Abstract

PURPOSE:To obtain the same effect as a skew without forming the skew at an armature core of a rotary electric machine by laminating a plurality of core members so formed as to be sequentially displaced in a circumferential direction at the head of a field pole upon lamination of the pole to form a field core. CONSTITUTION:A plurality of field core members 1a which are formed integrally with field poles 3 and pole pieces 4 are formed on the inner peripheral side. The core members 1a are so formed as to maintain a distance S between the adjacent pole pieces 4 constant and to be displaced at the positions of the pieces 4 sequentially in a circumferential direction when the bodies of the poles 3 are superposed at the same position. The members 1 are laminated to form a field core 1. In this manner, even if no skew is formed at an armature core, the same effect as a skew from the armature core side can be obtained, and the equivalent effect to the skew can be obtained while facilitating the machining of the field core.
