Determination of Iron-Core Losses Under Influence on Third Harmonic Flux Component
The core loss for a magnetic material under excitation can be estimated from the flux density versus the field-strength loops or B -H loops. A method is presented for predicting the position, size, and number of minor loops ...
Losses Influenced by Third-Harmonic Flux in Induction Motors
The trend toward increasing flux density in modern induction motors results in the increase of third-harmonic flux in the magnetic paths. The effects of third-harmonic flux on energy losses in induction motors are discussed. ...
