摘要： PROBLEM TO BE SOLVED: To avoid beforehand concentration of stresses on a permanent magnet even if high-speed rotation is performed. SOLUTION: A rotor, over a nearly total area of its gap between at least circumferential surfaces 6a, 6b of the permanent magnet 6 and circumferential surfaces 11a, 11b of an opening 11, is coated (filled) with an adhesive agent 12 (a filling member). Consequently, a nearly total area of the circumferential surfaces 6a, 6b of the permanent magnet 6 is constituted so that the area is fixed to the circumferential surfaces 11a, 11b of the opening 11 through the adhesive agent 12. Such constitution is provided as an applied region and a non-applied region of the adhesive agent 12 are not intermingled in an axial direction of the permanent magnet 6. Deterioration of characteristics of the rotor 1 is thereby prevented, and reliability is improved. COPYRIGHT: (C)2007,JPO&INPIT
