PURPOSE:To endure a centrifugal force at ultrahigh speed rotating time by winding glass fiber impregnated with thermosetting resin on the outer periphery of a permanent magnet plural times and thermally setting the resin. CONSTITUTION:A plurality of permanent magnets 3 are disposed on the other periphery of a cylindrical yoke 1 secured to the shaft 2 of a permanent magnet rotor, and the magnets 3, the yoke 1 and the magnets are secured therebetween by an adhesive 4. Glass fiber 5 impregnated with thermosetting resin is wound plural times on the outer periphery of the magnet without gap to form the first layer 5a. The winding start 5s and end are thermally set in the state that the fiber 5 is lap wound and interposed therebetween. |
