An aerodynamic thrust bearing, a motor and an air compressor. The bearing comprises a top foil plate, a corrugated foil plate and a bottom plate which are arranged in sequence; connecting segments formed by extending downwards are respectively arranged at the positions of a top foil connecting outer ring corresponding to a plurality of top foil fixing ends, and radial outer side plate edges of the top foil fixing ends are connected to the corresponding connecting segments; accommodating cavity through grooves arranged in the length direction of the top foil fixing ends are respectively formed in the positions of a bottom plate main body corresponding to the plurality of top foil fixing ends; coupling portions are formed by circumferentially extending upwards and towards the corresponding top foil fixing ends from the groove walls of the sides of the accommodating cavity through grooves opposite to the top foil fixing ends; and the top foil fixing ends are inserted in the accommodating cavity through grooves b
