The invention discloses a rotor of an eddy current retarder. The rotor comprises a turntable, wherein an axial through hole is formed in the axial center part of the turntable; multiple radial through holes are formed in the turntable, and are communicated with the axial through hole; and the multiple radial through holes are uniformly distributed in the peripheral plane of the turntable. The center line of the radial through holes is deviated from the radius straight line of the rotor by a set angle. As the radial through holes are added in the turntable, when the turntable rotates, the heat generated on the turntable is directly dissipated through airflows; and the turntable has cooling holes, so that the cooling performance of the rotor is greatly improved, and the performance of the retarder is enhanced.
