PROBLEM TO BE SOLVED: To provide a stator iron core which can improve the space factor of winding to a magnetic pole, can prevent the transformation of the magnetic pole accompanying winding work and besides can make the accuracy in form at the time of having formed a magnetic pole by coupling a magnetic pole stack with the main body of the magnetic pole superfine, aiming at a stator iron core which consists of a yoke/magnetic pole body stack having a yoke and a specified number of magnetic pole bodies and a specified number of magnetic pole stacks and is constituted by forming a specified number of magnetic poles inward of the yoke by coupling the magnetic pole stack with the above magnetic pole main body thereby fixing it integrally. SOLUTION: For the stator iron core, the tip of the magnetic pole body in the yoke/magnetic pole body stack is provided with a coupling part, while the magnetic pole stack is provided with a fitting hole which can be fitted on the coupling part from the direction of the axis of the yoke/magnetic pole body stack. Furthermore, the section of either the coupling part or the fitting hole is provided with a small bulge to engage with the other section, and the coupling part is fitted in the engaging hole thereby coupling the magnetic pole stack with the magnetic pole body and also fixing the magnetic pole body with the magnetic pole stack integrally by means of the small bulge.
