Tips: The role of stepper driver’s subdivision
Major advantages of subdivided driver: Low frequency oscillation of motor is completely eliminated. Low frequency oscillation is the intrinsic characteristic of the stepper motor (especially VR motor). However, subdivision is the only way to eliminate it. If your stepper motor has to work at resonance region (e.g.: run arc) sometimes, it is the only choice to choose subdivided driver to increase the output torque of the motor. Especially for 3-phse VR motor, its torque is increased by about 30-40% when not subdivided. Thus, the resolution of the motor is increased. With the stepping angle reduced and uniformity of the step pitch increased, the resolution of the motor is self-evident. The main role of stepper motor driver’s subdivision is to enhance the accuracy of the stepper motor.
