Model of AC Induction Motor

## Library

Electromechanical Drives

## Description

Model of AC Induction Motor is in the five variants, created by

- Simulink blocks (AC Induction Motor Block)

- S-function Lvel-2 in language C as continous (AC Induction Motor C continous)

- S-function Lvel-2 in language C as discrete (AC Induction Motor C discrete)

- S-function Lvel-2 in language M as continous (AC Induction Motor M continous)

- S-function Lvel-2 in language M as discrete (AC Induction Motor M discrete)

You can choose type T, Gamma or Inverse Gamma model. Inside structure is allways T-model with transfomation to chosen type.

## Data Type Support

The block of Asynchronous motor accepts only one dimension input signals and any numeric data type supported by Simulink software. Outputs Stator flux and Rotor flux are complex signals.

## Parameters and Dialog Box

Type of model

  Choose one of T, Gamma or Inverse Gamma model.

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.

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.
