Speed-up and Speed-down Controller of Step Motor Based on SCM
In order to prevent the locked rotor, step-out and super ledge speed control of step motor, speed-up and speed-down control to the step motor should be carried out. Based on the speed -up curve analysis, using of symmetrical design, this paper has simplified the speed-up and speed-down curve. In order to achieve real-time computing exponential curve in SCM, using the method of constant duration and control pulses, speed-up and speed-down control, exponentially, are achieved, and, the connections between step motor and drive and circuit have been designed.
