High efficiency and reduction of loss at high rotation speed can be attained with a simple configuration. The M/G includes a disc-shaped rotor 12 coupled to a main shaft 10 rotatably supported by a housing 20, 22. The rotor 12 has a permanent magnet array 14 providing a Halbach array magnetic field. Armature coils 16 are arranged in a disc-shape array to oppose to the permanent magnet array 14 and fixed to the housing 20, 22 as stators. A disc-shaped magnetic field member 24 is made of a magnetic material and arranged in a recessed part 22c formed in the housing 20, 22 at a side of the armature coils 16 opposite to the permanent magnet array 14.
