がよくなる。As explained above, the present invention includes a first iron core plate having a magnetic pole piece on one side and a convex portion on the other side, and a connecting plate in which the first iron core plate is arranged in a circle with the convex portion inside and only the number of poles is arranged. A stator is formed by laminating and caulking a plurality of connected second core plates, and the stator has a shape in which a convex portion is removed from the second core plate on the upper and lower end surfaces of the stator. After positioning and caulking the material at the convex part, the convex part and the connecting plate of the second iron core plate were separated from the stator, so that the convex part could be used for positioning and fixing the non-magnetic material to the stator. It is used for various purposes, making assembly easier and improving productivity.Since the magnetic pole parts are connected using non-magnetic material, magnetic flux does not concentrate at the connecting part, preventing magnetic flux leakage and making all the magnetic flux effective. This improves motor efficiency and improves motor performance.

。In addition, since the non-magnetic material is formed on the convex part and the connecting plate so that it does not overlap, since the convex part and the connecting plate are made of the same material, it is possible to separate them at the same time, improving workability. By separating the parts, the inner diameter accuracy of the rotor insertion hole can be easily ensured, and the air gap with the rotor is stabilized.
