Provided is a method and apparatus for simulating the behavior and operation of a three-phase induction machine. The present invention provides for a digital simulating device for simulating the behavior and operation of three-phase induction machines in accordance with selected parameters. There is further provided a computer modeling method for behavioral and operational analysis which utilizes blocks and super-blocks connected with signals as in physical systems. The modeling method incorporates an algebraicly simplified set of equations in stationary 2-axes reference frame.
