Summary:The utility model discloses a rotor punching sheet, a rotor structure and a permanent magnet synchronous motor, the rotor punching sheet comprises a rotor punching sheet body, the rotor punching sheet body is provided with a plurality of groove bodies used for placing magnetic steel, a first air groove is arranged between every two groove bodies, and a second air groove is arranged between every two groove bodies. A magnetic isolation bridge used for reducing the leakage flux of the magnetic steel is arranged between the groove body and the first air groove, and the magnetic isolation bridge is in a step shape. The rotor punching sheet body is integrally formed, and a plurality of connecting holes used for connecting fasteners are formed in the rotor punching sheet body. According to the rotor punching sheet, through the arrangement of the step-shaped magnetic isolation bridges, the magnetic resistance areas are formed between the groove bodies and the first air grooves so as to reduce the magnetic leakage fl
