Model of Series-wound DC Motor

## Library

Electromechanical Drives

## Description

Model of Series-wound DC Motor is in the five variants, created by

- Simulink blocks (SWDCM Block)

- S-function Lvel-2 in language C as continous (SWDCM continous)

- S-function Lvel-2 in language C as discrete (SWDCM discrete)

- S-function Lvel-2 in language M as continous (SWDCM continous)

- S-function Lvel-2 in language M as discrete (SWDCM discrete)

## Data Type Support

The block of SWDCM accepts only one dimension input signals and any numeric data type supported by Simulink software.

## Parameters and Dialog Box

Input parameters

  Enter the value of parameters or mark checkbox, if you want created new input insted of parameter.

Sample time (Only in discrete type of model)

  Enter the time interval between sample time hits. Model use Euler method.

Buttons Field winding inductance and Magnetic Flux

  This button is define functionality this parameters in new window. Parameter can be define by

  - Table from workspace or from Mat-file.

  - Constant value

  - New input

  Table describes parameter as function of armature current. Table can be defined by rows or columns. First row or column contains data of armature current. Second row or column contains functions value of armature 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.

Non zeros initial conditions

  After this button is clicked, new window is opened. Enter the value of initial state variables. Default values of initial conditions are set to zero.

Output paramters

  You may add another outputs to block.
