Permanent Magnet Embedded Electric Motor, Compressor, And Refrigerating And Air.Conditioning Device
Abstract: A permanent magnet embedded electric motor comprises: a stator core (8) disposed inside a frame (6) and having a back yoke (8c) and a plurality of pole teeth (8d); a rotator (22) disposed on the inner diameter side of the pole teeth (8d); and a plurality of compression portions in which compression stress occurs that is higher than compression stress that occurs in the back yoke (8c) attributable to pressing force occurring between the frame (6) and the back yoke (8c). In the permanent magnet embedded electric motor a compression portion group (180) in which two or more of the compression portions (18 1 18 2) are included as one set is disposed on a stator core outer circumferential portion (8a) that is the outer circumferential portion of the back yoke (8c) corresponding to each of the pole teeth (8d). The total sum of the rotation direction widths (A1 A2) of the compression portions (18 1 18 2) constituting the compression portion group (180) is smaller than the radial direction thickness (B) of the frame (6).
