Stepper motor stepper motor drives 3 big drive mode: 1, the whole step step in the whole operation of drivers, the same kind of stepping motor can match both full/half step drive also can match subdivision driver, but the running effect is different. Stepper motor drive by pulse direction/instruction on the two two phase stepper motor excitation coil cycle (The charging coil set current)Each pulse, this kind of drive mode will make a basic step motor mobile pitch Angle, which is 1. 80 degrees (Standard two-phase motor once a total of 200 steps from the Angle of)。 Step 2 and a half drive when single-phase excitation, step motor shaft stop to the whole position, drive after receiving the next pulse, such as to another phase excitation and keep the original one after another in excitation state, the motor shaft will move from a half step Angle, stopped in the middle of the adjacent two whole step position. So cycle to single phase and two phase coil bipolar excitation stepper motor will with each pulse 0. 90 - degree rotation half step way. Han debao electrical supply all full/half step drive steps can perform the whole and half drive, dial the code switch by the driver of the dial to choose. Compared to the whole step mode, half step way are twice as high accuracy and the advantages of small vibration during low speed running, so the actual when using the full/half step drive half step is generally selected mode. 3, minimal subdivided driving subdivided driving mode with low speed vibration and two positioning accuracy is high. For sometimes need to run at low speed (The motor shaft and sometimes work in the RPM of 60)Or positioning accuracy is less than 0. 90 degrees of stepping applications, the subdivision type stepping motor drives for a wide range of applications. Its basic principle is to two of the motor coil respectively according to the steps of the sine and cosine shape precision current control, thus making a step away from the Angle of step distance is divided into several segments. Such as drive mode can make the segmentation of 16 step each lap 200 standard stepper motor to achieve each lap 16 = 200 * 3200 steps run precision (Is 0. 1125°)。 Driving mode of the three step whole, half step, segment the main difference is that the control precision of the motor coil current (The excitation mode)。
