The invention provides a disc type permanent magnet synchronous motor, an energy storage flywheel based on magnetic suspension support and a method. The disc type permanent magnet synchronous motor comprises an upper stator disc and a lower rotor disc. The stator disc comprises a stator iron core, the stator iron core comprises stator teeth and a stator yoke, an armature winding is a short-moment distribution winding and is wound on the stator teeth, and winding coils are arranged in a double-layer mode in the axial direction. The rotor disc is composed of a rotor yoke disc and permanent magnets of which the N poles and S poles are arranged in a staggered manner in the circumferential direction, wherein the number of magnetic poles of the permanent magnets is uniform and the permanent magnets are embedded on the upper surface of the rotor yoke. The structure of the motor for the energy storage flywheel is optimized, the motor is an axial magnetic flux motor, the flywheel rotor serves as a magnetic conductive yoke disc of the lower rotor disc, the motor and the generator are integrated, mutual inverse operation of electric/power generation is achieved, the motor can work in an electric state and a power generation state, and the structure of a flywheel energy storage system is simplified.
