The invention provides a screw-free air magnetic isolation rotor, and relates to the technical field of permanent magnet synchronous motors. The problems that a conventional rotor is unstable in structure due to a connecting and fixing structure, the rotor magnetic isolation effect is poor, rotor magnetic leakage occurs, and a magnetic isolation bridge has defects are solved. The screw-free air magnetic isolation rotor comprises a rotating shaft, a rotor support, magnetic poles and permanent magnets. The rotor support is fixedly installed on the rotating shaft through a key, the magnetic polesare arranged in the rotor support and assembled into a rotor core, the magnetic poles and the rotor support are inserted and fixed through positioning rods, one end of each positioning rod located outside the rotor support is axially positioned through a check ring, and the other end of each positioning rod is clamped at the rotor support. An air gap used for magnetic isolation is arranged between the magnetic poles and
