摘要：Different types of models have been proposed in the recent years to examine different problems associated with induction motors. These models are from the simple equivalent circuit to complex d, q models and abc models which allow the inclusion of different forms of impedance and/or voltage unbalance. In the recent past, hybrid models have been developed which allow the inclusion of supply side unbalance but with the computational economy of the d, q models. Recently, there are so many applications in which induction motors are fed by static frequency inverters. Such applications are growing fast and a significant work in this field has already been done. However, still there are a lot of scopes left which may be used in this applications. This paper presents a dynamic model using PWM inverter and mathematical modelling of the motor. By using this model induction motor may be used as variable speed applications unlike conventional induction motors. The utilization of squirrel cage induction motors with electronic inverters presents greater advantages on cost and energy efficiency, compared with other industrial solutions for varying speed applications. The dynamic simulation of the small power induction motor is one of the key steps in the validation of the design process of the motor drive system and it is needed for eliminating in advertent design mistakes and the resulting error in the prototype construction and testing. This model is successfully used in the fault detection of rotor broken bar for the induction machines. This paper demonstrates the simulation of steady-state performance of three phase squirrel cage induction motor and detection of rotor broken bar fault by MATLAB program.
