There is no accumulated error in stepping motor. How do you understand this?
So let's say the cumulative error, which is that the error can be added up, like the starting point is 0.01 degrees and it's going to be 0.02 degrees. It means that the Angle of the step motor depends on the pulse of the drive, and it corresponds to a certain Angle. So after spinning a certain amount of rotation, even if there is a small error (like the uneven tooth of the processing process), it is not cumulative.
Explanation: The step motor has periodic error: the pole is not aligned. There is no cumulative error: it returns to its original position, regardless of the magnetic polarity. If the first circle error 5 ° So is 355 degrees The second circle is 355 plus 360 degrees The third circle is 355 plus 720 degrees
The precision of stepper motor is not cumulative error performance of each step before and in theory should be in the position and has nothing to do every step of the error, such as stepper motor step Angle is 1.8 °, accuracy of 5%, is the practical and theoretical positions of each step should be to the Angle between the location of the error range within the 5% of interval Angle, every step is the Angle of the theory of location and position deviation within 0.09 °.
