As shown in Publication No. 27, two rows of belt-shaped steel plates are stamped in a staggered manner to form a substantially rectangular steel plate, and a plurality of these steel plates are laminated to form a stator core, and further, This iron core is constructed by providing bolt insertion holes penetrating in the stacking direction at four corners, that is, corners unrelated to magnetic properties. The stator core is then fixed to the frame by bolts inserted into the bolt insertion holes, but at this time, there are various shapes of frames in compressors for refrigerators, etc. (Tokuko Showa 62-4)
Publication No. 5779) and two (Special Publication No. 62-3031)
Publication No. 1). However, even in these irregularly shaped frames, by making the pitch between the screw holes the same size, the same iron core is usually used and parts can be made common.

良やこれに伴う始動不良を来招するという問題がある。(c) Problems to be Solved by the Invention However, according to the above structure, the same iron core is used even in irregularly shaped frames, which causes the following problems. In other words, a model with two mounting legs has to have a larger area in contact with the iron core than a model with four mounting legs, in order to obtain the desired tightening force, and it is difficult to obtain the desired tightening force when transporting the frame. There is a problem in that the iron core tends to become misaligned, resulting in defective air gap dimensions of the motor and associated starting failure.
一方、本件出願人は、取付脚が２本でも４本でも対処で

8, 39, 40 and slots 41, 42 are formed symmetrically with respect to the copper strip feeding direction and the copper strip width direction, and a large area is secured at one of both corners. There is a problem that the concave portions 35 and convex portions 36 of the contacting steel plates 30 cannot be made very large, and the mutual bite dimension A becomes small, the inside of the copper strip becomes large, and as a result, the material is increased, and it is not possible to do everything in terms of cost. Ta. Note that region III in the figure shows the contact surface when a frame with two mounting legs is attached.

ある。(Main) Effect The stator core of the present invention has the above-described configuration, by shifting one of the corners of the steel plate on the opposite row side in the steel strip width direction obliquely upward, while securing the area of the corner, Since it is possible to scrape off the lower edge, the recesses and protrusions on the opposite row side of the steel plate can be made larger and the opposite row side of the steel plate can be bitten deeper, thereby reducing the copper strip width dimension. , 2 mounting legs
Materials can be reduced while securing corner area when attaching a book frame. In addition, the bolt insertion holes formed at the four corners of the steel plate are formed at slightly rotated positions around the center of the circular hole, so the magnetic properties are not particularly impaired, and the pitch between the bolt insertion holes is the same as before. Since they are the same, the existing frame can be used as is. As a result, when installing a frame with two mounting legs, the mounting legs can be bolted to both corners formed in a large area to increase the tightening force, and the frame and the iron core may be misaligned. This makes it possible to prevent air gap size defects in the motor and related starting problems. As a result, it is possible to obtain a stator core in which performance can be maintained even when two or four mounting legs are used as a frame body, and furthermore, the material of the negative layer can be reduced.
