What is stepping motor fine fraction?
The accuracy of subdivision drivers of different manufacturers may vary greatly; the larger the fraction is, the more difficult it is to control the accuracyThe fine fraction of stepper motor drivesThere are three kinds of segmentation methods1, 2, N times, such as 2, 4, 8, 16, 256, 32, 64, 128, and d.,An integer multiple of 2 and 5, such as 5, 10, 20, 25, 200, 40, 50, 100, and d.,An integer multiple of 3 and 3, such as 3, 6, 9, 12, 24, 48, and subdivision
For example for the step angle is 1.8 degrees? The two-phase hybrid stepping motor, if the fine fraction set subdivision driver is 4, then the operation of the motor resolution is 0.45 degree per pulse, the precision of motor can achieve or close to 0.45 degrees, also depends on the subdivision subdivision drive current control accuracy and other factors.
The subdivision technology of stepping motor is essentially an electronic damping technology, whose main purpose is to reduce or eliminate the low frequency vibration of stepping motors, and to improve the running accuracy of motors. It is only a subsidiary function of subdivision technology
