简介 In a permanent magnet type electric rotating machine, a rotor is arranged in a Halbach array, a main magnet magnetized in the radial direction is formed of a rare-earth magnet and an auxiliary magnet magnetized in the circumferential direction is formed of a ferrite magnet, and a gap is provided between the main magnet and the auxiliary magnet; as a result, the quantity of utilized rare-earth magnets is reduced without the output torque of the electric rotating machine being decreased.
