The utility model discloses a rotor structure of a permanent magnet synchronous servo motor, which comprises an iron core body and a rotor shaft. The iron core body is provided with a copper guide bar, which is tightly hoisted on the iron core body through stainless steel bands. The two ends of the iron core body are provided with a rotor end ring, and the rotor end ring is provided with an annular groove, an end ring groove and a circular through hole. The end ring groove and the copper guide bar are suitable for each other. The end of the core body is provided with a shaft hole, a permanent magnet slot, a heat sink and a magnetic isolation bridge. The shaft hole is inserted with a rotor shaft. The rotor shaft and a circular through-hole interference fit are arranged in the permanent magnet slot. Four permanent magnets are arranged in the permanent magnet slot. The magnetic isolation bridge is located at both ends of the permanent magnet slot. The inner wall of the heat sink is provided with a heat sink, the shaft hole, the permanent magnet slot, the heat sink and the separator. The magnetic bridges are located inside the annular grooves. The utility model comprises three copper end rings and three steel end rings through the rotor end rings, and the copper end rings and the steel end rings are interactively stacked to reduce the stress concentration of the iron core body at high speed.
