Containment band for permanent magnet generator
A rotor has a rotor body for rotation about a shaft. A plurality of permanent magnets are spaced circumferentially about the rotor body. A containment band is positioned radially outwardly of the permanent magnets. The containment band has a containment band coefficient of thermal expansion. The per...

| Zusammenfassung: | A rotor has a rotor body for rotation about a shaft. A plurality of permanent magnets are spaced circumferentially about the rotor body. A containment band is positioned radially outwardly of the permanent magnets. The containment band has a containment band coefficient of thermal expansion. The permanent magnets have a permanent magnet coefficient of thermal expansion, taken parallel to a magnetic alignment. A ratio of the containment band coefficient of thermal expansion to the permanent magnet coefficient of thermal expansion is less than or equal to 1.15. |
