Influence of higher harmonics on losses in induction machines

The paper summarizes the power loss results in induction machines supplied with distorted voltage. The voltage waveform contained the fifth and seventh harmonics components of adjustable level in the range of 0% to 30%. The influence of the harmonic content on the core and windings losses is of particular interest. The paper investigates the additive impacts of basic and additional losses resulting from distorted power supply conditions.
