What is the principle of subdivision of step motor drive?
Used in stepper motor step Angle can not meet the conditions, the subdivision driver can be used to drive the stepper motor, the principle of subdivision driver is by changing the size of the adjacent (A, B) current, to change the synthesis of the Angle of the magnetic field to control the step motor running. So current control technology is the key to the breakdown drive.
A motor's feet are fixed. The subdivision is just A little bit of the current, the whole thing is the 0a-1a, and the two subdivisions are just adding A state 0A - 0.707 a-1a. The higher the segmentation, the more stable the current standard. Take a pulse, and the drive check table corresponds to changing the current of AB. There is no such thing as a few actions
Transform the order of electricity in a pulse? You got it wrong, So-called subdivision control, like, in a step away from the Angle of cycle, I let the control voltage in some points remain unchanged, unchanged, the motor is stop, in this way, just as I have more can make the motor stop points, where is just like a step Angle is divided into a number of. In the case of control, only when the motor actually moves to a step Angle is changed
Frequency, frequency? I don't know what you're asking. That's the principle. The concrete method is more complicated, my level is limited, hehe.
