Loss evaluation of an induction motor model core by vector magnetic characteristic analysis

This paper presents results of iron loss evaluation of an induction motor model core by using the finite element method considering two-dimensional vector magnetic properties. In order to reduce rotational iron losses, which generate in the stator core, we tried to make holes at the tooth base parts. As a result, the rotational flux distribution was effectively controlled by making holes. In this paper, obtained knowledge about iron loss control with holes in the stator core is presented and discussed.
