摘要： A stator includes a stator core (13) having a substantially cylindrical back yoke (11) and a plurality of teeth (12) extending radially inward from the back yoke (11). The stator core (13) includes a plurality of stator core pieces (13a) each having one tooth (12) and a yoke piece (11a) forming part of the back yoke (11). On the inside of the back yoke (11) in the radial direction, adjacent ones of the stator core pieces (13a) directly contact each other, or contact each other with a member, as an intervening thing, interposed between the adjacent ones of the stator core pieces (13a).

摘要： A core (11, 21) includes a laminated body (12, 22) including a plurality of electrical steel sheets stacked one on another. The laminated body (12, 22) includes a contact area (C) between a pair of adj acent electrical steel sheets of the plurality of electrical steel sheets. The contact area (C) includes a first friction area (F1) and a second friction area (F2) with friction coefficients different from each other.

摘要： When the outer peripheral surface of a resin member (60) is a first joining surface (71) and a surface in contact with the first joining surface (71) on the inner peripheral surface of a barrel (22) is a second joining surface (81), the method for manufacturing a compressor includes: a first step of joining the first joining surface (71) to the second joining surface (81), and in the first step, upon joining, to the second joining surface (81), an intermediate portion (74) of the first joining surface (71) between a first end (72) and a second end (73) facing each other, spaces (S) between the first joining surface (71) and the second joining surface (81) are formed between the first end (72) and the intermediate portion (74) and between the second end (73) and the intermediate portion (74).

摘要： A stator (5) includes a stator core (510) in which an annular back yoke (511) is integrated with a plurality of teeth (512) circumferentially arranged on the back yoke (511) at intervals, and an insulator (530, 1530) that sandwiches the stator core (510) from both axial sides of the stator core (510). The insulator (530, 1530) is molded integrally with the stator core (510) through resin molding in such a way that the insulator (530) covers an inner surface of a slot portion (514) of the stator core (510). Thereby a stator that can be assembled by a simpler process is provided.

摘要： Techniques to reduce the d-axis inductance in a rotor are provided. According to one embodiment in the present disclosure, a rotor 20 includes permanent magnets 22 and 23 housed in magnet slots different from each other formed in an iron core 21, and arranged in series magnetically; and a flux barrier (cavity 24) provided to be close to an end in a direction orthogonal to a direction of a main magnetic flux, for each of the permanent magnets 22 and 23 arranged in series magnetically. Two instances of the flux barrier corresponding to the respective permanent magnets 22 and 23 arranged in series magnetically, communicate with each other. According to another embodiment in the present disclosure, a motor 1 includes the rotor 20 described above.

摘要： A plurality of iron cores (10, 20) and a plurality of supporting members (2a, 4) are provided. At least one of the iron cores (10, 20) is supported by any one of the supporting members (2a, 4) via a resin member (40). At least either of the iron core (10, 20) and the supporting member (2a, 4) that are mutually supported via the resin member (40) is provided with an elastic deformation portion (18) configured to press the resin member (40) against the other one of the iron core (10, 20) and the supporting member (2a, 4) by elastic force.
