How to use the MATLAB code for Electric Machines examples:


In order to use the “The Electrical machines examples – matlab code” please follow the next steps:

1. Copy the folder E_Machines from the book CD in your computer (this is necessary only at the first use)
2. Open the MATLAB
3. Set the MATLAB Current directory through yours folder ( ...\E_Machines)
4. Write: “examples” in the matlab Command Window
5. Chose one example from application interface menu.

The examples are structured in the following categories:

A. Transformer
Example 1 – Magnetic circuit
Example 2 – Transformer steady state
Example 3 – Transformer unbalanced load current
Example 4 – Transformer unbalanced load impedance

B. DC steady state motor
Example 5 – Separated excited DC motor
Example 6 – Series excited DC motor

C. AC motor steady state
Example 7 – Induction motor characteristic
Example 8 – Synchronous motor characteristic
	
D. Transients
Example 9a – No load transformer – grid connection
Example 9b – Loaded transformer – grid connection
Example 10 – DC motor transients
Example 11 – Induction motor transients
Example 12 – Synchronous motor transients

E. Optimal design
Example 13 – Induction motor by H. J. algorithm
Example 14 – Induction motor by GA
Example 15 – Synchronous motor by H. J. algorithm
Example 16 – Synchronous motor by GA

The first eight examples are simple application developed in matlab code. The user has to introduce its own data in the application interface and run the program from application interface. The results computation results are shown also through application interface.
The transient examples are developed in MATLAB simulink.
The optimal design examples are complex and introduce the user desired parameter and showing the design results is based on input output files which could be open from the application interface.


Note: The specified examples were developed with MATLAB/Simulink version 6.5.
