actually otherwise, segmentation mainly is to improve the performance of the motor, the instructions are 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 will mutations from 0 to 3 a or 3 a mutation to 0, the great changes in phase current, is bound to cause vibration and noise of motor running. If using subdivision driver, under the conditions of 10 subdivision drive the motor, step motor each run a 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. Because 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. 'Smooth' is not accurate control of the motor phase current, but the rate of change of the current slow some, so 'smooth' do not produce micro step, and subdivision microstep can be used for accurate positioning. After motor phase current is smooth, can cause the drop of the motor torque control and not only do not cause the decline of motor torque, on the contrary, the torque will be increased. 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.
