Abstract :
A method is presented for modeling electronically commutated inverter-fed induction motor systems. The machine equivalent network model was derived from the application of Park´s dq0 transformation to the differential equations governing the dynamics of the induction motor. This method resulted in an equivalent system network model which is compatible with most commonly known network analysis software packages. The method was used in the digital simulation of the dynamic steady-state performance of a 204 V, 3-phase, 60-Hz, 1/3-hp, 4-pole induction motor-inverter system. The system was tested in the laboratory under various load conditions. A comparison between a SPICE simulation and experimentally derived test results revealed good agreement between the two sets of data. The model was used in the evaluation of the effects of 180° and 120° electrical inverter conduction periods on the performance of such inverter-machine systems
