  <h2>Description <span class="inlinemediaobject"></span></h2>
    <img src="PMDCM_Blocks.png" alt="">
    <p>Model of Separately Excited DC Motor is in the five variants, created by </p>
    <ul type="disc">
        <li><p>Simulink blocks (SEPEX DC Motor Block)</p></li>
        <li><p>S-function Lvel-2 in language C as continous (SEPEX DC Motor continous)</p></li>
        <li><p>S-function Lvel-2 in language C as discrete (SEPEX DC Motor discrete)</p></li>
        <li><p>S-function Lvel-2 in language M as continous (SEPEX DC Motor continous)</p></li>
        <li><p>S-function Lvel-2 in language M as discrete (SEPEX DC Motor discrete)</p></li>
    </ul>
    
  <h2>Data Type Support</h2>
    <p> The block of SEPEX DC Motor accepts only one dimension input signals and any numeric data type supported by Simulink software.</p>

            <dd><p>Table describes parameter as function of field winding current. Table can be defined by rows or columns. First row or column contains data of field winding current. Second row or column contains functions value of field winding current. If table is loaded from Mat-file, then Mat-file must be in the current directory. Linear interpolation is used for estimation actual values.</p></dd>
