STATOR STRUCTURE FOR DOUBLY SALIENT PERMANENT MAGNET ELECTRIC MACHINE

摘要

The present invention relates to an electric apparatus having a stator core of a skew structure, capable of including a doubly salient permanent magnet facing a rotator or a mover, which performs relative motion. The stator core facing the rotator or the mover which performs relative motion comprises two or more cores having a salient pole shape at a period twice the pole pitch. The electric apparatus is to obtain skew effectiveness as salient pole center lines of the cores are arranged in parallel with a predetermined offset.
