Summary:The invention discloses a rotor structure for reducing cogging torque, which comprises a shaft, a rotor hub, an N-pole magnetic pole unit, an S-pole magnetic pole unit and a baffle plate, the N-pole magnetic pole unit comprises an N-pole magnetic pole unit n1 and an N-pole magnetic pole unit n2 which are different in boundary dimension, the S-pole magnetic pole unit comprises an S-pole magnetic pole unit s1 and an S-pole magnetic pole unit s2 which are different in boundary dimension, and the baffle plate is arranged between the shaft and the baffle plate. Wherein the N-pole magnetic pole unit n1 and the S-pole magnetic pole unit s1 are the same in boundary dimension and opposite in magnetizing direction, and the N-pole magnetic pole unit n2 and the S-pole magnetic pole unit s2 are the same in boundary dimension and opposite in magnetizing direction; the invention further discloses a permanent magnet motor adopting the rotor structure. The problems that a traditional skewed slot or skewed pole process is comp
