PURPOSE:To reduce the size and to enhance the strength of a rotor for a synchronous motor without decreasing the magnetic efficiency by integrating permanent magnets, sheet-shaped magnetic units and terminal plates. CONSTITUTION:A plurality of permanent magnets 11 are arranged circumferentially, and terminal plates 12 are respectively aligned on both ends of the magnets 11. Many sheet-shaped magnetic units 13 adapted between the circumferential ends of the adjacent magnets 11 and engaged with the radial outside corner of the magnets 11 are laminated and disposed between the plates 12. The units 13 are integrated with the magnets 11 and the plates 12 by clamping members 14, 15 passing in laminating direction. |
