Abstract

This thesis presents an analysis of losses in an induction motor with field oriented control, supplied by an indirect frequency converter with a voltage source DC link. The introductory part describes the individual types of electric drives and provides an analysis of the induction motor and the principles of vector control. Subsequently, the mechanisms of loss generation in induction motor drives are examined. The proposed simulation model is then introduced. Simulations performed in the MATLAB Simulink environment are used to verify the functionality of the model. Within these simulations, the influence of various controller parameters and the magnetizing current on the magnitude of individual losses is investigated for a defined speed and torque reference profile. Finally, the simulation results are discussed and evaluated.
