Document Type and Number:
WIPO Patent Application WO/2018/131205
Kind Code:

Abstract:
A stator core (2) formed by laminating a plurality of sheet materials (10) in the shaft direction (Y) forms a circular shape in such a way that a plurality of magnetic pole pieces (5) and at least one yoke piece (6) are connected such that the ends of the magnetic pole pieces (5) and the yoke piece (6) in the circumferential direction (Z) can be bent each other. Each of the magnetic pole pieces (5) has a first back yoke portion (51) and a tooth portion (52) projecting toward the inside (X1) in the radial direction. The yoke piece (6) has a second back yoke portion (61). The first back yoke portion (51) and the second back yoke portion (61) form a back yoke portion (7) that is the outer circumferential portion of the stator core (2). A coil (4) is formed by winding a winding wire (41) around the tooth portion (52) with an insulator (3) interposed therebetween.
