Stepper motor & # 8203; Stepping motor drives the main role of the segment is to improve the accuracy of stepper motor. Domestic some drive selection & other; Smooth & throughout; Instead of segmentation, and some also called subdivision, but this is not true segmentation, hope the broad masses of users must distinguish the essence of the difference: 1, & otherSmooth & throughout; Is not accurate control of the motor phase current, only the current rate of change slow some, so & other; Smooth & throughout; Does not occur micro step, and the subdivision microstep can be used for accurate positioning. After 2, motor phase current is smooth, can cause the drop of the motor torque and subdivided control not only do not cause the decline of motor torque, on the contrary, the torque will be increased. Drive subdivided main strengths is: eliminate the low frequency vibration of the motor. Low frequency vibration is stepping motor (Especially the reactive motor)The intrinsic characteristics of, and segmentation is the only way to eliminate it, if your stepper motor to work in the resonance region (sometimesSuch as arc), choose segmentation is one of the selected drive. To improve the output torque of the motor. Especially for three-phase reactive motor, the torque increases by about 30 - than when not subdivided40%. To improve the resolution of the motor. Because of reduced the step Angle, improved the interval evenness, & lsquo; To improve the resolution of the motor & lsquo; Is obvious. Many users mistakenly assume that the higher the segmentation of stepper motor drives, the higher the accuracy of stepper motor, electrical engineer advises clients in fact this is a wrong idea, such as stepper motor subdivision drive higher to reach the 60000 pulses a turn, and practice of stepper motor is unable to distinguish the accuracy, when the drive is set to 60000 pulses/roll, under several pulse stepper motor drives, stepper motor step, this does not improve the accuracy of stepper motor. Stepping motor subdivision skills is essentially an electronic damping, its main intent is to weaken or eliminate the low frequency vibration of step motor, improve the operation precision of the motor subdivision skills of only one function, by the way. Segment after the practice of the motor run time interval Angle is one of the basic steps from the Angle of a few minutes. Two phase stepper motor is apart from the Angle of the basics is 1. 8°1, that is, a pulse. 8°, if do not have a segment, it is 200 pulse walk 360 & deg; , segmentation is a drive by what happens to accurately control the motor phase current, has nothing to do with the motor, if be 10 subdivision, send a pulse motor is 0. 18°, namely 2000 pulse walk 360 & deg; , the accuracy of the motor can reach or near zero. 18°, but also on subdivision driver subdivision current control accuracy and other elements. Different manufacturers of subdivision drive accuracy may vary widely; The more difficult it is to fine grade, the greater the precision control. Etc. Three-phase stepper motor from the Angle of the basics is 1. 2°1, that is, a pulse. 2°, if do not have a segment, it is 300 pulse walk 360 & deg; , if is 10 subdivision, send a pulse, motor 0. 12°, namely 3000 pulse walk 360 & deg; , etc. Practice when used in motor, the demand is higher, if the speed and the precision and stability requirement is not high, don't have to choose high subdivision. When used in practice, if the speed is very low case, should choose large subdivision, guarantee the smooth, reduce vibration and noise.
