Drive after the breakdown of the main advantages are: complete elimination of low frequency oscillation in the motor. Low-frequency oscillation is a stepper motor (especially reactive motor) natural characteristics, segmentation is the only way to eliminate it, if your stepper motor sometimes works in resonance region (such as the ARC), select the segments drive is the only option. Improved the output torque of the motor. Especially responses to three-phase motors, torque ratio when it is not subdivided by about 30–40%. Improve the resolution of the motor. Because the step angle is reduced, increasing the uniformity of step, ' improve the resolution ' is understood.
