The invention discloses a gas compressor, a motor and a foil radial aerodynamic bearing. The foil radial aerodynamic bearing comprises top foils, bump foils and a bearing bush, wherein a first limiting plate and a second limiting plate area arranged at a first end and a second end of each top foil in the circumferential direction of the bearing bush respectively, and a third limiting plate is arranged at a first end of each bump foil in the circumferential direction of the bearing bush; and limiting slot groups are arranged on the inner surface of the bearing bush, each limiting slot group comprises a first limiting slot and a second limiting slot, the first limiting slot and the second limiting slot of one limiting slot group are matched with the first limiting plate and the second limiting plate of the corresponding top foil respectively, two ends of the top foil cannot be contacted with a rotor, furthermore, the end parts of the top foil cannot scratch against the rotor, the top foil of the bearing is effe
