Speed Control Method of Step Motor Using Harmonic Motion

摘要

The present invention utilizes harmonic motion to realize more stable motor control by preventing the time derivative of acceleration from the acceleration of the motor in the constant speed section and the deceleration section at the constant speed to be infinite (∞) by using harmonic motion. It relates to a speed control method of a step motor.;The present invention draws a circle with a diameter of the maximum speed of the motor, the process of forming a harmonic diagram for the maximum speed by dividing and projecting equally at a predetermined angle to have the number of pulses driving the semicircle, and the harmonic diagram It is equipped with the process of controlling a step motor with the data extracted by it.;Therefore, in the same condition, the driving of the pulse motor using the harmonic motion of the present invention achieves an improved speed control effect because the jerk causing the sudden change of inertia force is maintained at a constant constant value.
