The steps, methods and application process of stepper motor driver to realize drive control
Feed pulse → pulse mixing circuit → addition and subtraction pulse distribution circuit → acceleration and deceleration circuit → ring distributor → power amplifier → stepper motor winding.
1. The pulse mixing circuit mixes pulse feed, manual return to origin, error compensation, etc. into positive and negative pulse feed signals;
2. The addition and subtraction pulse distribution circuit synthesizes the simultaneous positive and negative pulses into one-way feed pulses;
3. The acceleration and deceleration circuit adjusts the pulses to pulses that conform to the acceleration and deceleration characteristics of the stepper motor. The frequency changes must be stable and the acceleration and deceleration have a certain time constant;
4. The ring distributor converts the passing pulses into level signals to control the on and off of the stator winding of the stepper motor;
5. The milliamp level current output by the power amplifier ring distribution output device is used for power amplification, and is generally composed of a preamplifier and a power amplifier.
A stepper motor is an open-loop control element that converts electrical pulse signals into angular displacement or linear displacement. Under non-overload conditions, the motor's speed and stop position only depend on the frequency and number of pulses of the pulse signal and are not affected by load changes. That is, a pulse signal is added to the motor and the motor rotates by a step angle. The existence of this linear relationship, coupled with the fact that stepper motors only have periodic errors and no cumulative errors. It makes it very simple to control using stepper motors in control areas such as speed and position.
