Abstract

PURPOSE:To readily obtain the similar effect to that of the case that a skew is formed even if no skew is formed at an armature core by obliquely forming the side face of the field pole head of a pole piece with respect to the axis of a rotary electric machine. CONSTITUTION:The side face of a body of a salient-field pole 3 is formed in parallel with the axis of a rotary electric machine at a field core 1 having the pole 3. The side face of the field pole head of the pole piece 4 is formed obliquely with respect to the axis of the machine in such a manner that a slot inlet 6 formed between the adjacent pole pieces is formed obliquely with respect to the axis. In this manner, the similar effect to that of the case that a skew is formed can be obtained even if the slots of the armature core are parallel with the axis.
