For when machine stepper motor under the jitter, make a detailed introduction. Way to control the step motor running is very unique, is controlled by digital signal, in a short time, when the pulse provided to drive, but because of too much from the pulse, leads to the wall of a stepping motor, is the pulse frequency is too high. To solve this problem, the solution is to some, is very simple, as long as before stepping motor start, the pulse frequency to gradually rise, slowing down gradually reduce the pulse frequency. This method is called & otherDeceleration & throughout; Methods. Based on the input pulse signal, the speed of the stepper motor and subject to change with the input pulse signal change. If to a drive signal, the stepper motor will be a subdivision step away from the Angle of rotation. But the problem is coming, if the signal conversion is very fast, so step by step electric opportunity due to the effect of damping of the internal counter electromotive force, locked-rotor and cloth. So at run time, the need to adopt the method of acc, stop to slow down. Stepper motor as a special motor control is very strict, its characteristic is, no rotation step, its inherent step, step by step, from the Angle of running and always the same. So no matter how many times rotation is not there is a continuous cumulative error. Need to choose the appropriate frequency, different in software programming to achieve the best control effect. So for most of the motor, it is difficult to achieve the rotation of the soon. More details on motor also pay attention to four macro electric appliance co. , LTD.
