Energy consumption and losses calculation approach for different classes of induction motor drives

The paper deals with development of program block for estimation of energy consumption by induction motor drive. The block is created in MATLAB/Simulink application. The block topology, parameter-setting window and equations used in block are shown. The proposed method used in drive simulation allows estimating consumed energy, energy losses and energy efficiency of different drive systems. The calculation results with using developed block at different induction motor control methods are illustrated
