The paper deals with finite element analysis of magnetic field in the cross‐section of induction motor operating at different load conditions. Magnetic field is calculated for the case of symmetrical rotor cage and for several cases of rotor electrical asymmetry due to broken rotor bars. It is shown the relation between the increasing number of broken bars and unproportional distribution of induced rotor currents, which results as a degradation of steady‐state and dynamic performance of induction motor.

Discusses the 27 papers in ISEF 1999 Proceedings on the subject of electromagnetisms. States the groups of papers cover such subjects within the discipline as: induction machines; reluctance motors; PM motors; transformers and reactors; and special problems and applications. Debates all of these in great detail and itemizes each with greater in‐depth discussion of the various technical applications and areas. Concludes that the recommendations made should be adhered to.
