| Zusammenfassung: | A permanent magnet type electric rotating machine for which a Halbach array is utilized as a magnetic pole composition for the rotor (1), main magnets (3) that magnetize in the radial direction are composed of rare-earth magnets, auxiliary magnets (4) that magnetize in the circumferential direction are composed of ferrite magnets, and gaps are created between the main magnets and the auxiliary magnets in order to reduce the quantity of the rare-earth magnets without reducing the output torque of the electric rotating machine. |
