The present disclosure discloses a rotor of an induction motor comprising a rotor body (1), alternating rotor teeth (2) and rotor slots (3) arranged along a circumference of the rotor body (1), and a plurality of grooves (4) provided at an end of the rotor teeth (2) or a plurality of voids (5) provided within the end of the rotor teeth (2) that are provided symmetrically about a center line (10) of the rotor teeth (2). The rotor and the induction motor having the rotor of the present disclosure can, for example, reduce the radial force of the stator caused by the slotting effect by about 50%. Therefore, the user's comfort can be greatly improved, while the efficiency of the induction motor can be improved, and the life of the induction motor can be prolonged.
