CONCEPTS:<\/strong><\/span><\/span><\/span>\"\"<\/a>A Stepper Motor is a brushless<\/strong> direct current motor intended for use in controlled mechanical movement and precision systems.<\/span><\/span> This motor moves in steps from 0 to 360 degrees<\/strong>.<\/span><\/span> It is composed of a stator<\/strong> with paired windings arranged to give a 4-term connectivity (with or without common point<\/em>) and grooves in the air gap to obtain the rotation in degrees.<\/span><\/span> <\/span><\/h4>\n

The rotor<\/strong> is a powerful magnet, also ribbed.<\/span><\/span> The movement is obtained by applying a sequence of pulses<\/strong> to the four terminals of the stator winding, this sequence is called a pulse pattern<\/strong> that must be applied continuously.<\/span><\/span> <\/span><\/p>\n

\"WhatVarieties:<\/span><\/span> <\/span><\/strong><\/p>\n

Regarding the structure<\/strong><\/em> of the rotor winding, there are two types to obtain different powers and control structures:<\/span><\/span> <\/span><\/p>\n

    \n
  1. Bipolar<\/strong>, where the two ends of each of the two windings, called A+, A-, B+, B-<\/strong>.<\/span><\/span> , They are free.<\/span><\/span><\/span><\/li>\n
  2. Bipolar with COMMON POINT<\/strong>: the two coils have a common point that is connected to ground A+, A-, B+, B- and GND<\/strong>.<\/span><\/span><\/span><\/li>\n<\/ol>\n

    Regarding its use<\/strong><\/em>, there are three standard types:<\/span><\/span> <\/span><\/p>\n

      \n
    1. Full step:<\/strong> The rotor moves with less precision facing the grooves.<\/span><\/span> <\/span><\/li>\n
    2. half step<\/strong>: Greater precision is obtained: The rotor is trimmed in the grooves and in the middle<\/strong> of them.<\/span><\/span> <\/span><\/li>\n
    3. Microstepping:<\/strong> with this system you obtain a continuous movement in steps.<\/span><\/span> Its principle is to apply micropulses of advance between groove<\/em>s.<\/span><\/span> For this movement, extra hardware is required and therefore a specific control.<\/span><\/span><\/span><\/li>\n<\/ol>\n

      \"\"<\/a>PURPOSE:<\/strong> <\/span><\/span><\/span><\/p>\n

      This project is based on a desk<\/strong> with all the controls to make simulations<\/strong> <\/em>of rotation patterns on the motor terminals A+, B+, B- and B\u2013<\/strong> here called respectively A, B, 1, 2.<\/strong> The desk is divided into two parts:\u00a0 <\/span><\/span><\/span><\/p>\n

        \n
      1. Upper,<\/strong> there is the motor with access to its terminals whose sequence of patterns<\/strong> can be programmed simply by pressing the switches<\/strong>. In this way you can obtain all types of movements: FULLSEPPING, HALFSTEPPING and others<\/strong>. Practicing with invented patterns can be a curious and instructive experience. The complete sequence is 16 positions<\/strong>. At the top, 16 LEDs show the rotation point at all times. A series of patterns are included in the scheme<\/strong>. In the green band there are some typical rotation patterns and in the red band there are experimental patterns. <\/span><\/span><\/span><\/li>\n
      2. Below<\/strong> are the controls that we detail whose function we detail:<\/span><\/span><\/span><\/span>\n
