1. An axial flux magnet motor stator assembly comprising:
a stator ring in the shape of a circle, the stator ring having at least two stator winding columns extending in the axial direction uniformly in the circumferential direction,
a stator bottom cover with a coil winding assembly connected to the stator ring with a plurality of terminals, the coil winding assembly includes a coil body and a coil hole provided on the coil body, and the coil winding assembly is connected to one of the stator winding columns through a coil holding slot; and
a stator holding slot formed between two adjacent stator winding columns, the stator holding slot being provided with openings on both sides in the radial direction;
wherein a bottom of the stator ring directly or indirectly contacts an inner bottom surface of the stator bottom cover, the stator bottom cover includes a bottom cover outer ring and a bottom cover inner ring located on an inner side of the bottom cover outer ring, a bottom cover installation groove is formed between the bottom cover outer ring and the bottom cover inner ring for installing the stator ring, and a plurality of bottom cover filling slots are formed between the stator ring and the bottom cover inner ring, and
wherein each of the the terminals are located in at least one of the bottom cover filling slots and fixed by an adhesive.
