1. an axial gap type coreless rotating machine, comprising:

  • Shell;

    Rotating shaft, this rotating shaft is rotatably supported in described shell;

    Two rotors, described rotor can rotate integrally with described rotating shaft and mutually in the face of arranging, there is the spacing of the axial direction along described rotating shaft between described rotor, described rotor comprises permanent magnet and two swivel plates, described permanent magnet is arranged at least one in the opposite face of described swivel plate ringwise around described rotating shaft, and the magnetic pole surfaces of described permanent magnet is located perpendicular to described rotating shaft;

    AndStator, this stator is fixed to described shell, and this stator is arranged in the air gap formed between opposed facing described swivel plate, and described stator comprises fixed head and coil, and described coil is arranged on the ring towards described permanent magnet on described fixed head ringwise;

    Wherein each described coil comprises the coiling formed by least one in the long limit of the cross section of the described winding wire of alignment and minor face by a branch of at least two winding wires with rectangular cross section, described coiling has the periphery being covered with insulating coating, and is wound in the described magnetic pole surfaces location making the long limit of the cross section of described winding wire perpendicular to described permanent magnet.
