The two ends of the iron cores are provided with external separating plates. The centers of the iron cores and the external separating plates are provided with central holes which are used for being penetrated through by a main shaft. Each group of iron core comprises plural iron core sheets, and the iron core sheets are accumulated so that the iron core is formed. The circumferential surface of the iron core sheet is evenly provided with plural protrusions, and magnetic steel grooves are arranged among the protrusions. Each magnetic steel groove is internally provided with magnetic steel. A circle of annular long holes are evenly distributed on the iron core sheet. The two ends of the annular long holes have two semi-circle shapes. Poles of adjacent two groups of iron cores are arranged in a skewing way so that a complete circular hole is formed between the left semi-circle of the annular long holes on one group of the iron core sheets and the right semi-circle of the corresponding annular long holes of the other group of the iron core sheets. A bolt of the accumulated sheets penetrates through the circular hole so that the accumulated sheets are fixed. Two types of the iron core sheets can be punched by one set of mould. Besides, sheet accumulation and welding of two segments of the iron cores can be completed simultaneously.
