What is the principle of step motor drive?
Driven by subdivision stepper motor drives, where the step Angle is small, such as drive work breakdown in 10 state, where the step Angle for "step motor inherent from the Angle of" one over ten, that is to say: 'when a drive to work in step don't segment of the whole state, each hair a step pulse control system, 1.8 ° motor rotation; With subdivision driver work breakdown in 10 state, motor rotation only 0.18 °, which is the basic concept of subdivision. The breakdown function is made entirely by the electric current of the actuator which is controlled by the actuator, which has nothing to do with the motor.
What are the advantages of drive segmentation? Why do you recommend using segmentation? The main advantages of drive segmentation are: eliminating the low frequency oscillation of the motor. Low frequency oscillation is a stepper motor (especially reactive motor) the inherent characteristics of the segment is the only way to eliminate it, if your stepper motor sometimes have to work in the resonance region (arc), select subdivision driver is the only option. The output torque of the motor is improved. In particular, the torque ratio of the three-phase reaction is about 30-40% higher than the non-break. Improved the resolution of the motor. By reducing the Angle of the step and increasing the evenness of the step distance, the "increase the resolution of the motor" is self-evident.
Stepper motor is a kind of as control with special motor, its rotation is a fixed Angle (called "step Angle") running step by step, at the same time, its characteristic is no accumulated error (accuracy of 100%), so widely used in all kinds of open loop control. The operation of the stepping motor to one electronic device drivers, the device is stepper motor drives, it is the control system of the pulse signal into angular displacement of stepper motor, or: each send a pulse signal control system, through the drive to spin stepper motor step Angle. So the speed of the step motor is proportional to the frequency of the pulse signal. Therefore, the frequency of the control step in the pulse signal can be controlled accurately by the motor. The purpose of the precise positioning of the motor is to control the number of the step pulse.
