The invention discloses a double-cage rotor punching sheet, a double-cage rotor and a motor. The double-cage rotor punching sheet has a ring-shaped structure. The double-cage rotor punching sheet with the ring-shaped structure is provided with multiple rotor grooves along the circumferential direction, and the multiple rotor grooves are a combination of any two or three selected from double-cage convex grooves, double-cage ladder-shaped grooves and double-cage knife-shaped grooves. Starting current and groove leakage reactance of the motor can be reduced, skin effects and the rotation speed of the motor are enhanced, and the starting ability and the operation stability of the motor are enhanced.
