In order to run this simulation package, these steps must first be followed:

1. Press the link    MACSIM    (short for Machine Simulation) to download and save the <> file on disk in a directory (folder) of your choosing.

2. Open this directory and extract (unzip) from <> the imbedded mdl- and m- files as well as others, placing them for convenience in the same folder. To unzip or decompress this file, you may use a program such as WinZip or Stuffit (available on the web at and; you may also use the unzip function in MATLAB.

3. Load your MATLAB program. Although the m- and mdl- files have been saved using MATLAB version 7.11 (R2010b) and Simulink version7.6, this package is compatible with older releases. Specifically, Simulink files can be resaved after selecting the pertinent model type from a list of versions ranging from R14 to R2009.(To download  the original package which runs under MATLAB (R13) now obsolete, press the link MACSIMold )

4. It is advisable that your chosen directory be added to the MATLAB search path. Otherwise, be sure that the directory is established as your current working directory. 

5. At the MATLAB prompt, type and enter         contents       to bring forth a menu-driven table of contents.

6. Select a demo and run it.

Once this process is completed, you need only to follow steps 5 and 6 to run the various simulations.

The link   VIDEOS   accesses a series of video clips dealing with the motion of electric machines, space vectors, and  magnetic field distributions. These .avi files have been developed using Matlab/Simulink but are to be run separately with a Video Player. 

The link   ANIMATIONS   retrieves an identical set of pictures in motion as developed in the above Video link but now converted to animated gif files in the html format to be run on the web.

Clicking the icon   or the link APPLETS locates another set of animations developed using GeoGebra.

The link   WWW   provides a listing of useful websites which present animations of electric machines dealing with their construction, operation and characteristics, including mathematical models and underlying physical principles.

The link   TOUR  downloads the <tour.wav> audio file which can then be run on any player in order to listen to a brief introduction to the simulation package.

I look forward to receiving your comments, suggestions, and corrections regarding this package so that I may incorporate them in future updates. The <> file was last modified on November 6, 2011.
