LabVIEW Simulation of Induction Motors

Abstract Knowledge of steady-state processes of induction motors is critical in the understanding of their operating principle. In addition to the vast, systematic theories in literature, computer simulations provide a keen insight to the mechanism. Suitable modeling methods enable motors to be simulated with various parameters. Many phenomena can be predicted without hardware experimentation. From equivalent circuits of induction motors of different power, this paper gives detailed formulations that can be used to model their steady-state performance. Simulation results are given in LabVIEW, which is a widely-adopted visual modeling platform. Various quantities such as active power, reactive power, power loss, motor slip, are demonstrated at the starting, running, and stopping of inductor motors. These visual simulations have been used by Electronics Engineering technology (EET) students for a clearer understanding of parameters that affect the operation of induction motors.
