Into the 21st century, AC variable speed electric drive system to continue as a major research topic one. MATLAB is a new generation of scientific and engineering computing software, has become the worlds most widely used as one of the most popular software. MATLAB now has more than just a matrix laboratory, it has become a broad prospect of new high-level computer programming language, its universities and research play an important role. MATLAB not only traditional interactive programming capabilities, and provides a rich and reliable matrix operations, graphics rendering, data processing, signal and image processing tools, and its function more and more powerful. In this paper, MATLAB simulation of three-phase induction motor drive characteristics, so that the complicated mathematical treatment efficiency greatly accelerated. Determine the motors magnetic circuit calculation, parameters, performance and starting performance calculation. And make corresponding experiments to verify the correctness of derived parameters. Calculated by electromagnetic motor performance indicators must comply with national standards or r
