It is well known that a rotational magnetic flux exists in the core of a three-phase transformer or a rotating machine. To date, the iron loss produced by the rotational flux has not been considered in calculating the core loss. A high accuracy method for calculating the rotational loss whose aim is to improve the efficiency of the induction motor is proposed. The flux distribution and the space vector of flux density of single-phase and three-phase induction motors were analyzed taking into account the core saturation and time harmonics of flux density. The effect of rotational flux harmonics on the core loss was also analyzed.
