WIPO Patent Application WO/2016/178368
Kind Code:
A1
Abstract:
In the present invention, a stator (40) is assembled by stacking a plurality of magnetic steel sheets each having a teeth part (43), and the steel sheets comprise: connected teeth steel sheets (30) in which the leading ends, on the inner-circumferential side, of the teeth parts (43) are circumferentially connected by connection parts (45) to form an annular shape; and non-connected teeth steel sheets (31) in which teeth parts (43) are not connected and are individually independent. The connected teeth steel sheets (30) and the non-connected teeth steel sheets (31) are connected in the axial direction by crimped portions (44) provided to the teeth parts (43), and the thickness of each connection part (45) is formed smaller than the thickness of the other portions of the steel sheet.
