Disc type rotor sinusoidal AC motor

The utility model discloses a disc type rotor sinusoidal AC motor which can be used a generator or an electric motor, the disc type rotor sinusoidal AC motor is a generator when the rotor is mechanically driven, and the disc type rotor sinusoidal AC motor is an AC electric motor when the coil is electrified by an alternating current. The disc type rotor sinusoidal AC motor is provided with a magnetic loop being simple in path and less in magnetic loss, thus, the disc type rotor sinusoidal AC motor is less in pulsation to improve the mutual conversion efficiency of the mechanical energy and the electric energy, and the disc type rotor sinusoidal AC motor reduces the material consumption of magnetic poles to reduce the manufacturing cost and to be easy to radiate heat. The disc type rotor sinusoidal AC motor includes a casing, a rotating shaft, the rotor and a stator, the rotor includes at least two disc-shaped bodies which are divided into a first disc-shaped body and a second disc-shaped body, the disc-shaped
