<P>PROBLEM TO BE SOLVED: To provide a rotor which copes with high-speed rotation and has less loss, and to provide a rotary electric machine, an electric blower and an electric cleaner using the same. <P>SOLUTION: The rotor includes a columnar shaft 1, a cylindrical or arc-shaped magnet 3 which wraps the shaft 1 and is arranged at the external periphery of the shaft 1, a columnar rigid body (ring 4) which is arranged at the external peripheral surface of the shaft 1 so as to sandwich axial both ends of the magnet 3, and an insulative reinforcing material 5 which is arranged so as to cover part of the magnet 3 and the rigid body 4. This arrangement achieves the rotor, which has less eddy current loss, suppresses loss along with improvement in axial rigidity and intensity against a centrifugal force, and allows balance adjustment. <P>COPYRIGHT: (C)2010,JPO&INPIT |
