Rotary electric machine
First Claim
1. A multi-phase rotary electric machine of an alternating current electromagnet in which a stator or rotor is formed by combining a bobbin winding and a magnetic pole iron core, whereina magnetic pole shape facing an air gap portion formed between said stator and said rotor has a projection portion which is overlapped with another phase, and an electromagnetic agreement with each phase is disposed in a spaced arrangement of a magnetic pole in said air gap and said magnetic pole of each phase is strengthened with a contact and a laminated layer formed by divided cores, whereby a rotation magnetic field is formed smoothly and a performance and a vibration are improved.

Abstract
A magnetic pole for facing an air gap with a stator is formed with a parallel quadrilateral shape or a quadrilateral shape having a skew effect and is obtained by a single iron core or plural iron cores. To make simply a winding structure of a stator and a rotor of an alternating current rotary electric machine, by a bobbin structure a magnetic field formation of a magnetic pole portion is formed. A magnetic pole structure having a projection portion is provided to form an overlap structure with another phase magnetic pole. An electromagnetic combination of each phase is strengthened and each phase magnetic poles is carried out a systematic separation, dispersion, and an arrangement.
