Title: ROTATING ELECTRIC MACHINE
Abstract:
A rotating electric machine is provided with a stator core (11) in which a plurality of laminated sheets (15) are laminated in the shaft center (P) direction of a rotating shaft, said laminated sheets being alternately provided with arc surfaces (16) arced about the center of the rotating shaft and linear surfaces (17) at the outer edge thereof. The stator core (11) is provided with a shifted lamination portion (13) in which the laminated sheets (15) are laminated such that reference positions (SL) preset at the outer edges of the laminated sheets (15) change in the circumferential direction. When the number of the laminated sheets (15) constituting the shifted lamination portion (13) is denoted by X, the number of the arc surfaces (16) with which one laminated sheet (15) is provided is denoted by Y, and it is assumed that n rounds of rotations are made in one circumferential direction (C1) of the laminated sheets (15) constituting the shifted lamination portion (13), an angle θ[°] formed by the reference lines connecting the reference positions (SL) and the shaft center (P) satisfies θ = (360 × n)/X and θ < 360/Y in two of the laminated sheets (15), which are sequentially laminated in the shaft center (P) direction.
